Where Science and Common Sense Come Together for Better Engine and Tractor Performance

Offering small engine repairs, including Kohler, Briggs & Stratton, Tecumseh, etc. We are a local and mail-order garden pulling tractor parts and repair service business, and offering small engine repairs, various garden tractor pulling parts and repair services, various Cub Cadet garden tractors parts, sharpening service, steel welding, brazing and general machine shop services. Will do our best to fix anything and everything. I have a well-equipped machine shop, so there's not much I can't do. We are very particular about our repairs and the quality of the products that I offer for sale. I fabricate and use the same quality parts that I sell to our customers in our personal lawn and garden equipment and pulling tractors. Nothing less. Because if I don't feel comfortable or satisfied about a certain part that I make or sell, then I know you won't either. I also offer honest and reliable repairs. I won't sell you parts or services you don't need. And we've always been a "green" company! I reduce, reuse, recycle and restore when others just "throw it away." In other words, we'd rather repair an old part than replace it with a new one.

If you have a request, needs or questions concerning machine work within our facility's capabilities, please give me a call at the number below Ê during regular business hours. Our fully insulated and heated 1,368 square foot shop is well-equipped to repair most makes and models of small engine equipment, pulling tractors and just about anything else. I have a small machine shop equipped with.

Old Plank Rd. | Columbia, MO (Missouri) 65203-9136 USA | Phone: 1-573-256-0313 (shop) | 1-573-881-7229 (cell; when leaving a voice message, please speak slowly when giving your phone number). Please call Monday-Friday, except holidays, 9am to 5pm, Central time zone. If no answer, please try again later. (When speaking with Brian, please be patient because I stutter.) A-1 Miller's shop is open to the public from 9am to 5pm, including weekends, except holidays. Please call before coming so I'll be here waiting for your arrival. E-mail: pullingtractor@aol.com. Directions to our shop | 1501 West Old Plank Road, Columbia, MO - Google Maps or Map of 1501 West Old Plank Road, Columbia, MO by MapQuest. You can also make the drive to A-1 Miller's shop to personally drop off and pick up your engine, transaxle, tractor, etc. for rebuilding or repairs. "The road to a friend's house (or shop) is never long."

To place an order, please call the number below Ê or send an email with your name, complete and correct postal address and phone number and so I can figure the total with shipping cost and USPS Tracking. For payment options for parts ordered or services performed, or to make a donation to my websites, I accept cash (in person), USPS Postal Money Orders, cashier's checks, business checks, MasterCard, VISA, Discover, American Express (please add 2.5% to the total for the credit/debit card processor's surcharge), Western Union Money Transfer, MoneyGram Money Transfers or Popmoney. (If a part for a specific purpose is special ordered, your debit/credit card may be charged for the full amount or as a deposit right after your order is placed; please do not send your debit/credit card information in email!) Or you can pay me through PayPal. (My PayPal account name is my email address. And be sure to mention in PayPal a description of what the payment is for.) If sending a money order, please include a note in the envelope with your name, complete and correct postal address, phone number and a description of what the payment is for. My mailing address and phone number are below Ê . I'll make a note of your order, and I may have to order some of the parts, which should take a few days to come in, but I will send the parts to you as soon as I have everything in stock after I receive your payment.

IMPORTANT - When sending your part(s) to me for rebuilding or repair, package everything securely so the item(s) won't get damaged in shipping and please include a note in the box with your name, mailing address, phone number (in case I have any questions) and a description of what you want done. When shipping heavy parts, it's best to put a slightly smaller box inside a larger box, to double the strength and integrity of the package. Because the clumsy "gorillas" or incompetent and uncaring workers that work for certain delivery services mishandle the heavy packages and don't care. And when the work is completed, I'll either call or email you an invoice with the total including shipping & handling.

To figure the shipping cost, I weigh the package with the parts, then I go online to the USPS Postage Rate Calculator website. I type in the weight, my zip code and your zip code, then it shows me the prices for various ways to ship the package. I always choose US Postal Service because I believe that's the most fastest, economical and reliable method.

Shipping: (United States and it's territories)
To save you shipping charges, item(s) in a package or cushioned envelope weighing less than 13 oz. is sent by First Class Mail for a 2-6 day delivery. Most packaged item(s) weighing over 13 oz. is sent by US Priority Mail for a 2-3 day delivery. To save you even more on shipping heavy items, I always try to use the US Postal Services' Flat Rate Priority Mail envelope and boxes (if the item(s) can fit inside the envelope or boxes). Some heavy items weighing no more than 70 lbs. is sent by US Mail Parcel Post. Item(s) weighing over 70 lbs. is sent by FedEx Ground. Again, if you're the kind of person who don't trust delivery/shipping companies (mis)handling your high-dollar and fragile merchandise, you can make the long drive to A-1 Miller's shop to personally drop off and/or pick up your engine, transaxle, tractor, etc.

We Ship to Canada and Worldwide -
Item(s) in a package or cushioned envelope weighing less than 1 lb. is sent by US Postal Service Airmail Letter Post for a 4-7 days delivery. Packaged item(s) weighing over 1 lb. and up to 66 lb. is sent by US Postal Service Airmail Parcel Post for a 4-10 days delivery. I cannot use the US Postal Services' Flat Rate Priority Mail envelopes and boxes to ship outside U.S. territories. Item(s) weighing over 67 lbs. or more is sent by FedEx Ground or equivalent services.

We Accept PayPal, Visa, MasterCard, American Express & Discover Credit & Debit Cards
^{(When placing an order through PayPal, please provide a list of which
parts you need.)}

To make a payment to me through PayPal, go to PayPal's secure website ( https://www.paypal.com/ ) and click on Send and Request -> Pay for goods or services. Type in my email address, or copy and paste this: pullingtractor@aol.com, the amount and follow the directions. Be sure to mention in PayPal a description of what the payment is for. After you've finished, PayPal will send me an email notifying me that you have made a payment to me for the product(s) or services and amount entered. Then I go to their website and direct PayPal to deposit the money in my bank account. And I will send the parts to you as soon as I receive your payment. But I may have to order some of the parts if they're not in stock, which should take a few days. In that case, I will send you the parts as soon as they come in.

Carburetor Parts, Fuel System Parts, Fuel Pumps, Carburetors and Machine Shop Services

NOTE: All parts listed here are NEW, unless otherwise stated. I do not sell cheap junk! As a matter of fact, many of the OEM Kohler K-series and Magnum engine parts are still made in the U.S. The Kohler Courage engines and parts are made in China. As a matter fact, Kohler owns two factories in China that make the parts. And most aftermarket parts listed in this website are also made by Kohler to Kohler's strict specifications. Kohler just place the part(s) in a generic-looking box or package and sell them for less money. So when purchasing a genuine OEM Kohler part that come in a box with the Kohler name on it, you're really just paying more money for the name on the box. The aftermarket parts that's not made by Kohler are of very high quality. I do not sell junk. And as far as some parts being discontinued - either the parts didn't sell well or the EPA is trying to phase out parts for the old cast iron block flathead engines because they produce more air pollution than the newer OHV engines.

Included in overhaul/rebuild kit above È.

Bottom Main Fuel Adjuster -

The bottom high speed main fuel adjuster is not an OEM Kohler part and not a modification by Kohler. This part is an absolute must for a competition pulling engine that runs at very high RPM or wide open throttle. It provides no high-performance engine enhancements whatsoever. It's an add-on feature that replaces the OEM float bowl retaining bolt above È only to prevent wearing or enlarging the fuel suction hole in the main jet by the OEM high speed needle adjuster due to normal engine vibration at very high RPM or wide open throttle engine operations. (Whoever says that the use of this part will increase the performance of an engine obviously do not know what they are talking about, or they are in the business of selling new main jet/nozzle (emulsion tube)s, which can be very difficult to remove.) The carburetor must be converted to the bottom adjuster when using this part. Fits all Carter or Kohler #26, #28 and #30 carburetors used on Kohler K-series and early Magnum engine models K241/M10, K301/M12, K321/M14, K341/M16 and K361. Can also be used in the carburetor on all Briggs & Stratton opposed twin cylinder flathead engines to "fine tune" the air/fuel mixture. Read below how to covert the carburetor for use with a bottom main fuel adjuster. $17.00 each, plus shipping & handling.

Alcohol resistant neoprene rubber O-ring seal for bottom main fuel adjuster above È. Replace dry-rotted O-ring which can cause dangerous leaking fuel. Dimensions: 5/32" i.d. x 9/32" o.d. .25¢ each, plus shipping & handling.

How to Easily Convert the Carter or Kohler #26, #28 or #30 Carburetors to the Bottom Main Fuel Adjuster - An ingenious and innovative concept by Brian Miller, because nobody else advertise this type of foolproof conversion. Top of page

This conversion has been proven many times to function flawlessly for a high RPM or wide open throttle competition pulling engine. The bottom main fuel adjuster is not an OEM Kohler part and not a modification by Kohler. Actually, this is the same principle that was used on Briggs & Stratton's 6-12.5hp vertical shaft flathead engine carburetors, and it works excellent! It provides no high-performance enhancements and no "added horsepower" to the engine whatsoever. This part is an absolute must for a competition pulling engine that runs at very high RPM or wide open throttle. It's an add-on feature that replaces the OEM float bowl retaining bolt only to prevent wearing or enlarging of the fuel suction hole (orifice) in the main jet by the pointed end of the OEM high speed needle adjuster due to normal vibration at very high RPM or wide open throttle engine operation. Whoever says the use of the bottom main fuel adjuster will increase the performance of an engine obviously do not know what they are talking about, or they are in the business of selling new main jet/nozzles, which can be very difficult to remove. Rather the main jet/nozzle can be easily removed with a screwdriver or drilled into and chiseled out. If the main jet/nozzle is not removed carefully, damage to the carburetor could result, rendering it useless. Also, with a bored-out venturi, a 60º angle will need to be precisely ground on the end of the nozzle in exact alignment with the centerline of the throttle bore so engine vacuum will draw fuel through the main jet/nozzle immediately upon acceleration. A bored-out venturi and reworked carburetor is when the carburetor is modified for maximum performance for general yard and garden use, and/or for competition pulling.

Due to normal engine vibration at high RPM or wide open throttle operation, the pointed tip on the OEM top high speed air/fuel needle adjuster will "severely vibrate around" inside the main jet hole (orifice) of the main jet/nozzle. The tip of the flexible brass needle adjuster will eventually wear the main jet hole (orifice) so large, the engine will run rich on fuel, and over time as the hole (orifice) wears even larger, further lean adjustments will be impossible. This will happen with gas or alcohol fuels. There is no way to prevent this from happening except convert the carburetor to the bottom main fuel adjuster. And when the carburetor is reworked with the venturi bored-out (straight-through throttle bore design) for high performance use, this equals the performance of the popular "Super Carb" competition pulling carburetor. (Which I think is a very fine performance carburetor.) Also, if you're wondering if the presence of the OEM high speed adjuster tube will slow the incoming airflow through the "straight through" throttle bore, well, the throttle plate and shaft are about 30% wider than the high speed adjuster tube, even with the throttle shaft ground/milled narrow or thin to allow for more airflow through the carburetor.

How to Convert a Carburetor to the Bottom Main Fuel Adjuster:

Break off the tip on the top OEM high speed needle adjuster at the lower idle fuel feed hole (orifice) with pliers. Make sure inside the tube is open and not clogged with dried gas or debris to allow fuel to still be drawn through the tube so the engine will idle). And bevel the end of the tube so fuel can flow past it smoothly at high RPM. Preferably use an OEM adjuster with a damaged tip for this conversion. There's no need to ruin a good adjuster for this.
Remove the OEM compression pressure spring from the high speed adjuster and install a spacer or stack of flat washers measuring approximately 9/32" in height in place of the spring. The 9/32" height positions the end of the high speed adjuster tube about midway in the float bowl and about 3/16" above the main jet hole (orifice) so fuel will be drawn through the tube so the engine will idle.
Reinstall the top OEM high speed needle adjuster in the carburetor body with the spacer or washers and tighten it in place, making it fixed in place and non-adjustable.
Reinstall the float, bowl, etc., and install the bottom main fuel adjuster (instead of the OEM float bowl retaining bolt), and tighten the adjuster. IMPORTANT - Before tightening the bottom adjuster, back off the needle (in the adjuster) to keep it from jamming into the main jet hole, possibly causing damage or stripping the threads in the carburetor body!
Install the carburetor on the engine, linkages and fuel hose on the carburetor, start the engine, and adjust the idle air/fuel mixture screw and the high speed air/fuel mixture bottom adjuster until the engine runs smooth at idle and at high RPM or wide open throttle. NOTE: Absolutely nothing needs to be done to the idle fuel passageways or the idle fuel mixture adjusting screw. Just leave them alone. The engine should idle fine after the conversion. And there's no need to install a small brass tube next to the float for the idle fuel passageway. The tube could interfere with the operation of the float. Return To Previous Paragraph or Section

Kohler Anti-Backfire/Engine Shut-Off Solenoid Valve Kit. This particular part came on various models K181, M18 and K582 engines, and virtually all M20 and MV20 engines. The solenoid valve [in the carburetor] shuts off the engine when the ignition is turned off. The way it works is, upon engine shut down, the valve blocks air from entering the float bowl through the atmospheric vent opening (air passageway from inside the float bowl area to outside of carburetor; which is where the solenoid valve is located). When this happens, the engine can't draw fuel, so it shuts down. The solenoid is energized the entire time the ignition switch is on. The reason Kohler installed this feature is to prevent the engine from producing a loud backfire out the muffler when it's shut off. With the solenoid in working condition and upon engine shut down, no unburned fuel enters the hot muffler, therefore, no backfire. When the solenoid fails or goes bad, the engine will not start.

OEM Kohler part # 25 755 05-S. $82.00 each, plus shipping & handling. Not available in aftermarket. L

NOTE: Being the solenoid for various M18, M20 and MV20 engines (OEM Kohler part # 25 755 06-S) is no longer available, to convert these engines without use of the solenoid, remove the failed solenoid and valve, cut some short threads in the hole (remove the float bowl first and use compressed air to clear out the metal cuttings), and install a 3/8" Allen set screw in the hole. Don't thread the set screw deep in the hole, or it will block off air from entering the float bowl. Without a solenoid, the engine would require a different ignition switch to shut off the spark. And the engine should be idled down before shutting it off to lessen the chance of a backfire out the muffler.

High Speed Air/Fuel Mixture Needle Adjuster Screws for Carter #16, #18, #20, #22 Carburetors. NOTE: Various high speed adjusters are designed for a particular carburetor. I list the part number of the carburetor to match the type of adjuster it requires. Kohler don't give their dealers much information on this. I did some research, and I have several used carburetors in stock, and compared the type of adjuster to the part numbers on each carburetor and found that some are in fact different. The holes midway on the high speed adjuster allows a small amount of air to be mixed with fuel through the idle circuit so the engine won't idle too rich or too lean on fuel. And with no holes present midway allows full flow of fuel through the idle circuit, which when used in a wrong carburetor, may cause the engine to idle too rich on fuel. So if an engine idles well (with the present adjuster), then the carburetor has the correct adjuster. Also, being the high speed adjusters are made of soft brass, if the pointed tip is slightly bent, it can be easily straightened with pliers and reused, and should not effect engine performance whatsoever. It's a valve that regulates the amount of fuel that goes in the engine. The tip does not need to be centered with the hole in the main jet/nozzle (emulsion tube). Gas will still get around it. And over-tightening the needle in the main jet hole will crush the tip out of shape, making it difficult to regulate the fuel. If the tips is damaged from being overtightened, the high speed adjuster will need to be replaced.

A worn throttle shaft is the #1 cause of most engines wearing out and burning oil prematurely. If a carburetor has a worn throttle shaft, this will create a vacuum leak and the engine will idle poorly, if at all at times. Not to mention the engine will also draw in dirty air, causing wear on the valve faces/seats and piston rings, and engine will burn oil. More than .010" of play is considered too much for throttle shaft wear. Plus, at operating running speeds (3,600 RPM), the extra air will cause the engine to run lean on fuel, which will overheat the combustion chamber and cause the cylinder head to warp (blow a head gasket) and the piston and rings to wear prematurely, eventually resulting in severe engine wear and excessive oil burning. Along with regular maintenance, repair of a worn throttle shaft is required to help an engine last a long time. The most accurate way to check for amount of wear is with a dial indicator.

Furthermore, all Carter or Kohler and Walbro carburetors didn't come with a throttle shaft bushing installed from the factory. A new bushing (see below Ê) must be installed when the throttle shaft is worn and loose in the carburetor body, or sometimes a new bushing and a new throttle shaft both must be installed. If there's a counterbore (recession in the carburetor body) where the throttle shaft is, a short, flat bronze bushing can be installed, and if it's still in good condition, the original throttle shaft can be reused. But if there's no counterbore, the carburetor body will need to be precision aligned-bored for installation of a bronze sleeve bushing, and chances are, a new throttle shaft will also need to be installed. Special machining of the carburetor body is required for the sleeve bushing. And ALL Carter and Kohler #26, #28 and #30, and the older Walbro #52, #60 and #64 carburetors have the counterbore. Only the newer Walbro WHG #52, #60, #64, and the Chinese-made carburetors don't have the counterbore. If the carburetor has the counterbore, the throttle shaft will need to be removed, the dirt and debris will need to be cleaned out from the counterbore, and then the short, flat bushing can be installed. But if there's no counterbore, the upper hole in the carburetor body will need to be bored out in precision alignment with the lower hole in a milling machine, and then a bronze sleeve bushing can be installed.

Bronze Throttle Shaft Counterbore Bushing for all Carter or Kohler #26, #28, #30 and early Walbro WHG #52, #60, #64 carburetors with a counterbore that's used on Kohler K-series and early Magnum engine models K241/M10, K301/M12, K330/K331, K321/M14, K341/M16, K361 and KT17, KT17 Series II, KT19, KT19 Series II, MV16, M18, MV18, M20, MV20. All Carter and Kohler #26, #28 and #30 carburetors have the counterbore to accept this short, flat bronze throttle shaft bushing. If there's a [worn] rubber seal in the counterbore, this bushing will replace it. Dimensions: 1/4" i.d. x 7/16" o.d. x 1/8" height. NOTE: Apply clean motor oil or clean motor oil, gear oil or lubricating grease on throttle shaft before installing for smooth throttle operation and less wear to shaft, bushing or carburetor body.

OEM Kohler part # 25 158 02-S. $10.75 each, plus shipping & handling.
Installation Service: Install this throttle shaft bushing in your carburetor. $30.00 each for bushing, new screws and labor, plus return shipping & handling. Please contact me if you're interested in this repair service. An innovative concept by Brian Miller, because nobody else advertise this service.

Installation Instructions: The above È bushings makes contact with the upper unworn 1/8" portion of the throttle shaft. The original throttle shaft can be reused with the bushing if it isn't severely damaged. To install the bushing, first of all, to avoid breaking off the soft OEM brass throttle plate retaining screws, use a Dremel or equivalent small rotary grinder chucked with either a small grinding stone (chainsaw sharpening stone) or an 1/8" high speed steel end mill to grind away the flared threads at the end of the screws, then the screws can be removed, and then the shaft can be removed from the carburetor body. If the throttle (or choke) plate retaining screws breaks off, they can be successfully drilled out. Clean out the counterbore and depending on size of carburetor, slide the bushing on a 3/16" or 5mm screw (for the Carter #16, #18, #20, #22 carburetors) or a 1/4" or 6mm screw or bolt (for the Carter or Kohler #26, #28, #30 and early Walbro WHG #52, #60, #64 carburetors) and insert the screw or bolt in the counterbore hole (to align the bushing straight with the counterbore) and use small hammer or bench vise to drive- or press-in the bushing, and then reinstall the shaft.

Additional Note: Usually the short, flat bronze bushing will snug up a worn throttle shaft. With oil for lubrication, the bushing and shaft should last a long time. If the bushing fits somewhat loose in the counterbore, lightly tap the sides of the counterbore with a hammer to make the counterbore slightly oblong or egg-shaped. The newer Walbro's and the Chinese-made carburetors have no counterbore for the bushing, and sometimes in these carburetors, the [upper] throttle shaft hole will wear. When this happens, just installing a new shaft won't fix the problem. The upper hole must be precision-bored perfectly aligned with the [unworn] lower hole, and a bronze sleeve bushing will need to be installed along with a new throttle shaft. On other makes of carburetors, if the original shaft is worn and a new throttle shaft isn't available, then a new throttle shaft will need to be machined/fabricated. The throttle lever can be reused and welded to the new machined/fabricated shaft. And if necessary, a slightly oversized throttle shaft can be installed instead of the original diameter shaft. I can do all of these things for $50.00± each for parts and labor, plus return shipping & handling.

Bronze Throttle Shaft Sleeve Bushing for the newer Walbro WHG #52, #60, #64, and the Chinese-made carburetors that have no counterbore for the short throttle shaft bushing, or for the #26, #28 or #30 Carter or Kohler carburetors with a worn/enlarged counterbore for the short throttle shaft bushing. Not available from Kohler. Precision-made in the USA of compressed sintered bronze. Dimensions: 1/4" i.d. x .313" o.d. x 3/4" length. IMPORTANT NOTE: The upper throttle shaft hole must be precision-bored exactly to .3125" (5/16") in perfect center-alignment with the lower hole for installation of this sleeve bushing. The carburetor body will need to be clamped in a machine vise fastened on the table of a milling machine, aligned, and precision-drilled so the throttle shaft will rotate without binding after installation of the bushing. A drill press will not be accurate at all. If a drill press is used, the carburetor body could be ruined and rendered useless. Apply clean motor oil, gear oil or lubricating grease on throttle shaft before installing for smooth throttle operation and less wear to shaft and bushing. Not to be used in the Kohler-made carburetors for Kohler engine models K482, K532 or K582. An innovative concept by Brian Miller, because nobody else advertise the use of this part or this service.

Small Engine Remote Fuel Primer System Kits. Safe to use and works flawlessly! Can be used on most lawn & garden small engine equipment, garden pulling tractors, recreational vehicles, etc. With the fuel bowl atmospheric vent opening plugged (air passageway from inside the float bowl area to outside of carburetor), then with one or two pushes of the primer bulb, air pressure within the carburetor float bowl forces fuel through the main jet and out the nozzle, creating a slight flooding condition inside the carburetor throttle bore allowing a cold engine to start quicker. With this setup installed, the choke plate and shaft can be removed. No more binding of a mechanical cable-operated choke and/or bent choke plate, or messy and unsafe "hand choking" of the carburetor. The fuel baffle splash shield is not needed with this setup. For ordinary lawn and garden tractors, garden pulling tractors or virtually any small engine lawn and garden or snow removal equipment with a choke plate on the carburetor. Works with pump gas, race gas, E-85 or alcohol fuels. Requires 1/4" mounting hole. Kit includes primer bulb assembly w/serrated mounting nut and integrated 1/8" barbed hose fitting, 1/8" i.d. x 3/16" o.d. x 3' length clear vinyl hose, loop-type clamp and 1/8" diameter x 1" length brass tube. Click here for installation instructions. An ingenious, thoroughly researched and innovative concept by Brian Miller, because nobody else advertise this kit for lawn and garden tractors or various small engines.

NOTE: If an engine is hard to start, even with the choke plate fully closed and tuned correctly, then it may need a professional valve job performed and valve clearances reset. The reason some older engines is hard to start is because the valve faces, especially the intake valve, wears slightly away against the valve seat, and this causes the clearance between the valve stem and lifter to be lessened, which will prevent the valve(s) from fully closing to trap adequate compression in the combustion chamber [so the engine can start easier]. This remote fuel primer system will not fix this type of problem either. [Return to Previous Section, Paragraph or Website]

1-3/4" metal safety gas cap w/vent hole and neoprene rubber sealing material. Also has fuel baffle/splash shield and foam rubber (reticulated polyurethane foam) to absorb and prevent fuel from spewing out of vent hole due to normal engine vibration. OEM Briggs & Stratton part #'s 69221, 297866, 297866S, 392305, 393156, 395005. $9.00 each, plus shipping & handling.

FYI - If a gas cap is missing the gasket/splash shield, this part can be made by cutting out a piece of poster board material (cereal box, etc.) so it'll fit snug inside the gas cap. Be sure to make a small pin hole (1/16") off-center in the gasket for the atmospheric vent. If fuel spews out of the vent hole in the gas cap with a full tank of gas due to normal engine vibration and to prevent a possible fire, place a small piece of foam rubber (reticulated polyurethane foam) between the gasket and vent hole in the cap. The foam will absorb the fuel and block it from being forced out the vent hole, and it'll allow incoming air to pass through it as the fuel is depleted in the tank.

Governor Springs Ê | Top of Page

Throttle Stabilizer/Anti-Surge Springs. Lightweight spring connects between throttle and governor levers to remove free play (looseness) in linkage connections and reduce erratic engine behavior due to throttle flutter for a smoother running engine and reduce wear to throttle shaft. Can be used on virtually any Briggs & Stratton, Kohler K-series, Magnum or Command single- or twin-cylinder cast iron or aluminum block engine. A must for a generator, welder or 4,000 RPM± governored competition pulling engine. With a governored pulling engine, throttle flutter causes the engine RPM to momentarily spike, which will cause the rear tires to lose traction (temporary jerk), resulting in a possible failed pull. If a small hole isn't already present in each lever close to linkage connection, may need to drill a small hole to install spring.

OEM Kohler part # 25 112 17-S. $5.33 each, plus shipping & handling.
Governor Cross Shaft Bushings with or without a snug-fitting neoprene rubber O-ring or rubber lip oil seal installed in machined counterbore to prevent dust and dirt/debris from wearing the bushing and/or shaft and prevent messy film of oil on outside of engine. Seal fits snug in bushing and on shaft, and has no effect with operation of governor whatsoever. For Kohler engine models listed below Ê with bushing # 230476-S, 41 158 02-S or 235476-S. FYI - Vacuum within engine crankcase created by the upward stroke of the piston draws in dust, dirt/debris through the bushing and pressure created by the downward stroke of the piston blows out a fine mist of oil through the bushing. In overtime, an oily mess builds up on the outside of the engine. NOTE: When ordering, please specify part number of bushing or engine model and specification numbers. And before installing bushing, apply clean motor oil, gear oil or lubricating grease on shaft for smooth throttle action and less wear to bushing, shaft and seal.

Low Pressure 12 Volt Fuel Pump Installation Kits. Low pressure, small and compact. Convert from gravity feed, or replace faulty vacuum-operated/pulse fuel pump or mechanical fuel pump (with a deteriorated diaphragm that can seep gas into the crankcase, diluting the oil, which can could severe internal engine damage), or upgrade to one of these pumps for more fuel delivery. Each produces 2.5-4.5 psi @ 30 gph, and is non-adjustable. Fuel regulator is not required, but may require one under certain conditions. Use for general lawn and garden work, or for garden tractor pulling. Will work for most single- and twin-cylinder gas engines such as Kohler, Briggs & Stratton, Tecumseh, Wisconsin, etc., on virtually all models of Cub Cadet, John Deere, Wheel Horse, Sears Suburban, Massey Ferguson, and just about any lawn & garden equipment with a 12 volt electrical system. These electric fuel pump kits come with fittings that accepts 1/4" i.d. fuel hose, the same size that's on most Kohler and other makes and models of engines. If it's a Kohler AQS (Quiet Line) engine, the fitting in the carburetor would need to be changed to 1/4". If the engine has magneto or solid state electronic ignition, but no charging system, and only a 12 volt battery is used to power the fuel pump, the battery will need to be recharged with portable battery charger every now and then so the fuel pump will work at peak efficiency. Alcohol resistant and very durable. For stock engines or engines running at high RPM or wide open throttle. Suitable for small gas engines up to 4 cylinder carbureted engines. Instant fuel prime to the carburetor as soon as pump is powered up. Ideal when equipment runs out of gas and no need to crank engine for a long time to refill carburetor to restart engine. Saves on starter motor wear. Each operates on 12 volts DC. Rather than a motor or diaphragm, these solenoid pumps use a piston actuated by an electromagnetic coil to generate fuel pressure and flow. By using only short pulses of electricity, this pump is very efficient. IMPORTANT: For long term storage, drain and flush out all fuel, leave fuel hoses disconnected so entire fuel system can "air dry," and apply WD-40 or light oil in the fuel pump to prevent oxidation, which could cause the moving parts to "freeze up" or stick. For a pulling tractor, if methanol fuel is subject to a water test, don't add WD-40 or oil in the pump. Just drain and flush out all fuel, use compressed air to remove any remaining fuel from the pump, and store the tractor in a cool, dry environment. Wire Connections: The BLACK wire connects to negative (–) ground (tractor chassis or frame), and the RED wire connects to the positive (+) battery post or a terminal on the ignition switch that connects to the positive (+) battery post. If the wires are connected in reverse, the fuel pump will pump fuel in the opposite direction. It will not harm the pump. And the filter connects on the side closest to the fuel tank to help keep the inside of the pump clean so it will last longer. NOTE: Electric fuel pumps listed here come with a one year warranty. Install the inline fuel filter before the pump (inlet port) to prevent any debris from becoming lodged in the pumping mechanism. If there is debris lodged, it may be removed with 150 psi compressed air when applied in the reverse direction of fuel flow. If the pump still won't work right after clearing it out, please remove the fittings, return the pump and I'll send you another new fuel pump without the hardware and fittings.

Professional Carburetor Rebuilding Service - Top of page | Please contact me if you're interested in any of these parts or services.

FYI: I can professionally rebuild older vintage and antique carburetors virtually of any kind as well as newer ones, as long as replacement parts are available. I also have the capability to fabricate new throttle and choke shafts. Please contact me if you have any questions.

Rebuild and/or Repair YOUR 10hp-18hp Carter or Kohler or Walbro Carburetor. Basic rebuild with no "high performance" modifications whatsoever, according to the condition of the carburetor, the minimum rebuild cost is $35.00 for thorough cleaning of the carburetor, install overhaul/rebuild kit and labor. This includes the parts and services it may need that's listed below. Anything else it may need will be an additional charge. FYI - Many of my customers send me their carburetors for rebuilding, but lots of times I couldn't find anything wrong them. So I'd call my customers just before returning their carburetor asking how their engine acted. And after hearing their story, I told them that their engines might need a valve job performed instead. And lo and behold! Many of them either adjusted the valves or had a professional valve job performed and said that their engines ran like new. This doesn't happens with all older engines, only the majority of them.

When I rebuild a carburetor, I completely disassemble the carburetor, including the choke and/or throttle shafts if they're worn. I resurface the each mounting flange on the carburetor on my wide, flat belt- or disc-sander to remove any roughness/warpage and restore flatness to prevent a vacuum leak, then I place all the parts in my ultrasonic cleaning machine (with automotive windshield washer cleaning fluid and high quality and non-corrosive laundry detergent for more thorough cleaning) for about 5 minutes. I take the parts out, use 150 psi compressed air to blow-dry all the parts, then I inspect each part for wear or any previous damage and repair or replace the damaged part(s) and replace the worn parts with new parts. I also install a new bushing foam rubber seal (to prevent dust and dirt from entering past bushing/throttle) for the throttle shaft, and a new carburetor overhaul/rebuild kit. I enlarge the lower hole on the high speed needle adjuster so engine will start quicker and idle better. And I repair any stripped threads in the carburetor body for the air cleaner/filter mounting base. And the only way to remove all the paint from the carburetor body is to sandblast it. But sandblasting can allow tiny particles of sand to become embedded in the fuel passageways, which could break loose and cause problems later. Therefore, I do not sandblast carburetors. An original, ingenious and innovative concept by Brian Miller, because nobody else advertise this repair service.

"Old School" Technology High Performance Stock-Appearing Carburetor Modifications - bore-out and rework YOUR #26, #28 or #30 Carter or Kohler carburetor for use with Gas, E85 or Methanol fuels. Carburetor is modified internally to improve engine performance. $85.00 labor, plus return shipping & handling. Extra charge if any parts are needed. Work includes what's listed above È plus whatever parts and services it may need that's listed below.

ü Bore venturi to a limit of .995" or 1", straight-through design (to match the diameter of throttle bore) or whatever your club's sanctioning rules allow. NOTE: Read your rules carefully to make sure! I'll need a copy of your club's sanctioning rules regarding the legality of the carburetor, so when I rework it, it'll be legal for use in the class you plan to pull in. The venturi in a Chinese-made Kohler-replicated #26 carburetor can be bored out to is 1.09" or 1-7/64", the same diameter as the throttle bore. But the maximum the venturi in a Chinese-made Kohler-replicated #30 carburetor (which actually has a throttle bore diameter of 29.76mm / 1.17") can be bored-out to is 1". If it's bored-out any bigger centered of the throttle bore, being the #26 and #30 are cast in the same mold and machined the same externally, the boring process will likely break through where the fuel inlet port is, rendering carburetor body useless. But the OEM Kohler #30 carburetor can be bored out to 1.2", the same as the throttle bore, with no risk of breaking into the fuel inlet port. A bored-out venturi and reworked carburetor is when the carburetor is modified for maximum performance for general yard and garden use, and/or for competition pulling.
ü If needed, drill out main jet/nozzle so venturi can be bored: $35.00 extra. Price includes new main jet/nozzle.
ü Eliminate choke shaft and plate and plug shaft holes. If your rules require a working choke or if you would like to have a working choke, please let me know and I will not remove it.
ü Eliminate choke shaft and plate, and convert carburetor for use with the remote fuel primer system kit. $20.00 extra for labor and kit. An ingenious and innovative concept by Brian Miller, because nobody else advertise this kit.
ü Convert to bottom main fuel adjuster: $17.00 extra.
ü Convert your carburetor for use with E85 or methanol fuels with the high-performance modifications: No extra charge.
ü Missing, worn beyond specifications or broken parts are extra charge.

NEW fully adjustable Kohler #26 and #30 carburetors bored-out and reworked for high performance use.

FYI - For the air cleaner assembly on the Kohler K90/91 engine to the right, I used Tecumseh part #'s 35065 (mounting adapter), 35797 (twist-on cover) and 35066 (air filter). Although the Tecumseh air cleaner assembly, part # 730164, will also work with no modifications. For the one shown to the right, I bored the center of the air cleaner mounting adapter so it will match the choke opening in the carburetor to allow the engine to draw plenty of air. I also used 2 small spacers with flat washers and 8-32 UNF screws with flat washers and lock washers to securely mount the adapter to the Carter Model N carburetor.

NOTE: If possible, apply clean lubricating grease on the hinge pin before installing points so the hole will last longer. If it's dry, it'll wear over time, effecting ignition timing, resulting in loss of engine power.

Hex Socket (Allen) Head Cap Screw w/split lock washer to replace OEM Kohler slotted or Phillips head adjustment/clamp screw in Kohler/aftermarket points for easier access with a 9/64" hex (Allen) L-wrench (below Ê) to precisely set ignition timing with less effort in hard-to-reach places in small engine equipment when the engine sits lengthways (such as Cub Cadet) and securely tighten screw so points will not slip out of adjustment. NOTE: For aftermarket points, the threads may need to be recut with a 8-32 UNF hand tap. And due to risk of stripping threads in points bracket, do not over-tighten this adjustment screw! No extra charge to install hex socket screw in purchased points. An original, ingenious and innovative concept by Brian Miller. Please accept no other advertised copycat products of this kind.

$1.00 each, plus shipping & handling.

Adjustable Chevy Ignition Points with Stiff Spring for Quick Reaction at High Engine RPMs. These points can be easily adapted for use on Kohler [pulling] engines with an adapter bracket for easy adjustment of the ignition timing with a hex key (Allen) wrench. Use with a minimum 3.0 ohm ignition coil to prevent premature burning of points contacts. Due to the inability to completely seal (cover) the ignition points contacts from dust, dirt and debris, these are for competition pulling only, and not for ordinary lawn & garden equipment. And being the bracket for the Chevy points and the Chevy points themselves are much larger than OEM Kohler points and bracket, the OEM Kohler points cover will not fit over the Chevy points and mounting bracket.

NOTE: The use of resistor type spark plugs shortens the life of most small engine magneto or solid state electronic ignition coils. Therefore, it's best to use a new high quality spark plug with a Copper Core/Non-Resistor gapped at .025" for single cylinder and V-twin engines, and .015" each for opposed twin cylinder engines to prevent overheating of secondary windings within the coil and possibly causing premature coil failure. Set the laminations to the flywheel magnet clearance (air gap) at .010". And the easiest and most accurate way to set the air gap is to use a business card, poster board, or part of the box the new coil came in. These measure about .010" thickness. Place a strip of the paper or box between the coil's laminations and magnet in the flywheel and allow the magnet to pull the laminations to it, then tighten the coil mounting screws securely.

Self-Energizing Solid State Electronic Ignition Coils with molded-in Module. FYI - All self-energizing solid state electronic ignition coils/modules require a grounding-type [OFF/ON toggle] kill switch to short circuit the primary windings in the coil to shut off the engine. They do not need 12 volts of power because this will instantly burn up the coil. And save the spark plug wire off the defective coil. It has a metal core, and with a battery coil terminal and rubber boot installed, it can be used in a battery-powered ignition system.

Self-Energizing Magneto Ignition Coil. Fits all Kohler engine models K91 with magneto ignition. Spark plug wire (not included) inserts into coil. 15,000± volts output. NOTE: Usually, the point gap sets at .020", but sometimes it will need to be set as close as .015" just to get a spark. This coil will work better when used with a Universal Solid State Electronic Ignition Module (see below ). The short wire on the coil is for ground, the longer wire connects to the ignition points and condenser/capacitor or Universal Solid State Electronic Ignition Module, and may need to be made longer depending on your application. Dimensions: .500" x .500" square hole (across flats) x 1.700" o.d. x 1.080" length. When installing, the coil must fit snug on the laminations to receive the full effect of the magnetic field through the stator from the rotating magnet(s) to fully energize the windings to create a strong spark. If the laminations on your stator are too big for the hole in this coil, they can be ground or filed smaller so the coil will fit snug, then bend one laminate over to retain the coil. Or if the laminations are too small, thin strip(s) of steel can be added as shim(s) so the coil will fit snug. (Sometimes one must make changes for a replacement part to work.) Do not attempt to enlarge the hole in the coil! How magneto coils produce a spark. NOTE: Magneto ignition system can be upgraded with the electronic transistorized ignition module (below) for a stronger and more stable spark, quicker starts, and virtually trouble- and maintenance-free ignition system.

NOTE: The magneto coil wrapped with varnish-coated paper (Kohler part # 210293), and the ignition stator assembly and ring shown above È are Discontinued from Kohler. If you have an engine without these parts and you can't locate them from any source, your only option is to convert the engine to the battery-powered ignition system. A small motorcycle battery or a rechargeable 12 volt sealed lead acid (SLA) battery with a minimum 4AH (Amp Hour) rating will need to be required to power the ignition, and with no charging system, a portable battery charger will need to be used to keep the battery fully charged when the tractor is not in use so the ignition will produce a strong spark. Avoid using a high-output/performance coil because these draw more power from the battery.

Replace the Points and Condenser in a Magneto Ignition System with a Universal Solid State Electronic Ignition Module -

Designed for self-energizing magneto ignition systems only. Will NOT work with battery-powered ignition systems.
Upgrade the magneto ignition system on virtually any engine with the latest technology! Do away with the ignition points and condenser/capacitor, and install a solid state electronic ignition module. It should be the end of your ignition problems. The ignition points and condenser/capacitor is not to be connected to the coil or module. They need to be removed from the engine and plug the ignition points pushrod hole (Briggs & Stratton or Kohler engines).
Universal and high performance. Improves engine performance by producing a strong spark, and by stabilizing the spark, much like my custom-made crank-trigger and flywheel-trigger electronic ignition does, except the detectable target is the magnets on or underneath the flywheel and the coil laminations. This module has a durable die-cast aluminum housing. Weather-proof and very reliable. Ignition timing is automatically set. No kick-back and no timing adjustment required. Works excellent with virtually any magneto ignition coil!
Suitable for use with most 2 leg or 3 leg magneto coils and with a flywheel having one or two magnets mounted internally or externally, and with coil mounted underneath or outside of flywheel. Works great regardless of the polarity of the magnets, too. Works on most lawn mowers, chain saws, trimmers, garden tillers, snow throwers, brush cutters, various one or two cylinder outboard boat motors, etc., with ignition points and condenser/capacitor ignition. But will not work with most Stihl trimmers and chain saws, or when the ignition coil is energized by a generator that gets its power from the magnet in the flywheel, such as various outboard boat motors. Usually, the coil don't need replacing when substituting the ignition points and condenser/capacitor with one of these solid state electronic ignition modules. If the engine ran, then the coil is obviously good.
Works only with magneto type ignition coils originally connected to contact ignition points and a condenser/capacitor. They will not work with solid state electronic ignition (CDI) coils, battery ignition coils or with flywheels having a ring of magnets mounted internally to which the ignition coil (mounted underneath flywheel also) operates off of, such as the bigger aluminum block Tecumseh engines (8hp and up). Engines can't start under full compression and with advanced ignition timing. One or the other must be "suppressed" in order for the engine to crank over without "kicking back" to start. Either it needs to have an automatic compression release to relieve about half the compression, then the compression will return to full upon start up, or the timing needs to be positioned at TDC, then it can automatically advance upon start up. (With the module, as each magnet pass the coil, it'll produce a spark. And if the spark don't occur at the precise time with the piston at a certain position in the cylinder, the engine will either "kick back" or will not run.) "Kick back" occurs when the crankshaft/flywheel suddenly and violently rebounds or rotates in the opposite direction, which is could bend or break the starter armature shaft or the aluminum starter housing. If the magnets for the charging system won't interfere with the magneto coil(s), then these modules should work well. But if the magneto coil(s) operate off the same magnets for the charging system, then neither module won't work. The modules senses when the magnet pass the coil and that's when it makes the spark. If a bunch of magnets continually pass the coil, then the coil will produce an array of sparks.
How the timing is automatically set and how it works: First of all, with ignition points, the point gap determines where the ignition timing is set (on systems with a fixed or non-adjustable ignition coil). Therefore, the spark occurs when the magnet in the flywheel pass the coil laminations the moment the ignition points open. But with no ignition points, the magnet still pass the coil laminations at the same moment, which sends an electrical current through a transistor and electronic components within these modules. This current is sent in the form of a signal to the module; within, a transistor opens the primary circuit in the coil and the spark occurs. All this happens at the speed of electricity, which can be anywhere from about 50% to 99% of the speed of light, depending upon the quality of the electronic components and wire connections. Either module provides unlimited RPM. The conventional ignition points and condenser/capacitor ignition system is less responsive.
This module should work very well with most magneto ignition coils. However, a new coil is recommended to use with this module. If a used coil is utilized, a weak spark may occur. This module is not for use on engines equipped with battery ignition, solid state electronic ignition coil/module or multiple magnets under the flywheel with ignition coil under the flywheel, too.

Two Wire Semiconductor Rectifier Zener Diodes. Either can be used as a rectifier in a small engine 3 amp/12 volt non-regulated stator alternator charging system to convert alternating current (AC) to direct current (DC) to recharge the battery, power LED lights and/or low-amperage electrical accessories. Not needed to power filament lights or an electric PTO clutch. Or can be used to excite or energize the field windings in a belt-driven automotive alternator or direct-drive 120/240 AC volt portable generator when powered by a small engine so alternator/generator will produce electricity as soon as the engine starts.

FYI - Briggs & Stratton engines have either one or two OEM alternator stators and they are joined together in two half circles under the flywheel. Some engines only come with one half stator. Each half produce 3 amps of power & 14 volts @ 3,600 RPM. If an engine comes with two stators joined together, one half produces AC, which is used to power the lights and electric PTO clutch. And the other half also produce AC, but is connected to a minimum 3 amp/14 volt diode, which is used to only recharge the battery. Under normal yard use, 3 amps is not enough to overcharge and burn up the battery. If both stator halves are wired together from the factory (as they are on certain engines), they will produce 6 amps of AC power and a 6 amp solid state electronic voltage rectifier/regulator is used to power the lights, electric PTO clutch and recharge the battery.

AC Voltage Meter/Monitor. Designed to plug into any 120 volt wall receptacle/outlet, house backup generator or portable [RV] generator or welder to provide an accurate reading of the AC line voltage. Use this meter to set the engine governored speed so generator/welder will produce 120 volts of continuous power to prevent from under-powering or over-powering electrical equipment.

High Quality Standard-Size 12 Volt Canister-Type Oil-Filled Ignition Coils. Either coil below can be used on various makes and models of small engines (Kohler, Tecumseh, etc.) with ignition points and condenser, Dynatek Dyna S, Pertronix Ignitor or A-1 Miller's custom crank-trigger and flywheel-trigger electronic ignition systems. NOTE: Most failures of battery ignition coils is caused by overcharging of the electrical system due to a defective solid state electronic voltage rectifier/regulator or defective [automotive] battery. Or the use of aged and deteriorated suppression/carbon-core spark plug wire and/or an old resistor type spark plug will also cause a good coil to eventually fail because the secondary windings within the coil must build up more voltage, which cause the windings to overheat and eventually burn up from producing excessive voltage to fire the plug. Therefore, if it's not already equipped, it's best to install an ammeter/amp gauge to monitor the charging system.

New 1.6 Ohm Ballast Resistor for use with any 12 volt ignition coil not having an internal resistor (above È) to prevent excessive burning of points contacts, or use with the Chrysler / Dodge / Plymouth electronic ignition control module/unit, or connect with coil having a minimum 1.4 ohm internal primary resistor to prevent burning up the Dynatek Dyna S or PerTronix Ignitor electronic ignition control modules. Install between the coil positive (+) terminal and wire coming from the ignition switch to the coil. This will allow the points to possibly last the life of the engine. NOTE: Ignition resistors with a higher ohms value are known as "Point Savers." The higher the ohms resistance in an ignition coil or a ballast resistor has, the longer the ignition points will last (as long as the points are installed clean, and doesn't become contaminated with dust, oil, water, etc.). Any 12 volt ignition coil with an 3+ ohm internal primary resistor connected to a minimum 1.6 ohm ballast resistor when used in a points and condenser/capacitor ignition system will allow the points to possibly last the life of the engine. Because the increased resistance allows a very low current/voltage to pass through the contacts in the points. Also, a suppression/carbon-core spark plug wire and resistor type spark plug shouldn't be used in this system due to overheating of the ignition coil. Therefore, it's best that a high temperature metal core spark plug wire and Copper Core/Non-Resistor spark plug be used. The ignition system will still produce a strong spark because an average small engine requires only a fraction of voltage from the coil. This is best to used with general lawn and garden, snow removal, etc., and not for competitive pulling. Therefore, if it's not already equipped, it's best to install an ammeter/amp gauge to monitor the charging system.

Complete Battery-Powered Ignition Conversion Kits - When Kohler's OEM magneto or Breakerless Ignition fails, the engine can be converted to a battery-powered ignition system. Battery-powered ignition systems last longer, produces a stronger spark, and when a part goes bad, it doesn't cost much to replace. It's a reliable, simple design and there's no guesswork about it. FYI: Battery-powered ignition conversion kits are intended mainly for various older engines when the OEM magneto or Breakerless Ignition no longer produce a spark, replacement parts are not available or are very expensive (cost prohibitive). Also, the most hassle when using battery-powered ignition without a charging system integrated with the engine to recharge the battery is the use of a remote battery charger. And eventually a new battery will need to be purchased, because they only last a few years. For a battery to power the ignition, a small, lightweight and rechargeable 12 volt sealed lead acid (SLA) battery with a minimum 4Ah (Amp Hour) rating or a small motorcycle battery can be used. Click here for battery-powered ignition wiring diagrams.

Personally, I had a John Deere 110 with a K181 Kohler engine with magneto ignition and a 10 amp alternator charging system in my shop for repairs. The engine would start right up and idle well, but not accelerate. I tried a new Autolite 295 copper core spark plug gapped at .025", new magneto ignition coil, different flywheels, different stator, engine ran the same way, no matter what. It liked to drive me nuts! So I had no choice but to remove the magneto coil and I converted the engine to battery ignition with a new 12 volt 3.0 ohm compact-size epoxy-encapsulated ignition coil, rewired the ignition switch and the engine accelerated with no problem. And being the 110 has a compact engine compartment, I had to fasten the small size coil on the carburetor side of the flywheel shroud with a couple of spacers and 10-24 UNC screws with matching nuts (3/8" wrench size) welded to the inside of the flywheel shroud. I reused the same small condenser and ignition points with this small coil. Although an OFF/ON toggle switch can be used to power this ignition, and being the OEM magneto ignition/start key switch will not work with battery ignition, I chose to use a battery ignition/start key switch and rearrange the slide-on spade connectors in the plastic connector housing for this type of switch to work in the tractor. See the picture to the right of this setup. And if you're having a similar ignition problem, and if you're interested, I offer a new 12 volt 3.5 ohm compact-size epoxy-encapsulated ignition coil that can be used to convert the ignition system for your tractor. I also offer a complete ignition conversion kit below. - Brian Miller

Single Cylinder (Flathead) Engines - Convert from Magneto Ignition to Battery-Powered Ignition. Convert virtually any single cylinder, air-cooled cast iron or various aluminum block small gas engine, such as Kohler, Tecumseh, Briggs & Stratton, Clinton, etc., that originally came with a magneto ignition system (having ignition points, condenser/capacitor and ignition coil that has voltage generated by a permanent magnet in the flywheel, instead of being powered by a battery or a self-generating charging coil) into a battery-powered ignition system. NOTE: Must use a universal automotive start/ignition key switch, or a push-button switch to crank the engine with an OFF/ON toggle or key switch to power the ignition. Reuse existing ignition points, but set gap at .020" or set ignition timing at 20º BTDC, and reuse same type of spark plug, but set gap at .035" for a stronger spark. See wiring diagram below Ê.

Ignition Kit with compact-size epoxy-encapsulated ignition coil. Use this kit when there is not enough space on the engine or tractor for a full-size 12 volt canister ignition coil. Kit includes: New 12 volt 3.5 ohm compact-size epoxy-encapsulated ignition coil w/mounting bracket and molded-in 11" length metal core spark plug wire w/90º boot/terminal (set spark plug gap at .030" with this coil), new condenser/capacitor, new ignition points and new 22" length 16 gauge coil-to-ignition points wire w/grommet and terminals.

Ignition Kits to Convert from Breakerless Ignition to Battery-Powered Ignition with Points and Condenser for Kohler engine models K181, K241, K301 or K321. (K341 and K361 engines originally did not come with Breakerless Ignition.) Instead of replacing defective cost-prohibitive Breakerless Ignition components, convert your engine to the inexpensive, low-cost and reliable ignition points and condenser/capacitor ignition. Kit includes: new 3.0 ohm ignition coil w/mounting bracket, new ignition points, new condenser/capacitor, 22" length 16 gauge coil-to-ignition points wire w/grommet and terminals, ignition points pushrod, ignition points cover, ignition points cover gasket and four 10-24 UNC (coarse thread) screws. Use the same OEM Kohler spark plug wire and ignition switch that came with the tractor or equipment. NOTE: Use a pointed #6 self-tapping sheet metal or drywall screw and a mini nail puller pry bar to remove the brass block-off plug from ignition points pushrod hole. Do not force the screw into the plug or the plug could go inside the crankcase! Just gently thread it in a few threads, that's all it takes to pull the plug out. But if the engine block has a Briggs & Stratton ignition points plunger plug, the plug can be removed by using a mini nail puller pry bar as well. May need to use a hammer to drive the wedge under the head of the plug to get a good grip on it to pull it out. And if there seems to be no movement for opening and closing of the ignition points, there may be some metal flashing blocking the ignition points pushrod hole where the factory didn't drill all the through the hole. Because all Kohler engines with Breakerless Ignition have the camshaft with the ignition points lobe. Only the Magnum engines have the cam without the ignition points lobe. After this is remedied, set ignition points gap at .020" or better yet, set ignition timing at 20º BTDC, and reuse same type of spark plug. See wiring diagram below Ê. IMPORTANT: The wire that comes from the stator under the flywheel for Kohler Trigger Module or Tecumseh Solid State Ignition Module generates about 250 volts (serious) while the engine is running at full governored speed. Do not touch this wire (terminal) with one bare hand and the engine itself with your other hand while the engine is running! It is not needed for any of my custom-made crank-trigger and flywheel-trigger electronic ignition systems. So snip off this wire or tape up the terminal to prevent a short circuit or electrocution.

100% Maintenance-Free Custom Electronic Ignition Systems That Operate Off the PTO End of a Competition Pulling Small Engine - Eliminates Points and Condenser

100% Digital Crank-Trigger Ignition Kits with Self-Contained Dynatek Dyna S or PerTronix Ignitor Sensor/Modules for Single- or Opposed Twin-Cylinder Engines - (Updated 12/9/17)

A new way to revolutionize the ignition system on virtually any small gas engine! Virtually trouble- and maintenance-free, and water-proof. These ignition modules/sensors is a small, lightweight, compact and completely self-contained electronic ignition system built with the latest state-of-the-art engineering with the use of microelectronics. Fits entirely on the engine block; no ignition box and additional wiring to clutter the engine compartment because the electronic ignition control module and pickup coil/sensor are contained in the same sealed casing. The Dynatek Dyna S and PerTronix Ignitor sensor/modules will allow the engine to idle smoothly and accelerate to its full potential with no hesitation or misfire.

The Dynatek Dyna S sensor/module operates on 12-1/2 to 15 volts negative ground, and requires an ignition coil with a minimum 3.0 ohm internal primary resistor to prevent from burning up the module. And the PerTronix Ignitor sensor/module operates on 8 to 15 volts negative ground, and also require an ignition coil with a minimum 3.0 ohm resistor. Using a coil with either sensor/module with less than total of 3.0 ohms of primary resistance for a long period of time will cause them to overheat and the engine may misfire until it cools down, or the sensor/module might fail prematurely. A metal core conductor spark plug wire, and Copper Core/Non-Resistor spark plug should be used. If the voltage drops below the minimum requirement for either sensor/module, the engine may idle well, but not accelerate, or the engine may run erratic. Either module/sensor can be used with a standard-output/stock or high-output/performance ignition coil, as long as the coil has a 3.0 ohm internal primary resistor, or a ballast resistor is connected that totals 3.0 ohms of resistance. These sensor/modules should not be used with magneto-type ignition coils, being magneto coils have a 1.0 ohm internal primary resistor. A metal core spark plug wire can be used with either sensor/module.

These maintenance-free crank-trigger electronic ignition setups have been thoroughly tested and proven very reliable for general lawn and work, and all classes of single and twin cylinder competition pulling engines. One sensor/module is needed for an opposed twin cylinder engine, and two modules/sensors spaced precisely at 90º apart are required for V-twin engines. These are the same ignition used by professional pullers everywhere. Reliable at high RPMs, the Dynatek Dyna S or PerTronix Ignitor modules provides unlimited RPM. They will allow the ignition system to operate at the speed of electricity, which can be anywhere from about 50% to 99% of the speed of light, depending upon the quality of the electronic components and wire connections.

Spark occurs when a small and super strong rare earth/neodymium ring magnet embedded in an aluminum locking set screw collar, which is much like an automotive reluctor ring, that's fastened on the crankshaft's PTO end pass the sensor/module. (Rare earth and neodymium magnets are the strongest available. Five times stronger than ceramic (ferrite) magnets for a stronger detection.) Either sensor/module packs a lot of punch and allows the ignition system operate at 100% efficiency for a stronger spark.

Dynatek Dyna S and PerTronix Ignitor Maintenance-Free Crank-Trigger Electronic Ignition Installation Instructions -

Our universal flat mounting plate can be adapted for use on various makes and models of one or two cylinder (twin opposing cylinders) engines by drilling new mounting holes. And being there are so many different bolt patterns on the PTO end of Kohler and other makes and models of engines, these are not a simple "one kit fits all" bolt-on ignition kit. Therefore, customer will need to locate and drill holes in the mounting plate in alignment with the bolt holes on the PTO end of the engine block. If there are no bolt hole(s) on the PTO end of the block, they will need to be drilled and tapped. Minimum of 1/4" bolts can be used. Locate and drill (machine) slotted adjustment holes in the mounting plate, fasten plate to PTO end of engine block. And then drill and cut 4-40 NC threads in the mounting plate for positioning/clearance of the sensor/module clearance to the locking set screw collar w/embedded rare earth magnet. Additional spacing of modules/sensor may be required so magnet will be aligned with the center of the sensor on various applications. Air gap/clearance between the sensor/module and locking set screw collar w/embedded rare earth magnet is .010"-.060". Sensor/module may not operate or engine may misfire if gap is wider than .060". When mounting the GM 4-pin HEI module, always fasten it with dielectric, thermal or heat sink grease/paste on a clean, flat aluminum plate with plenty of fresh air circulation to dissipate the heat while in operation. NOTE: Do not allow sensor/module to make contact with locking set screw collar w/embedded rare earth magnet while engine is running!

NOTE: The Dynatek Dyna S and PerTronix Ignitor crank-trigger ignition kits with the locking set screw collar w/target magnet or screw (just below Ê) installs and operate off the PTO end of the engine block, and is intended for competition pulling only. The set screw collar is specifically for competition pulling engines, because these engines have nothing on the PTO end of the crankshaft, such as a clutch assembly. The set screw collar can't work on the flywheel end because there's no place to mount it. Click HERE for Custom electronic ignition kits that operates off the flywheel end of the engine. These can be used for stock competition pulling engines and/or ordinary lawn & garden engines.

Wiring Directions for Either Module Shown Below: Connect the BLACK wire on module to the negative (–) terminal on the ignition coil (and to nothing else), and connect the RED wire on the module to the positive (+) terminal on the coil and to the ignition switch (positive (+) battery post). Do not connect the wires in reverse or the module will burn up instantly when power is supplied!

Designed Specifically for Single Cylinder Garden Pulling Tractors, these Self-Contained 12 Volt High Performance Dyna S or Pertronix Ignitor Ignition Kits are Integrated with a Durable 3.0 Ohm High Energy Ignition Coil Are Built with the Latest State-of-the-Art Engineering. Thoroughly tested and proven to be very reliable. Self-contained and very compact. Each kit includes: Sensor/module, coil, bracket and locking set screw collar w/embedded detector/target magnet. No need for a separate/remote-mounted ignition coil and additional wiring. Unlike the advertised competition, these module/sensor and coil ignition kits are fastened to a sturdy aluminum plate which mounts on the PTO end of the engine block. Customer may have to drill and tap the block to mount the crank trigger or modify the bracket if necessary. Each ignition kit comes prewired with one or two simple wire connection(s): Connect the RED wire to the ignition switch (battery positive (+) post, and connect the BLACK wire to the self-grounding killswitch (if equipped), or snip off the black wire if not needed. IMPORTANT: Do not connect the wires in reverse or sensor/module will burn up instantly when power is supplied! And the module will burn up if the ignition switch is left on for more than 5 minutes with the engine not running. So to prevent this from happening (accidentally), for 100% assurance, install a high amperage main disconnect/cutoff switch that kills the power to everything on the equipment, or install a bright (LED) indicator light that illuminates when the ignition switch is on, or install an illuminated (lighted) OFF/ON toggle switch for the ignition. Set the air gap/clearance between sensor and magnet in locking set screw collar at .010"-.060", and set spark plug gap at .035". Please specify diameter of crankshaft PTO end for locking set screw collar w/embedded rare earth magnet. Most common crankshaft PTO end diameters are 1" and 1-1/8", but 3/4", 1-1/4", 1-3/8", 1-7/16" and 1-1/2" are rare. Most billet steel crankshafts have a 1-1/2" diameter PTO end (raised shoulder). Please specify diameter of crankshaft PTO end for locking set screw collar w/embedded rare earth magnet. Made in USA. Picture and video of each product coming soon.

Most common crankshaft PTO end diameters are 1" and 1-1/8", but 3/4", 1-1/4", 1-3/8", 1-7/16" and 1-1/2" are rare. Most billet steel crankshafts have a 1-1/2" diameter PTO end (raised shoulder). Other sizes available. $15.00 each, plus shipping & handling.

How to Check for Spark and Set the Timing for the Dynatek Dyna S and PerTronix Ignitor module/sensors - After either setup is installed on the engine and power is supplied, simply rotate the locking set screw collar w/embedded rare earth magnet (loose) on the crankshaft back and forth by hand. Each time the embedded detector/trigger magnet pass the sensor/module, spark should occur. NOTE: Do not use a battery charger alone to perform this test. Battery chargers constantly switch between high and low voltage at 60 cycles per second, and the module sees this as the ignition being switched on and off resulting in a continuous, constant array of sparks.

The simple way to set the ignition timing STATICALLY (engine not running) for either sensor/module -

Rotate the crankshaft by hand to align the timing marks or timing tape on flywheel or starter pulley with the pointer to set the timing where it needs to be.
With the locking set screw collar w/embedded rare earth magnet loose on the crankshaft, rotate the ring by hand to align the magnet with the center of the sensor/module.
Securely tighten the Allen set screw and the engine can now be started.

How to accurately set the ignition timing STATICALLY for the Dynatek Dyna S, PerTronix Ignitor and Inductive 3-Wire Proximity Sensor/Module - (This is also how to test if the sensor/modules or the ignition system is functioning or not.)

Connect the wires correctly for either sensor/module as specified above with a fully charged 12 volt battery connected in the circuit. NOTE: Do not use a battery charger alone to perform this test. Battery chargers constantly switch between high and low voltage at 60 cycles per second, and the module sees this as the ignition being switched on and off resulting in a continuous, constant array of sparks.
Connect a battery-powered test light or multimeter [set on the 12 volt reading] between the negative (–) coil terminal and engine/chassis ground.
- For the non-magnetic Dyna S or Ignitor modules and inductive 3-wire proximity sensor, with the magnet in the locking set screw collar not centered or aligned with the sensor in the module, the light should be off or the multimeter should show no voltage.
- For the magnetic Ignitor module, with the screw head in the locking ring not centered or aligned with the sensor in the module, the light should illuminate or the multimeter should show approximate battery voltage.
Rotate the crankshaft to position the flywheel or starter pulley with the desired timing mark aligned with the timing pointer or indicator on the engine. This is close to where the timing needs to be set.
With the Allen set screw loose in the locking ring, again...
- For the non-magnetic Dyna S or Ignitor modules and 3-wire inductive proximity sensor, with the magnet in the locking ring centered or aligned with the sensor in the module, the light should illuminate or the multimeter should show approximate battery voltage. It is at this point when spark occurs.
- For the magnetic Ignitor module, with the screw head in the locking ring centered or aligned with the sensor in the module, the light should be off or the multimeter should show no voltage. It is at this point when spark occurs.
Tighten the Allen set screw in the ring on the crankshaft. The ignition timing is now set close to where it needs to be.
Something cool to show off: To make a 12 volt in-dash indicator light or LED flash while cranking the engine and illuminate while the engine is running, for the Dyna S, Ignitor modules or 3-wire inductive proximity sensor connected to the HEI, Chrysler or Ford module, connect the light or LED to the negative (–) coil terminal and engine/chassis ground. The LED may shine bright, but the light will be dimly lit. The light or LED will not effect the performance of the ignition system whatsoever. It'll also let you know if the ignition system is working or not.

How to precisely set the ignition timing DYNAMICALLY (engine running) with an automotive inductive timing light for either sensor/module. (This is the most accurate way to set the timing.) NOTE: Timing can be checked, but not set while the engine is running! Do not allow sensor/module to make contact with locking set screw collar w/embedded rare earth magnet while engine is running! -

Start the engine, shine the timing light on the timing mark on the flywheel or starter pulley in relation with the pointer on the engine block to see where the timing needs to be set. NOTE: Do not use a battery charger alone to perform this test. Battery chargers constantly switch between high and low voltage at 60 cycles per second, and the module sees this as the ignition being switched on and off resulting in a continuous, constant array of sparks.
If the timing is not set correctly, shut off the engine and loosen the Allen set screw in the locking ring, slightly rotate crankshaft by hand one way or the other to advance or retard the timing, and position the locking ring with the magnet or screw head centered with the sensor in the module, and tighten the Allen set screw.
Start the engine again, shine the timing light on the timing mark on the flywheel or starter pulley in relation with the pointer on the engine block to see if the timing is set where it needs to be.
Repeat steps 1, 2 and 3 if necessary until the timing is set exactly where it needs to be, and securely tighten the Allen set screw.
No further bore.) OEM are required.

100% Maintenance-Free Custom Electronic Ignition Systems That Operate Off the Flywheel End of a Lawn & Garden Small Engine - Eliminates Points and Condenser

(Updated 7/10/17)

Get That Old Small Engine Running Again With 21st Century Technology Using 100% Digital Custom Electronic Ignition System, Even When New Replacement Parts Are Obsolete or Cost-Prohibited!

This is the era of modern wonders, where everything is transistorized, digitized and miniaturized. Yet even today, many garden tractor pullers still use breaker point ignitions on their garden pulling tractors. For other people, the frustration of attempting to keep a breaker point-fired tractor in peak running condition has been enough of a reason to join the electronic era. Breaker point systems do have some positives, though. Points are cheap and somewhat easy to install. And many people are comfortable with installing their own points. The bad side of using points is, besides the points contacts burning, pitting and wearing out, if or when the point gap gets too narrow, the ignition timing can get retarded, and when it gets too wide, the timing will become too advanced.

When the timing is retarded, the engine may be difficult to start, and when does start, it may not idle well, and it'll lack sufficient power. Also, with retarded timing, all of the fuel in the combustion chamber will not be burned. Part of the raw fuel will exit out of the exhaust, while the rest will remain in the chamber combustion and cling to the cylinder wall, causing the lubricating oil (from the crankcase) to become diluted. When this happens, "cylinder wash down" will result. Cylinder wash down is when the gas dilutes the thin coat of oil on the cylinder wall, and the piston rings will no longer be adequately lubricated, causing them to wear excessively, resulting in a smoky engine overtime. Cylinder wash down can also happen to a diesel engine when the fuel injectors are "turned up" or fuel delivery is increased so the engine will produce more power. (It will also blow a lot more black smoke out the exhaust.)

But when the ignition timing is too advanced, this will cause the engine to run too hot, which will likely cause the piston to swell, allowing it to make metal to metal contact against the cylinder wall, causing excessive wear. And the rings will lose their expansion against the cylinder wall as well. Eventually, due to the lose-fitting piston in the cylinder, the engine will create a rattling sound and start smoking out the exhaust, and it will ultimately need to be rebuilt.

If installed correctly, when the ignition is triggered off the flywheel, it stabilizes the ignition timing, so you won't ever have to worry about it. The engine will produce more power and you will have more confidence that the engine will last longer. So for the utmost precision ignition timing and maintenance-free convenience, flywheel-trigger electronic ignition is the way to go! It will allow the engine to idle smoothly and to its full potential with no hesitation or misfire.

Tired of changing or constantly adjusting the ignition points? Convert to the 100% digitized flywheel-trigger electronic ignition! For improved performance, easier starting, and less moving parts to leave your tractor dead on the track. Shock and moisture resistant, and all it takes is a few simple hand tools to install. In my opinion, getting rid of the points and condenser/capacitor has been the best advance ever in engine technology.

If a Kohler flywheel has no projection (hump) or OEM protruding bolt head for Breakerless Ignition, but does have a 3/4" wide area between the fins and ring gear (as shown in the pictures above È), or a billet steel flywheel, to use a magnetic pickup coil, 3-wire inductive proximity sensor, a small, short steel Phillips or button head socket head (Allen) screw and a minimum 1/4" length aluminum spacer secured with a split lock washer or high strength liquid threadlocker (Red Loctite, Permatex or equivalent) can be used as the signal detection for the flywheel-trigger electronic ignition. A steel dowel pin or knurled steel pin could be used instead of a screw or spiral pin, but because of exerted centrifugal force, the screw would be more secure due to its thread retention. FYI - When storing an opened, but capped container of liquid threadlocker or Super Glue, store it upright and not laying flat. The [capped] tip will not dry out and clog when stored upright.

The curvature or dome shaped heads of button- and Phillips-head screws makes them ideal for use on a trigger disc or flywheel. Spark occurs at the leading (high side) edge of the hump or screw, and not in the center of the hump or screw. When the magnetic pickup coil or cube-shaped proximity sensor is at the leading edge of the hump and when the S mark on the flywheel is aligned with the raised mark on the bearing plate, it is at this point the timing is at 20º BTDC. But if the flywheel has the 3/4" wide area, but no projection or hump", with the magnetic pickup coil or cube-shaped proximity sensor installed on the bearing plate and the 20º BTDC mark on the flywheel aligned with the raised mark on the bearing plate.

When using an inductive proximity sensor, being proximity sensors detect a farther distance (up to 3/16") than a magnetic pickup coil, install a 3/4" length steel screw with a 1/4" length aluminum spacer (to retain flywheel balance). This will extend the detectable target 1/4" above the surface of the flywheel to prevent an out of time spark occurrence by part of the flywheel itself. Or if using a non-magnetic pickup coil, 3-wire hall effect proximity sensor or a non-magnetic PerTronix Ignitor sensor/module, a small ring magnet fastened by a small screw can be used to create a rotating magnet detection target. The head of the screw will become magnetized.

An 8-32 UNC (coarse thread) and 10-32 UNF (fine thread) x 1/2" length screws with a split lock washer (and small magnet) only weighs about 1/10 of an ounce or 3 grams, so this will not make the flywheel significantly noticeably or dangerously out of balance. But if you're concerned about the flywheel being out of balance with the target screw/bolt, pin or screw w/ring magnet installed, the flywheel can be static balanced by weighing the flywheel and screw/bolt, pin or screw w/ring magnet separately on a precision scale, make a note of the exact weight of each item, and either install a stainless steel screw of the same exact weight as the trigger screw and magnet on the opposite side of the flywheel (180º apart), or drill a couple of shallow holes into the flywheel next to or beside the installed target screw/bolt, pin or screw w/ring magnet to put the flywheel back in balance. Make sure the flywheel is perfectly clean of dirt and debris, too. Actually, it's best to have the flywheel with the target screw/bolt, pin or screw w/ring magnet installed dynamically precision spin-balanced on a automotive balancing machine. Again, make sure the flywheel is perfectly clean of dirt and debris.

And for the ignition timing to be set at 20º BTDC, with the S mark on the flywheel and raised line on the bearing plate aligned, the screw will need to be located at 2-3/8" when using a magnetic pickup coil or proximity sensor. This setup can be adapted to a Kohler engine with the flywheel that has the starter/generator and gear starter alike. Or it can be applied to an engine with a steel flywheel for competition pulling. And the mounting holes in the angled bracket for the magnetic pickup coil can be elongated for precise adjustment/setting of the timing. If there's already a projection (hump) or OEM protruding bolt head on the flywheel, then there's no need to modify the flywheel for this conversion or upgrade. If they're not already present, new 10-24 UNC (coarse thread) threads will need to be drilled and tapped in the two raised bosses in the bearing plate to mount the bracket for the sensor's bracket. An original, ingenious, thoroughly researched and innovative concept invented by Brian Miller, because nobody else advertise this for use on a small engine.

Flywheel-Trigger Ignition Kit for Kohler engine models K141, K160/K161, K181, K241, K301, K321 and K341 with a small (8") flywheel and starter/generator. This simple and reliable ignition system kit produces a very strong spark, and the ignition timing will always be set at 20º BTDC, or wherever you set it. This system can be used on lawn & garden or stock competition pulling engines, with a cast iron or [8"] steel flywheel. Kit includes a non-magnetic PerTronix Ignitor sensor/module, aluminum channel spacer w/drilled holes and mounting screws, small rare earth/neodymium ring magnet, rubber cushioning/isolator washer and mounting screw (weighs 1/10 oz. / 6 grams). The sensor is activated by the South pole of the magnet, so do not remove the screw from the magnet! Tighten the screw just until the rubber washer begins to bulge. The Ignitor must be used with a minimum 3.0 ohm coil or it may burn up. NOTE: Neodymium and rare earth magnets are the strongest available. Five times stronger than ceramic (ferrite) magnets for stronger detection. So be extra careful when handling rare earth/neodymium magnets. They are very brittle and can break when snapped onto something or when the screw is overtightened. $75.00 per kit, plus shipping & handling.

Directions to install this kit..

Align or center the S timing mark on the flywheel with the timing sight hole in the bearing plate, and draw a line on the edge of and lengthways with the flywheel at the 10:30 position.
Draw another line 1" from the bearing plate crossways with the line on the flywheel. The magnet will install where the two lines intersect. This spot will allow the magnet to clear the flywheel shroud mounting boss on the bearing plate at the 4:30 position.
Drill and tap 6-32 UNF (fine thread) threads in the flywheel and install the magnet with the supplied rubber cushioning/isolator washer and screw where the two drawn lines intersect. IMPORTANT: Install the rubber cushioning/isolator washer between the magnet and flywheel, and secure the screw with high strength liquid threadlocker (Red Loctite, Permatex or equivalent). And install the ring magnet with the depression facing the flywheel. The ignition will not work otherwise. FYI - When storing an opened, but capped container of liquid threadlocker or Super Glue, store it upright and not laying flat. The [capped] tip will not dry out and clog when stored upright.
Thoroughly clean the bearing plate, and with the S mark on the flywheel aligned or centered with the timing sight hole in the bearing plate, center the Ignitor with the magnet, allow .010"-.060" clearance, mark on the bearing plate and drill and tap 6-32 UNC (coarse thread) threads in the bearing plate to mount the Ignitor and spacer. Be sure to apply dielectric, thermal or heat sink grease/paste between the Ignitor and aluminum spacer to help cool the module, and securely fasten the Ignitor/block to the bearing plate with the supplied 6-32 UNC (coarse thread) screws and split lock washers. Do not allow the module to make contact with the magnet/screw while engine is running!
Drill a 1/4" or 3/8" hole through the bearing plate behind the Ignitor and route the wires from the Ignitor to the ignition coil. Wallow out the drilled hole or use a rubber grommet to prevent the insulation on the wires from rubbing and possibly being shorted, or apply clear RTV silicone adhesive sealant in the hole to hold the wires rigid.
Disconnect and do away with the wires to the points and condenser. Connect the BLACK wire on the Ignitor to the coil negative (–) terminal, and connect the RED wire on the Ignitor to the coil positive (+) terminal and to the ignition switch (battery positive (+) post). IMPORTANT: If the wires are connected in reverse, the Ignitor will burn up instantly when power is supplied!
Spark plug should be gapped at .035". Turn on the ignition switch, rotate the flywheel back and forth by hand or crank the engine with the starter/generator, and observe for a strong, blue spark at the spark plug's tip.

Custom Electronic Ignition Kits (Below) for Converting from Breakerless Ignition or Points/Condenser Ignition to flywheel-trigger Ignition for Kohler engine models K241, K301 or K321. (K341 and K361 engines originally did not come with Breakerless Ignition.) Do away with the old fashioned points and condenser ignition, or defective and cost-prohibitive Breakerless Ignition components, and convert your engine to the reliability, dependability and durability of flywheel-trigger ignition. NOTE: These flywheel-trigger ignition parts do not install on the PTO end of the crankshaft and engine block. Instead, they install next to the flywheel on the OEM Kohler bearing plate. To replace the points/condenser with flywheel-trigger, engine can have the small bearing plate with two drilled holes to install the triggering device and 8" flywheel with a small screw/bolt (for magnetic pickup coil or 3-wire inductive proximity sensor) or a small ring magnet (for the non-magnetic PerTronix Ignitor sensor/module installed on edge of flywheel in a specific place for timing purposes and to trigger the ignition, OR engine can have the large bearing plate with two mounting bosses to install the triggering device and 9" flywheel with 3/4" wide area with the OEM projection (hump), OEM protruding bolt head or install a small screw/bolt (for magnetic pickup coil), or small ring magnet (for non-magnetic PerTronix Ignitor sensor/module on edge of flywheel in a specific place for timing purposes and to trigger the ignition. Must use a universal battery ignition key switch, or an OFF/ON toggle- or key-switch (for ignition) and push-button starter switches for either ignition system listed below Ê. NOTE: No need to remove the brass cup plug from points pushrod hole. Ignition timing will be set at 20º BTDC with kit, and reuse same type of spark plug, but set gap at .035". An original, ingenious, thoroughly researched and innovative concept invented by Brian Miller, because nobody else advertise this for use on a small engine. Please accept no other advertised copycat products of this kind. IMPORTANT: The wire that comes from the stator under the flywheel for Kohler Trigger Module or Tecumseh Solid State Ignition Module generates about 250 volts (serious) while the engine is running at full governored speed. Do not touch this wire (terminal) with one bare hand and the engine itself with your other hand while the engine is running! It is not needed any of my Custom flywheel-trigger electronic ignition systems. So snip off this wire or tape up the terminal to prevent a short circuit or electrocution.

Custom-Made Self-Contained Electronic Ignition Systems Designed for Tecumseh engine models VH80, VH100, HH80, HH100, HH120, OH120, OH140, OH150, OH160 and OH180. Concept and design by Brian Miller.

A-1 Miller's Self-Contained Custom-Made Electronic Ignition Systems Designed for Tecumseh engine models VH80, VH100, HH80, HH100, HH120, OH120, OH140, OH150, OH160 and OH180. Our 12 Volt Flywheel-Trigger High Performance Electronic Ignition Conversion Ignition Systems Integrated with a Durable High Energy Ignition Coil Are Built with the Latest State-of-the-Art Engineering. Works equally for lawn and garden use as well as for competition pulling. These systems works much better than a CDI ignition designed for a Chinese motorbike. Ignition components and ignition coil will be pre-wired and fastened onto a durable 3/16" thick 6061-T6 aluminum plate that mounts in place of the OEM Tecumseh solid state ignition module. No need for additional wiring and a separately-mounted ignition coil to clutter up the engine compartment. Grind down protruding block of metal on cylinder for clearance of GM 4-pin HEI module. Use lock washers on the screws and tighten screws securely when fastening the plate to the engine block to prevent loosening. Each ignition system have been thoroughly tested, produces a very strong spark, are very reliable and requires 12 volts of power with one wire hook up. Drive the long steel firing pin (0º TDC) flush with the surface of the flywheel or remove it entirely. Set clearance/air gap between short steel firing pin and sensor at 1/8". And being this ignition system is triggered off the short pin in the flywheel (20º BTDC), the timing will be in the advanced setting at all times with no retard and no automatic compression release. Therefore, two switches will be required to start the engine. One being a push button switch to crank the engine, and the other an OFF/ON toggle or key switch to power the ignition. To start the engine, first crank it over, and while it's cranking, choke the carburetor (or use my remote fuel primer system, which works much better and is easier to use), and then "put the spark to the engine" by flipping on the toggle switch or turning on the key switch. The engine should start easily and quickly every time. This works because the centrifugal force of the heavy spinning flywheel prevents the engine from "kicking back" when power is first supplied to the ignition. If the engine has an automatic compression release, this will not need to be done. Also, do not connect the wire coming from the stator (behind the flywheel) to any of my custom-made electronic ignition systems or they will burn up. IMPORTANT: The coil and/or module may burn up if the ignition switch is left on for more than 5 minutes with the engine not running. So to prevent this from happening (accidentally), for 100% assurance, install a high amperage main disconnect/cutoff switch that kills the power to everything on the equipment, or install a bright (LED) indicator light that illuminates when the ignition switch is on, or install an illuminated (lighted) OFF/ON toggle switch for the ignition. Each ignition system replaces Tecumseh CDI system part #'s 610-748, 610-855, 610-906 and John Deere part # AM31741. Made in USA. Comes with a one year warranty from date of purchase. Concept and design invented by Brian Miller. "Perfection takes time. If it's worth having, it's worth waiting for." NOTE: These ignition systems will not work on a Tecumseh engine with a flywheel that has an embedded external magnet to fire the magneto ignition with points and condenser. With this type of flywheel, when the OEM magneto ignition coil fails, which may be no longer available, the engine can be converted to a reliable battery-powered ignition system instead. A battery-ignition key switch will also need to be used. Top of page.

Self-Contained Custom-Made Electronic Ignition Conversion System for Tecumseh engine models VH80, VH100, HH80, HH100, HH120, OH120, OH140, OH150, OH160 and OH180. Includes a cube-shaped 3-wire inductive proximity sensor, high quality ordinary/stock GM 4-pin HEI electronic ignition control module, and epoxy-encapsulated armature-frame ignition coil. Set air gap/clearance between short pin and sensor at 1/8", and set spark plug gap at .035". $150.00 each, plus shipping & handling.

(Posted 11/3/17) Custom Flywheel-Trigger Electronic Ignition Conversion Kits for Kohler opposed twin cylinder engine models KT17 Series II and KT19 Series II. This ignition system works flawlessly! Replaces points and condenser. Ignition points can be removed and the points pushrod hole can be permanently plugged with a short 1/4" bolt, Allen set screw or clear RTV silicone adhesive sealant. Each ignition system listed below works excellent with the OEM Kohler 4.0 ohm twin cylinder ignition coil to produce a strong, reliable spark. NOTE: Two bosses on the #1 cylinder (right side when facing flywheel) must be drilled and tapped to accept 1/4-20 UNC x 1" mounting bolts (drill only 3/4" deep; do not drill all the way through the cylinder wall!), and a specific location on the edge of the flywheel must be drilled and tapped to accept the 6-32 UNC (coarse thread) detectable target screw or magnet w/cushioning/isolator rubber washer and screw. The sensor is activated by the South pole of the magnet, so do not remove the screw from the magnet! Install screw in flywheel with high strength liquid threadlocker (Red Loctite, Permatex or equivalent), and tighten screw w/magnet just when the rubber washer begin to bulge. (FYI - When storing an opened, but capped container of liquid threadlocker or Super Glue, store it upright and not laying flat. The [capped] tip will not dry out and clog when stored upright.) An original, ingenious and innovative concept design invention by Brian Miller. These ignition systems will not work on the first design KT17 and KT19 engines because there are no bosses on the cylinder(s) to drill for bolt holes to mount the ignition bracket. However, the cylinder(s) off a KT17 Series II, MV16, M18 and MV18 will work on a first design KT17 engine, and the cylinder(s) off a KT19 Series II, M20 and MV20 engine will work on a first design KT19 engine. The only difference between the KT17, KT17 Series II, MV16, M18 and MV18 cylinders, and KT19, KT19 Series II, M20 and MV20 cylinders is the length of the valves. I realize this would be a lot of work just to use electronic ignition on a first design KT17 or KT19 engine, but this is the best way of making it happen.

Magnetic pickup coils and round-shaped proximity sensors are very sensitive to mechanical damage (and electrical damage if connected wrong). For magnetic pickup coils, set the air gap/clearance from the detectable target (screw, pin or small raised area on the rotating disc) at .010"-.060" with a brass, plastic, business card, poster board, stainless steel (anything non-magnetic) feeler gauge. And being 3-wire inductive proximity sensors have a farther detection range, set the air gap/clearance at .010"-.188". If the gap is wider than specified with either sensor, the engine could misfire at higher RPM. To prevent the possibility of an out of time spark, the detectable target needs to be a minimum of 3/16" higher than or above the circumference surface of a steel or cast iron rotating disc or flywheel. Direct metal contact with either sensor could damage them. When in doubt if a sensor is mechanically damaged, look at the end of it with the strong magnifying glass to see any damage. If it is damaged, it needs to be replaced. A magnetic pickup coil can be tested with a digital multimeter set on 200m DC, with the negative lead of the meter on the white wire of the pickup coil and positive lead on the black wire, then pass a small steel screw or bolt over the end of the magnetic pickup coil. If the meter shows a reading, the pickup coil is in good condition.

Being 3-wire inductive proximity sensors have a farther detection distance, set the air gap/clearance at .010" - .188". Direct metal contact with either sensor will damage them. And if the gap is wider than specified, the engine could misfire at higher RPM. To prevent the possibility of an out of time spark, the detectable target needs to be a minimum of 3/16" higher than or above the circumference surface of a steel or cast iron rotating disc or flywheel.

(The PerTronix Ignitor I and II, Dynatek Dyna S modules and hall effect proximity sensors are activated by the South end of the magnet. They won't do anything from the North end.) And neodymium and rare earth magnets are the strongest available. Five times stronger than ceramic (ferrite) magnets for stronger detection. Be extra careful when handling rare earth/neodymium magnets. They are very brittle and can break when snapped onto something or when the screw is tightened too much. Install the rubber cushioning/isolator washer between the magnet and flywheel, and secure the screw with high strength liquid threadlocker (Red Loctite, Permatex or equivalent). Tighten the screw/magnet just until the rubber washer begins to bulge. FYI - When storing an opened container of liquid threadlocker or Super Glue, store it upright and not laying flat. The [capped] tip will not dry out and clog when stored upright.

Now the ordinary/stock 4-pin GM HEI electronic ignition control module lives up to its name, High Energy Ignition! When used on a small engine, in order for an ordinary/stock 4-pin HEI module allow the engine accelerate to its full potential, it must be used with the cube-shaped 3-wire inductive proximity sensor, and can be used with virtually any ignition coil, regardless of the ohms resistance or voltage output. A metal core conductor spark plug wire and Copper Core/Non-Resistor spark plug should be used. Set spark plug gap at .035". Sensor is also capable of powering an HEI crank-trigger ignition and a digital tachometer at the same time. This concept revolutionizes the use of this small, compact and versatile module! This is a thoroughly tested, researched and proven reliable ignition system invented by Brian Miller for ordinary lawn and garden engines and competition pulling engines. And when mounting the GM 4-pin HEI module, always fasten it with dielectric, thermal or heat sink grease/paste on a clean, flat aluminum plate with plenty of fresh air circulation to dissipate the heat while in operation. Click here for wiring diagrams. IMPORTANT: The wire that comes from the stator under the flywheel for Kohler Trigger Module or Tecumseh Solid State Electronic Ignition Module generates about 250 volts (serious) while the engine is running at full governored speed. Do not touch this wire (terminal) with one bare hand and the engine itself with your other hand while the engine is running! It is not needed for any of my crank-trigger ignition systems. So snip off this wire or tape up the terminal to prevent a short circuit or electrocution. [Return to Previous Section, Paragraph or Website]

High Torque Gear Starter Motors for Kohler engine models K141, K161 and K181 single cylinder cast iron block Kohler engine. 12 volt, 16 tooth gear. All starter motors are high torque nowadays. They have 20% more wire windings than the early OEM Kohler starter, giving it 20% more cranking power. Draws less amps; a smaller battery can be used. Cranks engine about twice as fast and draws less amps than an ordinary starter. But with a broken compression release, a high torque starter may not be able to crank the engine. It'll be best to adjust the valve clearances, repair the compression release mechanism or replace the cam with a working compression release. FYI - The aftermarket starter motors I sell are the same as OEM Kohler starters. Kohler just place a big markup on theirs because it comes in a Kohler brand box and the starter has the Kohler name stamped on it. Kohler part # 41 098 08-S. New high quality aftermarket starter. Comes with manufacturer's 100% unconditional one year warranty. Replaces Kohler part # 41 098 08-S. $90.00 each, plus shipping & handling. New OEM Kohler starter. Comes with a 90 day warranty against defects in materials or workmanship. OEM Kohler part # 41 098 08-S. $190.00 each, plus shipping & handling. Most quality-made starter motors are designed to last the life of the engine. Therefore, if a good starter burns up prematurely, then this means that it has cranked the engine for too long at one time. All starters are actually 6 volt motors operating on 12 volts. This is what gives them so much torque to crank the engine so fast and with ease. So if a starter motor is spun too long (longer than 2 minutes), the excess voltage will burn up the wire windings in the starter. The longer it's spun, the hotter it will get, which causes the windings to get very hot, which causes the insulating/separating varnish coating on the windings to melt. When the coating melts, the windings make contact with each other and become shorted out, and you have a burned up starter on your hands. That's why most owner's and repair manuals say to never crank an engine longer than 2 minutes at a time without allowing adequate time for the starter to cool before cranking it again. (If an engine won't start within 2 minutes of cranking, then it obviously needs a major tune-up or repair!)
10 and 13 Tooth Upper Mount (mounting bolts are below starter) High Torque Gear Starter Motors for Kohler K-series engine models K241, K301, K321, K341 and K361. 12 volt. All new starter motors are high torque nowadays. They have 20% more wire windings than the early OEM Kohler starter, giving it 20% more cranking power. Cranks engine about twice as fast and draws less amps than an ordinary starter. Therefore, a smaller battery can be used. In addition to the extra windings, the 10 tooth starter gear gives this starter extra torque so it'll crank the engine with less effort. The 10 tooth starter provides 13% more cranking torque than the 13 tooth starter, and the 13 tooth starter cranks the engine over 30% faster than the 10 tooth starter. The 13 tooth starter is best to be used with working compression release. But with a broken compression release, a high torque starter may not be able to crank the engine. It'll be best to adjust the valve clearances, repair the compression release mechanism or replace the cam with a working compression release. FYI - The 10 tooth starter cannot be used in place of the 13 tooth starter, but the 13 tooth starter can be used in place of the 10 tooth starter by shimming/spacing the starter away from the engine block with an ordinary flat washer on each mounting bolt. And the aftermarket starter motors I sell are the same as OEM Kohler starters.

(If an engine won't start within 2 minutes of cranking, then it obviously needs a major tune-up or repair!)
High Torque Lower Mount (mounting bolts are above starter) Gear Starter Motors for Kohler engine models K241, K301, K321, K341 and K361 engines. 12 volt. All new starter motors are high torque nowadays. They have 20% more wire windings than the early OEM Kohler starter, giving it 20% more cranking power. Draws less amps; a smaller battery can be used. Cranks engine about twice as fast and draws less amps than an ordinary starter. In addition to the extra windings, the 10 tooth starter gear gives this starter extra torque so it'll crank the engine with less effort. But with a broken compression release, a high torque starter may not be able to crank the engine. It'll be best to adjust the valve clearances, repair the compression release mechanism or replace the cam with a working compression release. FYI - The aftermarket starter motors I sell are the same as OEM Kohler starters. Kohler just place a big markup on theirs because it comes in a box with the Kohler name on it and the starter has the Kohler name stamped on it. New high quality aftermarket starter.

Comes with a 90 day warranty against defects in materials or workmanship. OEM Kohler part # 45 098 10-S. $216.00 each, plus shipping & handling. Most quality-made starter motors are designed to last the life of the engine. Therefore, if a good starter burns up prematurely, then this means that it has cranked the engine for too long at one time. All starters are actually 6 volt motors operating on 12 volts. This is what gives them so much torque to crank the engine so fast and with ease. So if a starter motor is spun too long (longer than 2 minutes), the excess voltage will burn up the wire windings in the starter. The longer it's spun, the hotter it will get, which causes the windings to get very hot, which causes the insulating/separating varnish coating on the windings to melt. When the coating melts, the windings make contact with each other and become shorted out, and you have a burned up starter on your hands.

Universal Analog 10 Amp and 20 Amp Ammeter / Amp Gauge Kits. Gauges registers up to 10 or 20 amps of charge, depending on total output amperage of stator or alternator. Install these gauges to know exactly what the charging system on your engine is doing. Having an ammeter/amp gauge installed is very important in monitoring the charging system to prevent premature failure of electrical components. By the time you smell something burning or see smoke, it may be too late. If the charging system continues to charge on the plus (+) side with no gradual moving back of the needle to zero on the gauge (if installed) while the engine is running at full governored speed, this will send too much voltage to the battery, which could eventually burn up the cells in the battery, or burn up the primary windings in the ignition coil. Overcharging of the electrical system could also burn up the electronic ignition control module/unit (crank-trigger and flywheel-trigger), burn out light bulbs, electric PTO clutch or any other electrical accessories. As battery becomes fully charged, needle slowly moves from positive side (+) to zero (0). Needle will stay on negative side (–) if no charge goes to the battery. Or gauge will not show any charge at all if charging system is not working. Easy 2-wire connections. Connect the positive (+) terminal on back of gauge to the battery positive (+) post, and connect the negative (–) terminal on back of gauge to the wire going to the ignition switch that provides power to the ignition and all accessories. If the wires/connections are reversed, and if the charging system is in good working condition, the gauge will show discharge (–) instead of charge (+). Use minimum 12 gauge stranded wire. Non-lighted gauges. Each requires 2" diameter mounting hole and comes with mounting clamp and nuts.

New 12 volt, 15 Amp Analog Voltage Regulator for Starter/Generators. If the charging system continues to charge with no gradual moving back of the needle to zero on an analog ammeter/amp gauge (if installed) while the engine is running, this will put too much voltage through the coil, eventually burning out the primary windings. Overcharging of the charging system could also burn up the electronic ignition control module (crank trigger), burn up the battery, burn out light bulbs, electric PTO clutch and any other electrical accessories. With the terminals facing you, they read: L (Lights) \| Bat (Battery) \| F (Field), with A (Armature) on the bottom. L connects to the Lights (if equipped); Bat connects to the ignition switch, which connects to the positive (+) post on the battery; F connects to the Field terminal on the starter/generator; and Armature connects to the Armature terminal on the starter/generator. The frame of the regulator must be securely grounded to the tractor or equipment through the mounting bolts. NOTE: Cannot be substituted for use with the alternator/stator charging system.

Two Wire Semiconductor Rectifier Diodes. Either can be used as a rectifier in a small engine 3 amp non-regulated stator alternator charging system to convert alternating current (AC) to direct current (DC) to recharge the battery and/or power low-amperage electrical accessories. Not needed to power lights or an electric PTO clutch. Or can be used to excite or energize the field windings in a belt-driven automotive alternator or direct-drive 120/240 AC volt portable generator when powered by a small engine so alternator/generator will produce electricity as soon as the engine starts. High quality aftermarket. .50¢ each, plus shipping & handling. Briggs & Stratton part # 393814. $6.00 each, plus shipping & handling. Diode kit. OEM Kohler part # 25 755 31-S. $12.52 each, plus shipping & handling. FYI - Briggs & Stratton engines have either one or two OEM alternator stators and they are joined together in two half circles under the flywheel. Some engines only come with one half stator. Each half produce 3 amps of power & 14 volts @ 3,600 RPM. If an engine comes with two stators joined together, one half produces AC, which is used to power the lights and electric PTO clutch. And the other half also produce AC, but is connected to a minimum 3 amp/14 volt diode, which is used to only recharge the battery. Under normal yard use, 3 amps is not enough to overcharge and burn up the battery. If both stator halves are wired together from the factory (as they are on certain engines), they will produce 6 amps of AC power and a 6 amp solid state electronic voltage rectifier/regulator is used to power the lights, electric PTO clutch and recharge the battery.

NOTE: The solid state electronic voltage rectifier/regulators shown works the same. The orientation of the terminals are for various applications. Also, the small size voltage rectifier/regulator is to be mounted in the opening of the flywheel shroud so air from the flywheel will keep the regulator unit cool while in operation. If it's mounted elsewhere with no fresh air blowing over it, it could burn up prematurely. And these cannot be substituted for use with the starter/generator charging system.

NOTE: All parts listed here are NEW, unless otherwise stated. I do not sell cheap junk! As a matter of fact, many of the OEM Kohler K-series and Magnum engine parts are still made in the U.S. The Kohler Courage engines and parts are made in China. As a matter fact, Kohler owns two factories in China that make the parts. And most aftermarket parts listed in this website are also made by Kohler to Kohler's strict specifications. Kohler just place the part(s) in a generic box and sell them for less money. So when purchasing a genuine OEM Kohler part that comes in a box with the Kohler name on it, you're really just paying more money for the name on the box. The OEM [US] manufacturers are phasing out many parts for flathead engines due to EPA smog emissions. But some parts may still be available in aftermarket.

NOTE: I sell individual engine parts only. Because with "complete" engine rebuild kits that others offer, they always sell you extra parts your engine don't need, and/or leave out parts your engine do need. Completely disassemble your engine to determine which parts your engine needs and if the cylinder in your block and crank journal needs machine work performed, then email me a list of parts. Include the engine's model and specification numbers, too.

NOTE: High-quality ring sets, pistons and piston/rings assemblies are also available for other makes and models of small gas engines. And the piston assemblies that's offered here will work with a stock connecting rod and crankshaft without the need for rebalancing. And always match a billet connecting rod of a certain length to an aftermarket piston (Arias, JE, etc.) that has the correct compression height. These two parts must be matched for the piston to come flush with the top of the engine block, or have a few thousands of an inch pop-out. If using a Kohler connecting rod, the compression height may not be correct with an aftermarket piston (Arias, JE, etc.) that has the wrong wrist pin offset. The same is true with a Kohler piston and a billet connecting rod of a the wrong length. You can find piston ring compressors on eBay.

NOTE: Complete engine rebuild kits are available, but a kit will cost more than if the parts were purchased separately. So please contact me with a list of parts you need, and I'll get back to you with a total amount including shipping & handling. And if you need a part or parts that's not listed here or for other make and model of engines. Please contact me and I'll see if I can get it at a reasonable price. Please contact me if you're interested in any of the above È parts or items.

New and Used OEM and Aftermarket Replacement Connecting Rods - | Please contact me if you're interested in any of these parts or services.

Upon installation of a connecting rod in a Kohler engine, the oil hole in the cap faces toward the camshaft! There's "match marks" on both the rod and rod cap. They MUST be aligned or "matched up" so the big end of the rod forms a perfect circle around the crank journal when installed. Otherwise, if the cap is installed backwards, the "perfect circle" will be oblong or "egg-shaped," which will bind on the crank journal. And DO NOT over-tighten the rod bolts or nuts! If the threads strip out in a rod, then perhaps a longer grade 8 fine thread bolt can be installed in reverse to serve as a stud (the rod will need to be machined for head bolt clearance) and use a grade 8 nut. If this cannot be done, then the rod is scrap metal.

Connecting rods for Kohler engine models K90/K91. Not available in aftermarket. L NOTE: Crank journal must be reground .010" undersize to match this rod. The alternative to using an undersize rod is if a STD size or .010" undersize rod is in good condition, if the matching-size crank journal isn't deeply scored and/or badly burnt, it can be reground until it's perfectly round again and then if the original rod also isn't deeply scored and/or badly burnt, it can be resized to fit to odd-size undersize journal with the factory recommended .0025" oil clearance. NOTE - The maximum a connecting rod can be resized to is .005" undersize. If it's resized more than .005", being the big hole in the rod will be made excessively oblong or egg-shaped, which will allow it to less bearing surface contact around the crank journal after being resized, due to the centrifugal force at 3,600 RPM, the big end of the rod could become elongated (metal stretch) and might eventually knock and possibly break. IMPORTANT: To prevent scoring of the rod when the engine is started for the first time, apply clean motor oil, gear oil or lubricating grease or on crank journal before installing rod. This will better protect the parts until crankcase oil reaches them. IMPORTANT: Click here for proper break-in (wear-in) oils and procedure for rebuilt engines.

These are plain aluminum bearing surface rods, but I can bore rod and install STD size, .010", .020" or .030" undersize replaceable bearing inserts if you wish. 5.3" length. NOTE: All 16hp rods, K-series or Magnum, have a narrow wrist pin hole. Also, these rods can be bored for installation of STD size, .010", .020",or .030" undersize bearing inserts, and crank journal must be reground to match diameter of undersize bearing inserts. Crank journal must be reground .010" undersize to match this rod. The alternative to using an undersize rod is if a STD size or .010" undersize rod is in good condition, if the matching-size crank journal isn't deeply scored and/or badly burnt, it can be reground until it's perfectly round again and then if the original rod also isn't deeply scored and/or badly burnt, it can be resized to fit to odd-size undersize journal with the factory recommended .0025" oil clearance. Bearing inserts cannot be used. NOTE - The maximum a connecting rod can be resized to is .005" undersize. If it's resized more than .005", being the big hole in the rod will be made excessively oblong or egg-shaped, which will allow it to less bearing surface contact around the crank journal after being resized, due to the centrifugal force at 3,600 RPM, the big end of the rod could become elongated (metal stretch) and might eventually knock and possibly break. IMPORTANT: To prevent scoring of the rod when the engine is ran for the first time, apply clean motor oil, gear oil or lubricating grease on crank journal before installing rod. This will better protect the parts until crankcase oil reaches them. IMPORTANT: Click here for proper break-in (wear-in) oils and procedure for rebuilt engines.

(Updated 7/18/18) Connecting rods for Kohler engine models K482, K532, K582 and K660/K662 are Discontinued from Kohler. Used and New Old Stock rods can be purchased off of eBay when available. And with the crankshaft rod journals reground to .010", .020" or .030" undersize, the K482, K532 or K582 connecting rods can be bored for installation of bearing inserts. Instead of boring a new or used connecting rod that has a smooth, undamaged bearing surface for installation of bearing inserts, a rod with a burnt or scored bearing surface can be bored out to make room for bearing inserts. Bearing inserts that's made for certain British MG Midget cars will fit the K482, K532 and K582 rods perfectly when the rods are bored to accept these (STD size, .010", .020" or .030" undersize) bearing inserts. Bearing inserts for Kohler engine models K482, K532 and K582: SEALED POWER 465905RA or MAHLE/CLEVITE CB488P. Interchange part numbers: 42965CP, 4B2201STD, 4-2965CP, CR417AM. Virtually any auto parts store should have or can get these bearings. Minimum STD size rod journal diameter: 1.625"; Minimum connecting rod bore size: 1.7705" / 45mm; Bearing width: 0.8800"; Maximum oil clearance: 0.0033". The alternative to using inserted rods - if a STD size or .010" undersize rod is in good condition, the matching crank journal can be reground until it's perfectly round again, then if the original rod isn't deeply scored and/or badly burnt, it can be resized (in a connecting rod honing machine) to fit or match the odd-size undersize journal with the factory recommended .0025" oil clearance. Bearing inserts cannot be used in this procedure. However, the maximum a connecting rod can be resized to is .005" undersize. If it's resized more than .005", being the big hole in the rod will be made excessively oblong or egg-shaped, which will allow it to less bearing surface contact around the crank journal after being resized, due to the centrifugal force at 3,600 RPM, the big end of the rod could become elongated (metal stretch) and could eventually knock and possibly break.

8 Ball Main Crankshaft Radial Bearings for Kohler K-series and Magnum cast iron block engine models K241/M10, K301/M12, K321/M14, K341/M16 and K361. Heat treated. These are specifically designed to provide maximum performance through precise ball implement selection. Aftermarket bearing packed with fresh grease from the factory. Suitable for general lawn and garden or high performance use, at high RPM or at wide open throttle, bigger balls rotate freer, run cooler which create less rolling resistance and friction than a bearing with smaller balls. Dimensions: 1.57" (40mm) i.d. x 3.54" o.d. (90mm) x .90" (23mm) width. See note below Ê. NOTE: If yours have more than .005" of play due to wear, or it feels rough or "rubbles" when rotated by hand with motor oil applied, then it needs to be replaced. FYI - All ball bearings have always been made to the metric dimensions. Where applicable, the US and import manufacturers try to make them close to the inch dimensions as possible.

NOTE: With the main bearings removed from an engine, and if all the oil is cleaned from the bearings, allowed to thoroughly dry, and when the bearings are spun by hand, and if the bearings isn't worn much or at all, they might feel "rough" and make a rattling sound. This rattling sound isn't necessarily because the bearing is worn. The noise is caused by the balls running dry on the races because there's no oil to separate them. They're simply making metal to metal contact. Try applying a small amount of motor oil to the balls/races then spin them. They should now be a lot quieter. The same thing will happen with new radial ball bearings. By the way - Most main bearings in a Kohler engine will wear extremely little, if any at all, and usually don't require replacing. Although some main bearings will wear (which is obvious), and need to be replaced. And excessively worn main bearings will make a rumbling noise and the engine will have a more than-usual-vibration.

Install STD size, .010", .020" or .030" undersize Replaceable Bearing Inserts in Connecting Rods for Kohler engine models K241/M10, K301/M12, K321/M14, K341/M16, K361 M20 and MV20. Rods for the before mentioned engines can be bored and notched to accept bearing inserts. Even severely burnt, scored, or rods with a mismatched cap can be bored for installation of bearing inserts. Only USA-made Clevite 77, Federal Mogul or Sealed Power bearing inserts will be installed. No low quality Chinese-made bearing inserts ever installed. All A-1 Miller machined connecting rods include ground-out notches to prevent bearing rotation in rod and drilled oil hole for proper lubrication. Please indicate diameter of crank journal for size of bearing inserts. (STD size, .010", .020", .030" or .060" undersizes.) Also, rods can be center-bored for top of piston to come flush with deck, or bored .020"± offset for a .020"± piston pop-out at no extra charge.

Purchase one of our rods, bore and notch rod and install our bearing inserts: Price of rod $? + $20.00 for bearing inserts + $25.00 labor to bore rod = $? total, plus return shipping & handling.

NOTE: If a crank journal is worn beyond specs or badly scored/burnt,it will need to be reground to the next undersize to match the appropriate size bearing inserts. And if you want me to bore a rod for you, please let me know if you want the bearing insert centered in the bore of the rod (5.300" rod length; piston flush with top of block), offset .020" (5.320" rod length; safe to use with a milled OEM Kohler stock head and stock head gasket) or offset .060" (5.360" rod length; use with a non-milled OEM Kohler head and stock head gasket) to pop the piston out of the cylinder (see below Ê) to raise the compression and help improve airflow within the combustion chamber for more power and torque. The bearing inserts I install in Kohler 10-16hp flatheads and 18hp OHV K361 connecting rods can be used for general lawn and garden use, stock or high RPM competition pulling engines. The rod will need to be bored exactly 1.625" for correct bearing to journal oil clearance.

NOTE: Being virtually all Kohler K241/M10 pistons come within .020"± from the top of the block, which lowers the compression ratio. (The factory made them this way for reasons unknown.) I prefer to bore the K241 10hp rods .020" offset so the piston will come flush with the top of the block. This will allow the engine to produce a little more power. It won't effect the longevity of the engine or cause any problems whatsoever. But sometimes with the .020" offset, the piston will pop out of the cylinder a few thousandths of an inch, which will still hurt nothing. And the bore can be offset .040" for a .020"± piston pop-out.

FYI - Before I machine a rod for installation of bearing inserts, I use a metal "plug" alignment tool that I fabricated to precisely align the big hole of the connecting rod with the centerline of the spindle in my milling machine. Then while the plug is in the rod, I firmly clamp the rod to the milling machine table and after leaving the big hole centered or moving the table so many thousandths of an inch offset for piston pop-out, I lock the table so it won't move in any direction while boring the rod. But for reasons unknown, sometimes the cutting tool will bore the hole in the rod slightly off-center toward one of the bolts or studs. When this happens, I simply grind a small notch on the outside of each bearing shell so they'll clear the rod bolt. I've talked to other machinists who bore Kohler rods also about this and they tell me sometimes the same thing happens to their rods. But as long as the outside of the bearing shells are notched for clearance of the bolt or stud, the off-center of the bearing inserts poses no problems whatsoever.

And bearing inserts for the 10-16hp Kohler engines can be installed in Kohler engine models K482, K532 and K582 STD size connecting rods, but the crank journals would need to be reground exactly to 1.500" to match the inside diameter of the bearing inserts when installed in the rods. And for your information, STD size crank journals for the K482, K532 and K582 engines measures 1.6245".

Narrow wrist pin width on 12hp or 14hp (old style) connecting rod for use with K-series 16hp cast piston or "new style" Mahle (Magnum) forged pistons. $20.00 labor, plus return shipping & handling.

Cylinder Containment Strap Kit for Kohler 10-16hp K-series and Magnum Engines. Professionally made. This setup is easy to remove and reinstall when it comes time to freshen the engine.

Exhaust. OEM Kohler part # 220009-S. $45.05 each, plus shipping & handling.

NOTE: Before lapping in the valves, it'll be best to have the valve seats reground or cut so they'll be in correct alignment with the centerline of the valve guides. Otherwise, the valves may not make a full 360º contact with the seats, and the engine will lose compression, be hard to start, lose power and possibly make a popping sound through the carburetor or out the exhaust. And be sure to set the clearances correctly, too. And if the end of the valve stem is accidentally ground too short, it can be made long again by building up welding with a MIG or TIG welder, then ground to the correct valve clearance.

Duplicate of the Popular and Sought After OEM Kohler K361 18hp OHV (Over Head Valve) Camshaft -

When used in Kohler flathead engine models K241/M10, K301/M12, K321/M14 or K341/M16, this particular cam profile design provides more torque (lugging power) and improved engine performance from 3,400 to 3,800 RPM. The lobes on this cam are professionally reground to have the factory stock lift (.324"), but a slightly less duration than the 4,000± RPM reground torque cam below Ê, which makes it perform best at a lower RPM range. This cam builds up the compression about 4% more at 3,600 RPM than the stock flathead engine cams. It's ideal for general lawn and garden work, snow removal and/or in a limited RPM stock competition pulling engine. Due to the low RPM range, it can be used with factory stock valve springs. No need for performance springs. Set the valve clearances at .010" for the intake and .014" for the exhaust. This cam profile is Discontinued from Kohler. Replaces OEM Kohler part # 45 010 05-S.

Please send to: A-1 Miller's Performance Enterprises, 1501 W. Old Plank Rd., Columbia, MO (Missouri) 65203-9136 USA.

FYI: When the cam lobes are reground, metal is removed from the base circle which reduce the diameter of the base circle in order retain maximum lift at the highest point on the lobe. The ramps on the lobes are also "rounded" to give the cam more duration. The cam grinding machine's grinding stones are about 1" wide, and after the cam grinding process, I have to manually grind metal away from the sides of the base circles so the edge of the lifters won't "ride up" on the ungrounded areas and hold the valves slightly open when they're supposed to be fully closed. I have to do this to every reground cam I have in stock. Some cam grinders apply a phosphate conversion coating (which resembles flat or matte black paint) to the entire camshaft, especially the lobes. This coating is to prevent galling (wear) during the break-in (wear-in) period and it also covers the secondary grinding areas on each side of the base circles of the lobes so they can't be readily easily seen or noticed. Motor oil with high zinc phosphate content will also protect the cam lobes and other internal moving engine parts from wear during break-in (wear-in). Otherwise, if everything else is set up correctly with your engine, this cam should work fine. There's no need to be concerned when you receive the cam and see the metal ground away. Also, some of the cams I have, the points lobe is slightly worn. (It's hard to find a good used, 100% unworn cam nowadays.) I include a stainless steel points pushrod with a flared-end to make contact with the unworn areas of the lobe. The pushrod will need to be installed from inside the block before the cam is installed. IMPORTANT: To prevent seizing of camshaft on pin when engine is ran for the first time, apply plenty of motor oil on cam pin and inside cam before installing cam in engine. This will better protect the parts until crankcase oil reaches them.

Professionally Reground 4,000± RPM Performance Torque Cam -

For Kohler engine models K241/M10, K301/M12, K321/M14, K341/M16 and K361. This particular cam profile design provides more torque (lugging power) and improved engine performance from 3,800 to 4,200 RPM. This cast cam profile has stock lift with increased duration and will pass tech for a stock cam. It will add about 3 more horsepower and 2 ft. lbs. of torque to an average stock engine with more lugging power than the OEM Kohler K361 cam. This cam builds up the compression about 6% more than the K361 cam, and approximately 11% more than the flathead engine cams at around 4,000 RPM. This cam sounds just like an OEM Kohler stock cam. You can't hear the difference out the exhaust. It's perfect for a competing stock pulling tractor or for heavy lawn and garden work. When used for competition pulling, this cam performs best with a set of our BLUE medium performance valve springs (below Ê), reworked and undercut stock size valves, intake and exhaust port runners made bigger, and a bored-out and reworked carburetor. A bored-out venturi and reworked carburetor is when the carburetor is modified for maximum performance for general yard and garden use, and/or for competition pulling. All these performance enhancements needs to be done to increase the airflow in and out of the combustion chamber so the engine can produce more power and torque. If there's any restriction in and out of the combustion chamber, this cam will not be able to perform at 100% efficiency, and the engine will not be able to produce as much power and torque as it is capable of. The duration and centerline of the lobes on this cam helps the engine produce the most power and torque between 3,600-4,500 RPM. At higher RPM, due to the limited duration, no substantial gain in power or torque will result. If the engine is built to the max, tractor is geared correctly and traction is adequate, engine shouldn't bog down much with this cam. It'll keep pumping out the ponies right out the gate! Use with the OEM Kohler 1" base lifters. When reusing lifters, roughen lifter faces with 600 grit sandpaper in an erratic pattern to produce a new wear pattern and so the lifters will rotate slightly with every lift to prevent wear to the cam lobes. Use the recommended break-in oil, too. This cam installs just like the OEM Kohler cam. Just thoroughly lubricate the inside with motor oil, align the timing marks on the gear teeth, set the end-play and valve clearances at .010" for the intake and .014" for the exhaust, and it should be good to go!

FYI: When the cam lobes are reground, metal is removed from the base circle which reduce the diameter of the base circle in order retain maximum lift at the point on the lobe. The ramps on the lobes are also "rounded" to give the cam more duration. The cam grinding machine's grinding stones are about 1" wide, and after the cam grinding process, I have to manually grind metal away from the sides of the base circles so the edge of the lifters won't "ride up" on the ungrounded areas and hold the valves slightly open when they're supposed to be fully closed. I have to do this to every reground cam I have in stock. Some cam grinders apply a phosphate conversion coating (which resembles flat or matte black paint) to the entire camshaft, especially the lobes. This coating is to prevent galling (wear) during the break-in period and it also covers the secondary grinding areas on each side of the base circles of the lobes so they can't be readily easily seen or noticed. Motor oil with high zinc phosphate content will also protect the cam lobes and other internal moving engine parts from wear during break-in. Otherwise, if everything else is set up correctly with your engine, this cam should work fine. There's no need to be concerned when you receive the cam and see the metal ground away. Also, some of the cams I have, the points lobe is slightly worn. (It's hard to find a good used, 100% unworn cam nowadays.) I include a stainless steel points pushrod with a flared-end to make contact with the unworn areas of the lobe. The pushrod will need to be installed from inside the block before the cam is installed. IMPORTANT: To prevent seizing of camshaft on pin when engine is ran for the first time, apply plenty of motor oil on cam pin and inside cam before installing cam in engine. This will better protect the parts until crankcase oil reaches them.

Medium Performance (Blue) Single Valve Spring Set for Kohler engine models K241/M10, K301/M12, K321/M14, K341/M16 and K361. Can also be used in Kohler opposed (flathead) twin cylinder engine models KT17 Series II, KT19 Series II, M18, M20, K482, K532 and K582 for increased performance or competition pulling and with the stamped steel valve retainers below. These springs are more aggressive than OEM Kohler valve springs, but less aggressive than the red valve springs below. Suitable for competition pulling engines only; not recommended for general yard or garden use. Can be easily compressed with a small engine valve spring compressor tool. Designed for the OEM Kohler stock cam or our reground 4,000± RPM torque cam with stock lift in pulling engines running up to 5,000 RPM for quicker valve closing to prevent valve float. (Newton's third law of motion.) Valve float allows the engine to momentarily lose compression, cause fuel to spray out the carburetor and the engine will make a "hunt, hunt" sound at high RPM. As a result, the engine will lose power, and as the weight box on the sled moves forward upon on the tractor, the engine may not be able to recover. These springs can be used with stock size valves, OEM Kohler stamped steel/non-rotator retainers and keepers/locks/collets. Do not use with OEM Kohler valve rotators with these springs! Rotators are thicker, and being these performance springs are much longer (and slightly stiffer) than stock springs (that require rotators), coil bind may result at full valve lift, which could break the cam. Sold as a matched set. One spring is no stiffer than the other. Can be easily compressed with a standard small engine valve spring compressor. Same diameter as OEM Kohler springs. Dimensions: .697" i.d.; .953" o.d.; 2" uncompressed height. Specifications: Seat load: 27 lbs. @ 1.650"; Open load: 70 lbs. @ 1.200"; Coil bind: .920"; Spring rate (lbs/inch): 96. Made by Comp Cams.

New. $10.00 per set of two, plus shipping & handling.

Performance Camshaft for 5,000± RPM Governored Engines -

Fits Kohler engine models K241/M10, K301/M12, K321/M14, K341/M16 and K361 Pulling Engines. This is a more aggressive camshaft than above È. Lobes are hard surface welded on an OEM Kohler cast cam, then professionally precision ground to give it a stock lift (.324"-.330"), but more duration. This cast cam performs best with our BLUE medium performance valve springs (below), reworked and undercut stock size or oversize valves for more airflow, ports made larger and the venturi in the carburetor bored out. If there's any restriction in and out of the combustion chamber, the cam will not be able to perform at 100% efficiency for better engine performance. Due to the increased duration, with an open header pipe, this cam produces a peculiar "bellowing and rumbling" exhaust sound at idling speed and upon deceleration. This cam profile helps the engine produce the most power and torque at wide open throttle operation. If used in a 4,000± RPM engine, no substantial increase in power will result. Can be used with OEM Kohler 1" base lifters. When reusing lifters, roughen lifter faces with 600 grit sandpaper in an erratic pattern to produce a new wear pattern and so the lifters will rotate slightly with every lift to prevent wear to the cam lobes. Use the recommended break-in oil, too. This cam installs just like the OEM Kohler cam. Just thoroughly lubricate the inside with motor oil, align the timing marks on the gear teeth, set the end-play and valve clearances at .010" for the intake and .014" for the exhaust, and it should be good to go! NOTE: If methanol fuel is going to be burned in the engine and the ignition timing advanced more than 25º BTDC, the automatic compression release mechanism on this cam will need to be removed and a high torque starter motor will also need to be used. Otherwise, the timing would be so far advanced, the spark will occur when the compression release opens the exhaust valve. This will cause the engine to be hard to start, if it would start at all. IMPORTANT: To prevent seizing of camshaft on pin when engine is ran for the first time, apply plenty of motor oil on cam pin and inside cam before installing cam in engine. This will better protect the parts until crankcase oil reaches them.

High-Performance (Wide Open Throttle) Camshaft for Hot-Stock and Stock-Altered Pulling Engines -

Fits Kohler engine models K241/M10, K301/M12, K321/M14, K341/M16 and K361 Pulling Engines. This is a much more aggressive camshaft than above È. Lobes are hard surface welded on an OEM Kohler cast cam, then professionally precision ground to give it a stock lift (.324"-.330"), but much more duration (290º). This cast cam performs best with high performance (red) valve springs (below Ê), reworked and undercut stock size or oversize valves for more airflow, ports made larger and the venturi in the carburetor bored out. If there's any restriction in and out of the combustion chamber, the cam will not be able to perform at 100% efficiency for better engine performance. Due to the increased duration, with an open header pipe, this cam produces a loud and attention-getting BOOM, BOOM sound out the exhaust at idling speed, then the sound "smoothes out" at high RPM, and a "bellowing and rumbling" sound upon deceleration. This cam profile helps the engine produce the most power and torque at wide open throttle operation. If used in a 4,000± RPM engine, no substantial increase in power will result.

High Performance (Red) Single Valve Spring Set for Kohler engine models K241/M10, K301/M12, K321/M14, K341/M16 and K361. These are more aggressive than the blue valve springs above È. Suitable for competition pulling engines that run at very high RPM or wide open throttle. Can be easily compressed with a small engine valve spring compressor tool. Designed for cast or steel cams with up to .400" lift in Hot-Stock or Stock-Altered competition pulling engines that run at wide open throttle for quicker valve closing to prevent valve float. (Newton's third law of motion.) Valve float allows the engine to momentarily lose compression, cause fuel to spray out the carburetor and the engine will make a "hunt, hunt" sound at high RPM. As a result, the engine will lose power, and as the weight box on the sled moves forward upon on the tractor, the engine may not be able to recover. These springs can be used with stock size or oversize valves, OEM Kohler stamped steel/non-rotator retainers and keepers/locks/collets. Do not use with OEM Kohler valve rotators with these springs! Rotators are thicker, and being these performance springs are much longer (and much stiffer) than stock springs that require rotators, coil bind may result at full valve lift, which could break the cam.

NOTE: The 7" length camshaft pin is Discontinued from Kohler for their 10-16hp and 18hp OHV K-series engines. It's replaced with a 6-3/4" length [Magnum] pin and a 1/2" diameter steel expansion cup plug. When a 6-3/4" pin is installed in a K-series or Magnum engine, it needs to be driven in 1/4" below the surface of the block (through the flywheel end). Then the 1/2" cup plug needs to be installed to block the hole, prevent an oil leak and keep the pin tight in the tapered hole in the PTO end of the block. Failure to do this could cause the pin to loosen in the tapered hole, and possibly spin with the cam, wearing the holes in the block. And unlike the older K-series engines, being the Magnum bearing plate/gasket doesn't cover the cam pin hole, a 1/2" steel expansion cup plug (with a 6-3/4" pin) or clear RTV silicone adhesive sealant (with a 7" pin) is to be installed in front of the pin to prevent an oil leak. On the older K-series engines, the bearing plate/gasket covers the pin, which seals in the oil. By the way - I've always preferred to use clear RTV silicone adhesive sealant for three reasons: Due to metal warpage (which is unavoidable in most cases), gaskets don't always seal the irregularities between mating metals, especially thin metal covers; being it's an adhesive, it bonds parts together, forming a leak-proof seal; and being it's clear, a thin bead of silicone makes for a clean and professional-looking repair job. It can't be easily seen or noticed between the parts.

Aftermarket Single Cylinder Head Stud Kits for Kohler engine models K241/M10, K301/M12, K321/M14, K341/M16 and K361 with an OEM Kohler or Billet Head. Each kit includes 3/8" diameter x 2" or 2-3/4" length high quality heat-treated studs, grade 8 nuts and hardened flat washers. I can also make the head studs any length you want. The ones that's listed here are the most common lengths. When installed correctly and torqued to specs, head studs provide even torque pressure for better head gasket sealing. Plus, with a thinner cylinder wall with a huge, oversized piston, they help maintain cylinder wall stability and straightness for better ring seal to lessen the loss of compression. Thoroughly tested for several years of continuous use under pulling conditions, for Kohler engines, hardened and heat-treated coarse thread studs, along with grade 8 nuts and washers, works just fine, with no problems. The nuts maintain their torque as long as they're tightened to the correct torque specs. And make sure at least 3/4" of threads are in the block so the cylinder wall will not distort and threads in block will not strip out when the nuts are torqued to specs. Click here for cylinder head bolt torque specs. (Cast iron is weaker than hardened steel.) Also, the flat washers goes under the nuts to distribute even pressure across head. IMPORTANT: As with any threaded stud, apply medium strength liquid threadlocker (Blue Loctite, Permatex or equivalent) on threads that goes in the block to prevent stud from loosening. FYI - When storing an opened, but capped container of liquid threadlocker or Super Glue, store it upright and not laying flat. The [capped] tip will not dry out and clog when stored upright. Thread stud 3/4" into the block. Use a hardened flat washer under nut to distribute load across head and apply motor oil on exposed threads so nut will torque correctly. Torque each nut to 360 in. lbs. or 30 ft. lbs. in correct sequence. Also, stud length is determined by type of cylinder head. The OEM Kohler head with short bolt holes require 2" length studs, the head with tall bolt holes require 2-3/4" length studs. Please indicate length of studs when placing order. An innovative concept by Brian Miller. Accept no copycat parts!

A-1 Miller's Fully Computerized Stuska Water Brake Engine Dynamometer (Dyno) Service with DPM Data Logger Software! For performance testing engines up to 200hp at speeds up to 12,000 RPM. The only engine dyno service in Missouri for Kohler pulling engines! Fully operational and 100% accurate, customers can rent dyno time, fine tune and make adjustments or changes to their engines to gain maximum horsepower and torque, and print-out the results so their tractor(s) will be truly competitive on the track. With an engine dyno, the puller can adjust their engine to get maximum horsepower and torque, and gear their tractor appropriately to have an advantage over the competition. NOTE: A fresh-built engine may not produce full power until it's broke-in. This is when the valves wear-in with the seats to completely seal in the compression. The rings will likely hold the compression, but the valves may leak slightly until they wear into the seats. This is normal for all engines and may take several hours or pulls to happen, then the valves will be able to hold full compression. Lots of pullers tell me after I've built their engines that it seems to pull stronger every time they pull it. Engine Dyno Rental Fee: $50.00 per hour run time from the moment the engine is started. No setup fee for Cub Cadet engines with a 3- or 6-pin/stud clutch driver. An adapter may need to be needed or fabricated for other makes and models of engines. Only engines with the narrow base oil pan can be tested. Engines with the wide base (tall) oil pan cannot be tested at this time.

Magnetic Oil Drain Plugs with Tapered Threads and Square Head. A-1 Miller oil drain plugs have a super strong rare earth/neodymium magnet! Five times stronger than competitor's ceramic (ferrite) magnet and resists demagnetization. Plugs listed below can be used on various other makes and models of transmissions, transaxles, gearboxes and small engines. Tapered threads requires no sealing gasket or sealant, and threads will not strip out when tightened. To avoid cracking oil pan, do not over-tighten! If in doubt, to insure proper sealing and to prevent a possible oil leak, use Teflon®/plumber's thread seal tape on the threads. Universal application. Magnet attracts and removes ferrous metallic wear fragments from the motor oil to reduce engine wear. Sometimes some of the ferrous wear fragments settle to the bottom of the oil pan or engine block and do not drain out with the oil when performing an oil change, even when the oil is hot. The engine will last much longer due to cleaner oil. Magnetic drain plugs are suitable for engines with splash oil lubrication (no oil pump/filter).

Super Strong Rare Earth/Neodymium Magnets for Engines, Transmissions, Transaxles and Gearboxes. Attracts and removes ferrous metallic wear fragments from the lubricating oil inside an engine that does not have an oil pump with an oil filter, or inside a transmission, transaxle or gearbox to lessen wear and noise to gears and bearings. Sometimes some of the wear fragments settle to the bottom of the oil pan or engine block and do not drain out with the oil when performing an oil change, even when the oil is hot. Engine or gears/bearings will last longer due to cleaner oil. Install magnet in bottom of oil pan away from the oil dipper and any moving parts, or in bottom of a transmission, transaxle or gearbox away from rotating gears and any moving parts. Use Krazy Glue, Super Glue, Gorilla Glue, or any industrial strength adhesive to secure magnet in place. These rare earth/neodymium magnets are EXTREMELY strong! Use caution when handling! Can be difficult to remove from a steel or cast iron surface, are very brittle and can break easily if mishandled. An innovative and ingenious concept by Brian Miller because nobody else advertise this trick. Please accept no other advertised copycat products of this kind.

Kohler model K361 Cylinder Head Repairs - FYI - To install a new valve seat in virtually any cylinder head, the head will need to be precision-machined in a fixture with a special valve seat cutting machine, which is similar to a milling machine, then the new seat can be pressed-in. But if the valve guide is worn or loose in the head, it will need to be fixed before the machining of the new seat can be done so the seat will be perpendicular or in perfect 90º alignment with the centerline of the guide. NOTE: I have another automotive machine shop here in Columbia repair my customer's K361 heads because I don't have the required equipment and tooling to perform the repairs. Sometimes they get busy with a lot of other customer's repairs and if you want to send your head to me, it may be some time before they will have it repaired. I can't say when they will have it repaired, but they perform professional, high quality work and they guarantee their repairs. And I don't sell the aftermarket bronze valve seats that are installed in the K361 heads because they are machined from scratch. Due to the molded-in tongue and groove installation of the OEM valve seats by Kohler, the outside diameter of the bronze seats can vary a lot according to how much trouble it is to remove the OEM Kohler valve seats from the head.

Crankshaft Repairs - This includes Briggs & Stratton, Kohler, Tecumseh, etc.

Regrind journal (crank pin) to next undersize. NOTE: Kohler crankshafts can be reground to .030" undersize and still be safe to use with matching undersized replaceable bearing inserts installed in the connecting rod. And all crankshafts, rather if they're automotive or small engine, are checked for straightness before grinding. If they're bent or twisted, sometimes they can be straightened. I also do offset crankshaft grinding to increase the length of the stroke at no extra charge. NOTE: Once installed and in operation, there is no warranty or guarantee of any kind on crankshaft regrinds.

Single cylinder engine crankshafts: $75.00 per journal, plus return shipping & handling.
Two cylinder engine crankshafts: $100.00 per journal, plus return shipping & handling.

"Round Up" Rod Journal(s) and Resize Connecting Rods. The service is for most makes and models of engines when an undersize connecting rod or bearing inserts isn't available, if the crankshaft is worn beyond .010" and needs to be reground again, the journal can be reground to wherever it "cleans up" or is true again, then the connecting rod can be resized so it'll fit the smaller undersize journal with the factory recommended .0025" oil clearance. To resize the rod so it'll fit to a few thousands of an inch smaller diameter crank journal, first, metal is removed from the mating end of the rod cap, then the cap is fasten to the rod. The big hole in the rod is now oblong or "egg shaped." Then the big hole in the rod is honed until it's .002" larger than the diameter of the crank journal. Honing reshapes the hole into a perfect circle again, only smaller in diameter. This works very well and it lasts as long as an ordinary STD size rod and crank journal. This can only be performed on a rod with a good bearing surface. It cannot be done on a burnt or heavily scored connecting rod because too much metal would need to be removed. If you're interested, I will need your crankshaft and connecting rod(s). NOTE - The maximum a connecting rod can be resized to is .005" undersize. If it's resized more than .005", being the big hole in the rod will be made excessively oblong or egg-shaped, which will allow it to less bearing surface contact around the crank journal after being resized, due to the centrifugal force at 3,600 RPM, the big end of the rod could become elongated (metal stretch) and might eventually knock and possibly break. NOTE: Once installed and in operation, there is no warranty or guarantee of any kind on crankshaft regrinds. An innovative concept by Brian Miller, because nobody else advertise this service .

Single cylinder engine crankshafts: $100.00 per journal, plus return shipping & handling.
Two cylinder engine crankshafts: $200.00 per journal, plus return shipping & handling.

Miller's Lawn and Garden Engine Rebuilding and Build-up Services - (Updated 4/22/12) Top of page

Engine Rebuilding Service -

Small engine technology has changed a lot since the Kohler K-series and Magnum engines were made. I can rebuild your lawn and garden engine (or competition pulling engine) with new technological parts so it'll produce more power and last longer than the factory anticipated. I also build engines from scratch and rebuild customer's complete engines from factory stock, to 4,000± RPM governored, to wide open throttle Hot-Stock and Stock-Altered pulling engines. I can build a quality, competition engine for you, or rebuild your engine however you want. Just tell me know how you're going to use your tractor or equipment and I'll build your engine to suit your needs. And if it's required in your club's rules or not, ALWAYS install a safety shield made of adequate thickness and material for each side of the engine fastened to the tractor frame securely in case of connecting rod failure (Murphy's Law), so an innocent bystander or spectator won't be injured or killed from high-speed projected metal shrapnel.

Also, I set the air/fuel adjusters on all carburetors just so the engine will start and run, but because of the altitude level, barometric pressure and air temperature where the engine will be used, the customer will need to make the final bore.) OEM so the engine will run smooth. No carburetor with an adjustable high speed main fuel adjuster comes preset, not even new ones.

Furthermore, just to let you know, although I use the best parts, use caution on choosing the right motor oil to use in your engine. Because the government (tree huggers/Sierra club) is requiring oil companies to lessen the amount of zinc in their motor oils to reduce pollution. Zinc provides a protective coating on internal engine parts and prevents metal to metal contact for proper break-in and it helps the parts last longer. Many auto manufacturers and professional engine rebuilders are upset because of this too, because they have to guarantee their engines for a certain period of time, and many of them take pride in building their engines.

Regarding an Engine Build Estimate -

I am very meticulous in how I rebuild and build engines. If you would like to have me build, rebuild or build-up your engine, I will need a detailed list of exactly what you want done to your engine or a copy of your club's pulling rules regarding the engine requirements before I can give you an estimate on the cost. And if you (the customer), change your mind of how you want the engine built or rebuilt in the middle of a build, I will need to know ahead of time and I will need the changes in writing so I can make the necessary changes to the engine. Otherwise, this will effect how well the engine performs on the track, and it would make me, as a professional engine builder, look bad. It's not a good thing to be afraid that something bad may happen to an engine. Having confidence in an engine makes ya feel good, but having confidence in your engine builder makes ya feel better.

I do not build illegal pulling engines that do not conform to your club's rules! But there are certain other engine builders that offer new pulling engines for sale. BUT, being different pulling associations/clubs have different engine rules and requirements, there is no "one pulling engine that conforms to each and every clubs' rules." Therefore, you may receive an engine that do not conform to your club's rules, and it may be built "above the rules". Meaning it's not legal within your club's rules and is illegal to run in the class you plan to pull it in (cheater engine). Or, the engine in question may be built "below the rules" so it's less competitive as an engine that is built legally to the max according to the rules. But I'll build your engine or an engine for you so it'll produce the maximum horsepower and torque in accordance with your club's rules, not less than what the rules allow. I also rebuild ordinary/stock lawn and garden equipment engines too, such as cast iron and cast aluminum block single- and twin-cylinder flathead, OHV and v-twin Briggs and Stratton, Kohler, Tecumseh and 2-cycle LawnBoy. I've never encountered an engine that I couldn't repair, rebuild or build-up for more power!

Whenever I rebuild or build-up an engine, and if you would like to do so, I do whatever it takes so it'll produce the factory-rated horsepower or the maximum horsepower and torque, and last a long time. I go beyond what the repair manual says to do. I can get all the parts needed, too. I can build your engine so it'll be legal for the class you plan to pull in. And with my engine rebuilds and build-ups, you may not always win, but you'll look good trying! By the way - the surface of the exhaust area of a fresh-built engine may burn off the oil residue for a short time once it gets hot, but it'll stop after a while. It's nothing to worry about. This happens with most rebuilt engines, especially an engine with fresh paint.

FYI - Being I'm the only person to read and respond to all my customer's emails (about 20 or so per day), take my customer's phone call orders (about 20-30 on a nice day with good weather), with customers stopping by my shop, repair and rebuild my customer's parts and engines in my shop, order parts from my suppliers, process orders, package parts then mail customer's parts at my local Post Office, etc., it may take me several months to rebuild an engine. It takes time to perform precision machine work and manual workmanship on a pulling engine and I wouldn't want to do a rush job. I also have to depend on other local machine shops to balance engine parts and perform various machine work that I can't do myself. All this takes time. So please keep this in mind if you decide to have me rebuild/build up your engine. Also, I don't like to rush on my customer's repair jobs. I'm very particular about my work, especially my engine builds. I like to take my time to make sure that everything is right, the engine will run right, produce full power and last a long time. I appreciate for you understanding my situation.

FYI - Used OEM parts in good condition for older Kohler engines are hard to find now, especially the small parts. If the parts don't wear, they tend to get thrown away and then "engine scrappers" sell the parts that do wear on places like eBay. They don't think about people like me, who make a living by "piecing together" or building engines from scratch for a customer. I can purchase new parts from Kohler if they're still available, but that would be cost-prohibitive. I try to keep my engine builds at reasonable prices. - Brian Miller

Things that can be done to a 10-16hp Kohler engine to greatly improve overall engine performance are:

Mill the head about .050" to raise the compression.
Bore the connecting rod offset .020" and install bearing inserts to pop the piston out of the cylinder to raise the compression even more.
Enlarge the intake and exhaust ports to increase the airflow.
Bore-out the venturi and rework the carburetor to increase the airflow even more. NOTE: The venturi in a Chinese-made Kohler-replicated #26 carburetor can be bored out to is 1.09" or 1-7/64", the same diameter as the throttle bore. But the maximum the venturi in a Chinese-made Kohler-replicated #30 carburetor (which actually has a throttle bore diameter of 29.76mm / 1.17") can be bored-out to is 1". If it's bored-out any bigger centered of the throttle bore, being the #26 and #30 are cast in the same mold and machined the same externally, the boring process will likely break through where the fuel inlet port is, rendering carburetor body useless. But the OEM Kohler #30 carburetor can be bored out to 1.2", the same as the throttle bore, with no risk of breaking into the fuel inlet port. A bored-out venturi and reworked carburetor is when the carburetor is modified for maximum performance for general yard and garden use, and/or for competition pulling.
Install stiffer springs for more responsive valve action.
Install a heavy steel flywheel to add extra torque.
Index the spark plug so the open gap face the center of the piston.
Install crank-trigger or flywheel-trigger electronic ignition for a stronger and more stable spark.

Also, all of my customer's pulling engine builds are strictly confidential. This means your competition pulling will not know what goes into your engine!

Competition Pulling Engines Ê

Garden tractor pulling engine technology has changed a lot through the years. I can rebuild your competition pulling engine with new technological parts so it'll produce more power, be more competitive on the track and last longer than anticipated.

The below Ê are high output engines, built and designed for competition pulling only, not general lawn and garden use. No charging system included. 10hp (K241), 12hp (K301), 14hp (K321) or 16hp (K341) Kohler engines built by Brian Miller.

The "Built to the Max" Stock class engines runs at 4,000± governored RPM; has a 9-1/2" cast flywheel with majority of fins removed then dynamically and precision spin-balanced; high torque upper mount gear starter (mounting bolts are below the starter motor); performance valve job with stock size valves; A-1 Miller's reground/torque cam; medium performance valve springs; #26 or #30 Kohler carburetor (depending on engine size) bored-out, reworked and set up for gas; enlarged ports and polished (intake port made larger only if it is smaller in diameter than the carburetor throttle bore); 2nd or 3rd generation cylinder head milled .050"; connecting rod bored .020" offset for piston pop out with bearing inserts. Also included are: flywheel shroud (not chromed), cast iron or aluminum oil pan, bolt-on header pipe and conventional Kohler point ignition system installed with ignition timing preset. And being there is no oil filter on Kohler cast iron block engines, an oil drain plug with a very strong rare earth/neodymium magnet, or a very strong rare earth/neodymium magnet will be glued to the inside bottom of the oil pan or engine base to attract and remove ferrous metallic wear fragments from the motor oil to clean the oil so the engine will last much longer. Because some of the ferrous metal wear fragments settle to the bottom of the oil pan or engine block and do not drain out with the oil when performing an oil change, even when the oil is hot. An innovative and ingenious concept by Brian Miller because nobody else advertise this trick online for a pulling engine.

All A-1 Miller's rebuilt engines will be painted with high quality gloss black unless the customer specifies a different color or no paint at all. When you receive the engine, install it in the tractor, add motor oil to the proper level, install the fuel hose, add fuel, connect the ignition and starter wires, connect the throttle controls, and the engine will be ready to start. Carburetor adjustments will be initially preset, but due to the altitude level, barometric pressure and air temperature, final idle speed, idle air/fuel mixture and high speed air/fuel mixture adjustments may need to be made after the engine is started and warmed up. It'll have no charging system. Use a remote battery charger to recharge the battery before each pulling event.

Competition Pulling Engine Freshening Service Ê This service is for competition pulling engines that have been previously built, and needs the basic parts to revive the power. It is not a complete rebuild. A typical pulling engine will last an average of 25 pulls or 3 years of use. After that, the piston rings become worn, and the engine may lose power when under load and puff gray/blue smoke out the crankcase breather vent and/or the exhaust. When this happens, it's time for a freshening job. Click here for proper break-in (wear-in) oils and procedure for rebuilt engines. Add $110.00 - $152.00 for installation of A-1 Miller's custom crank trigger or flywheel triggered electronic ignition system. (For competition pulling only.) Top of page

NOTES: ± means more or less, depending on how the engine is built in accordance with your pulling club's engine rules and restrictions, and if customer furnish some of the parts. Engines are built as customers order them according to their tractor's make and model. I will need a copy of your pulling club's sanctioning engine rules and requirements so I can build your engine so it'll produce the maximum power and still be legal within its class.

And a 50% deposit may be required on certain engine builds. Balance due upon completion of engine. And I don't offer any chrome-plated sheet metal or chrome-plated header pipes because these parts are cost-prohibited. Please contact me if you're interested in any of the above È parts or services.

A-1 Miller's Fully Computerized Stuska Water Brake Engine Dynamometer (Dyno) Service!

For performance testing engines up to 200hp at speeds up to 12,000 RPM. The only engine dyno service in Missouri for Kohler pulling engines! Fully operational and 100% accurate, customers can rent dyno time, fine tune and make adjustments or changes to their engines to gain maximum horsepower and torque, and print-out the results so their tractor(s) will be truly competitive on the track. With an engine dyno, the puller can adjust their engine to get maximum horsepower and torque, and gear their tractor appropriately to have an advantage over the competition. NOTE: A fresh-built engine may not produce full power until it's broke-in. This is when the valves wear-in with the seats to completely seal in the compression. The rings will likely hold the compression, but the valves may leak slightly until they wear into the seats. This is normal for all engines and may take several hours or pulls to happen, then the valves will be able to hold full compression. Lots of pullers tell me after I've built their engines that it seems to pull stronger every time they pull it.

Engine Dyno Rental Fee: $50.00 per hour run time from the moment the engine is started. No setup fee for Cub Cadet engines with a 3- or 6-pin/stud clutch driver. An adapter may need to be needed or fabricated for other makes and models of engines. Only engines with the narrow base oil pan can be tested. Engines with the wide base (tall) oil pan cannot be tested at this time.

Break-In (Wear-In) Oils and Procedure for Ordinary Rebuilt (Lawn and Garden) Engines -

First of all, full synthetic/organic motor oil will allow an engine to run cooler and last longer. But the rule of thumb for different types of motor oils are: Full synthetic motor oil is mainly for high performance/racing engines that operate at high RPMs for a long time. Synthetic blend motor oil, which is a blend of about 50% organic and 50% petroleum, is for engines that occasionally operate at high RPMs, but also operate at normal speeds. And conventional/petroleum motor oil is safe to use just for engines that operate at normal speeds at all times.

For proper break-in (wear-in) of a new or fresh rebuilt engine, use a high quality conventional (petroleum-based) SAE 30 weight motor oil containing a high zinc content anti-wear additive, such as ZDDP (Zinc dithiophosphate), so the internal moving parts, especially flat tappet lifters and camshaft lobes, will get hot, create a wear pattern and produce a hardened surface. Run an engine with aluminum cylinder wall(s) normally (up to 3,600 RPM) for 2 hours, or for an engine with cast iron cylinder wall(s), run it normally (up to 3,600 RPM) for 5 hours. Don't be afraid to run a fresh-built or freshly rebuilt engine at full governored speed. Just run the engine as usually off and on for 2 or 5 hours to perform lawn and/or garden work as usual. Do not allow the engine to idle at a slow speed (below 1,200 RPM) for a long period of time to break it in! It needs to run at full governored speed (3,200 or 3,600 RPMs) so the oil dipper on the connecting rod can splash the crankcase oil up and thoroughly lubricate/coat critical moving parts. And it's good to set the idle on the high side regardless of the type of oiling system (splash or oil pump) so the flywheel fins will blow more cool air over the engine. Then drain the oil while it's hot. Be sure to tighten the oil drain plug securely after draining the oil. But don't tighten the plug too tight because the oil pan could crack or the threads could strip out. Anyway, either continue to use conventional (petroleum-based) SAE 30 oil, or switch to a quality 10W40 synthetic blend or full synthetic oil for warm weather use. Or use conventional (petroleum-based) 10W40 oil, or 10W40 synthetic blend or full synthetic 10W30 oil during cold winter use. Use no oil additives. Change the oil every 25 hours of engine run time or once a year. Full synthetic oil don't get as hot as conventional (petroleum-based) oil does. It's more slippery and remains cooler than conventional (petroleum-based) oil even after the engine has been in operation for several hours to better protect internal parts for longer engine life.

Break-In (Wear-In) Oils and Procedure for Fresh-Built Pulling Engines -

For proper break-in (wear-in) of a rebuilt or fresh built pulling engine, use a high quality conventional (petroleum-based) SAE 30 weight motor oil containing a high zinc content anti-wear additive, such as ZDDP (Zinc dithiophosphate), which places a protective coating between all internal moving parts, will get hot, create a wear pattern and produce a hardened surface, especially flat tappet lifters and camshaft lobes. Don't be afraid to run a fresh-built or freshly rebuilt pulling engine at speeds it is designed for. Just run the engine normally for 4-5 pulls. Do not allow the engine to idle at a slow speed (below 1,200 RPM) for a long period of time to break it in! It needs to run at full governored speed (3,200 or 3,600 RPMs) so the oil dipper on the connecting rod can splash the crankcase oil up and thoroughly lubricate/coat critical moving parts. And it's good to set the idle on the high side regardless of the type of oiling system (splash or oil pump) so the flywheel fins will blow more cool air over the engine. Then drain the oil while it's hot, and either continue to use ordinary SAE 30 oil, or switch to a quality 20W50 synthetic blend or full synthetic oil. Use no oil additives. Change the oil every 25 pulls or once a year. Synthetic-blend oils get about half as hot as conventional oils. But full synthetic oils don't get near as hot as conventional oils do. It's more slippery and remains cooler even after the engine have been in operation for several hours to better protect internal parts for longer engine life.

If the tractor is geared correctly, the pulling engines I build should not run out of power at the end of the pull. It should spin the tires. But there's some things that needs to be checked after a few pulls as the engine breaks-in and parts wear into each other. For gas fuels, the ignition timing needs to be set at 22º BTDC. And make sure the high speed air/fuel mixture screw is set so the engine runs smooth at high RPM. Also, if a high-output/performance ignition coil is used, it requires two standard capacity (Kohler) condensers/capacitors or one heavy duty, high capacity/performance condenser/capacitor. This is so the coil will produce more voltage. And with a high-output/performance coil, the spark plug gap can be set at .060". With an ordinary coil, it should be set at .035". The valve to lifter clearances may need to be reset at .010" for the intake and .014" for the exhaust.

Furthermore, when a new or rebuilt engine needs to "break-in", what the term "break-in" actually means is the moving internal parts that make contact with each other needs to "wear-in" with each other so they'll produce a wear pattern and last longer. Any new or rebuilt engine, rather if it's for general lawn and garden use or for competition pulling, needs to fully break-in (wear-in) for it to produce full power. Rings don't "seat," they break-in (wear-in), or wear-in with the cylinder wall, and they wear-in quickly. But the valves are the parts that needs to "seat." Being the valve faces and seats have different angles (30º/31º or 45º/46º, respectively), the valve faces needs to wear into the seats to seal in the compression 100%. Wear-in will produce a 30½º or 45½º angle on both the matching valve face and seat. The harder material the valves are made of, the longer it takes for them to "seat" or wear-into the seats. Some pullers tell me that the engines I built for them run better every time they pull them. I remember a few years ago when I performed a valve job on my truck engine. It ran good and produced plenty of power, but I noticed after about 1,000 or so miles, it produced a little more power. I realized that this is because the valve faces wore into the seats, forming a perfect seal. So again, a fresh-built pulling engine will not produce full power the first few times it's ran.

If you bring an engine to me in person, place it in an old automotive tire to keep it from moving around during transportation. And please let me know first so I can expect your arrival. But if you decide to ship your engine to me, I don't need everything on it. Just the parts that can wear and need rebuilding or reconditioning, such as the gear starter, cylinder head(s), crankcase breather assembly, fuel pump and carburetor. I need the oil pan on it too, to prevent any dust and dirt from entering the crankcase after the rebuild. Please remove the sheet metal and PTO clutch/pulley, too. I'll need the flywheel on the engine so I can set the ignition timing. Please send or bring your engine when you're ready to the address below Ê.

To ship your engine to me, first off, do not use the USPS, UPS or FedEx Express! We and our customers have had too many problems with these shippers in the past. Their clumsy "gorillas" or incompetent and uncaring workers have a tendency to damage heavy items, and their insurance never pays off. They claim that the damaged item, which was in their possession, is "not their fault." They are very careless with heavy packages when they handle them. The packages are placed on conveyor-belt systems and they seem to always drop the heavy ones off of the elevated conveyors, which usually destroys whatever is inside them. If you're the kind of person who don't trust delivery/shipping companies (mis)handling your [irreplaceable] high-dollar and fragile merchandise, you can make the long drive to A-1 Miller's shop to personally drop off and/or pick up your engine, transaxle, tractor, etc., for rebuilding or repairs.

If shipping an engine, and if the crated engine weighs no more than 150 lbs., use only FedEx Ground for dependability. The average crated cast iron block Kohler engine weighs just under 150 lbs. Use this website to calculate the shipping cost for your engine: FedEx Rates and Transit Times. Contact your local FedEx Ground ShipCenter for more details and to schedule a pickup or drop off the crated engine at your local FedEx Ground ShipCenter. FedEx Ground is the only reasonably-priced shipping service that I know of for items up to 150 lbs. UPS, US Mail only ship up to 70 lbs. And FedEx Freight would cost almost as much as an engine is worth. If your engine is too heavy to go with FedEx Ground, partially disassemble it and send the lightweight parts in a USPS Large or Medium Flat Rate Box, and then send the main short block with FedEx Ground. This also works better to save money on shipping costs. You can visit A-1 Miller's shop to drop off and pick up your engine to save on crating and shipping charges.

Do not use a cardboard box alone! Crate it well and any other parts with it securely so they won't get damaged or lost in shipping. A sturdy and well-constructed wooden crate can be ordered from: Crates, Wooden Crate in Stock - ULINE. But to construct your own wooden crate, use 2x2's or 2x4's for the frame work, with 1/4" plywood or paneling as outer covering, and a couple of 2x4's or a cut-down pallet on the bottom so a forklift can move it without damage. Make the crate compact as possible so it'll take up less space and be easier to move around in our shop, and to save on shipping charges. Fasten the engine oil pan mounting bolt holes to two sturdy 2x4's on the base of the crate securely with 3/8" diameter bolts. Use extra bracing on the sides and/or across the top of the engine if needed to stabilize it in the crate. For easy removal, PLEASE use Phillips head drywall/sheetrock screws or better yet, use hex head 1/4" lag bolts w/flat washers to fasten everything on and in the crate. And be sure to include a note in a sealed plastic bag with your name, complete and correct postal address, phone number, email address (in case I have any questions) and a detailed description of what you want done, how the engine will be used and any other parts you may need. When the work is completed, I'll contact you with the total including return shipping & handling. For payment options for parts ordered or services performed, or to make a donation to my websites, I accept cash (in person), USPS Postal Money Orders, cashier's checks, business checks, MasterCard, VISA, Discover, American Express (please add 2.5% to the total for the credit/debit card processor's surcharge), Western Union Money Transfer or MoneyGram Money Transfers. (If the engine is for a specific purpose and parts must be special ordered, full payment will be required right after your order is placed or your debit/credit card will be charged for the full amount or as a deposit.) Or you can pay me through PayPal. My PayPal account name is my email address, and be sure to mention in PayPal a description of what the payment is for. If sending a money order or cashier's check, please include a note in the envelope with your name, complete mailing address, phone number and a description of what the payment is for. My mailing address and phone number are below Ê. And I will ship your rebuilt engine/parts to you as soon as I receive your payment.

To ship a transaxle, this is easier. They don't require an enclosed crate. Just place the transaxle on the center of a wooden pallet and stretch wrap (use low-cost ratchet nylon tie-downs) to securely fasten it to the pallet. Use at least 6 layers of stretch wrap or several tie-downs. This should work really well. The shipping weight of a Cub Cadet cast iron case transaxle when strapped to a wooden pallet is approximately 215 lbs.

Warranty: Since the products that are offered in this website are used under extreme high performance conditions, there is no "100% warranty" on most parts, engines or engine rebuilds. If you do have a problem with anything I sold or repaired for you, please feel free to contact me. Parts ordered from this website should be installed and used by persons that are familiar with mechanical parts and their proper use and installation. Consult our garden tractor tips and tricks web pages of the parts for its proper use and mechanical requirements. Customer assumes all responsibility for maintaining products and/or equipment in safe operating condition.

Warranty on our engines and engine rebuilds depend on what goes wrong with the engine. Typically, if the engine is taken care of (regular oil changes, proper ignition timing, valve bore.) OEM and use of correct octane fuel), our engines are quite reliable and will last for many years. So if an engine has been taken care of, I will stand behind our engines for a period of one pulling season or one mowing season.

For a tractor without a driveshaft/clutch assembly, to determine the exact length of the driveshaft, with engine fastened to the tractor frame, measure between the end of the crankshaft threads or bolt head to the input shaft in the transaxle (or creeper drive input shaft), then subtract 1/4". This will allow an 1/8" clearance on each end. Driveshafts for hydrostatic drive Cub Cadets are also available below. Ê IMPORTANT: Before installing the driveshaft/clutch assembly in the tractor, if the drive plate has a bronze pilot bushing, apply clean lubricating grease inside the bushing and on the front of the driveshaft. Because if it's installed dry, the driveshaft may not release, it can bind up and wear both the bushing and driveshaft. No grease is required on the driveshaft if a radial ball bearing is installed the drive plate.

Replaces Cub Cadet part #'s IH 140079 C1 (models 680, 1210, 1211, 1282), 738-3061 (782D, 882, 1512), 738-3011 (models 682, 782, 784, 982, 1541, 1710, 1711, 1712, 1810, 1811, 1812, 1860). Please specify model of tractor when ordering. Spiral pins sold separately. (Scroll down.)

Replacement Driveshaft Spiral Pins. Each made of hardened carbon steel. Minimum Rockwell hardness is C42. Pins are heat treated. NOTE: The driveshafts with or without a creeper drive unit use the same number of spiral pins. There's two for the pressure plates, one at the end of the main pressure spring, and two in the rear round Coupler. But instead of using a spiral pin that connects the round Coupler to the input shaft in the transaxle, a grade 8 bolt w/locknut can be used instead for much easier installation and removal.

3/8" Diameter x 1-1/2" length Spiral Pins for OEM 3-pin clutch drive plate and [narrow frame Cub Cadet] drag link steering arm. Hardened carbon steel. Minimum Rockwell hardness is C42. NOTE: The holes in the drag link arm and spindle may need to be drilled exactly to 3/8" (.375") for this pin to fit. $3.00 each, plus shipping & handling.

Clutch Drive Studs w/Nuts and split lock washers for MTD Cub Cadet 3-pin clutch drive plate or to convert a 3-pin clutch drive plate into a 6 pin clutch driver. Each stud below made of hardened steel.

NOTE: Adding three additional clutch drive studs is something that must be performed with precision machining. To install three additional clutch drive studs in the OEM clutch drive plate and have them perfectly aligned with the OEM drive pins and the three extra holes in the clutch disc, and to prevent the pins from being out of balance (out of circle) and to prevent wobble, the holes in the plate (and clutch disc) will need to be drilled using a Super Spacer or Rotary Table that's fastened to the table of a milling machine. Each hole must be drilled precisely at 2.5625" out from dead center and spaced exactly at 90º from the original drive pins. This will allow the 3 extra drive studs (and holes in clutch disc) to be positioned in exact alignment with the OEM pins. Just like the wheel studs on an automobile. If you want, I can professionally install three extra drive studs in your clutch drive plate and drill three extra matching holes in your clutch disc for $45.00 labor, which includes the 3 drive studs, plus return shipping. I will need your clutch drive plate and clutch disc, too.

IMPORTANT - It is highly recommended that both pressure plates be trued-up (to reduce vibration) and resurfaced (machined) in a metal lathe to remove warpage until perfectly flat or severe clutch slippage may result! Because new OEM Cub Cadet pressure plates are made of stamped steel and are not machined whatsoever. This means they are not perfectly flat and they wobble from the factory. If used pressure plates have not been resurfaced before, then chances are, they'll still be thick enough after being resurfaced. Always remove the minimal amount of metal to retain maximum thickness so they will not warp when hot.

FYI - About 90% of the fiber material in clutch discs will chip off were the holes are due to the following reasons:

New Machined Aluminum Clutch Disc with (6) 13/32" drive holes for a 3- or 6-pin drive plate. This is an alternate and direct replacement for the fiber material clutch disc. Made of the highest quality 6061 alloy; medium-grade hardness aluminum available. The 1-1/8" center hole in disc is bored dead center, and the circumference is turned true in my metal lathe, then the 6 drive holes are precision-drilled using my 8" super spacer with a 6-notch masking plate on the table of my milling machine. Unlike some of my competitor's copycat part, the drive holes in my aluminum clutch discs are drilled 13/32" for less clutch disc noise/rattle and less chance of breakage to the drive pins/studs. An ingenious and innovative concept by Brian Miller, because nobody else originally advertised this part online.

Clutch Disc Anti-Rattle Spring. Reduces noisy fiber or aluminum clutch disc rattle on drive pins/studs. Although one spring may be sufficient to reduce clutch noise, it may be necessary to install three springs (one for each pin/stud) for 100% reduced clutch noise. Can be used on fiber or aluminum clutch discs. NOTE: Recommended for up to 4,000 RPM engines. Not for use on high RPM or wide open throttle competition pulling tractors due to normal engine harmonic vibrations that travels out into the clutch assembly, this can create the possibility of the spring(s) becoming dislodged, which could become a hazardous airborne projectile if clutch is not properly shielded 360º. So if possible, install these springs with the coil between the clutch disc and drive plate, opposite that is shown in the picture to the right, to prevent them from coming off. OEM Cub Cadet part # 932-3018.

Lubricating Sleeve with Grease (Zerk) Fitting for use with the short clutch release/throw-out bearing above È. When reassembling clutch parts on narrow- or wide-frame Cub Cadet driveshaft, a thin coat of lubricating grease between the clutch release/throw-out bearing and driveshaft is all they receive for the life of the driveshaft until it's disassembled again for rebuilding. This part allows for easy lubrication and saves wear to driveshaft from sliding friction due to movement of clutch release/throw-out bearing, especially with a heavy (red or yellow) main pressure spring. Also allows for easier and smoother clutch pedal depression. Sleeve installs between clutch release/throw-out bearing and main pressure spring with grease (Zerk) fitting toward the spring for easier access. Heavy wall tubing measures .626" i.d. x 1" o.d. x 3/4"± length. Third spiral pin hole or split clamping/locking collar(s) behind pressure spring may need to be relocated 3/4" further back on the driveshaft. IMPORTANT: Lubricate driveshaft through grease (Zerk) fitting in bushing with automotive grease gun once a year. An ingenious, thoroughly researched and innovative concept invented by Brian Miller, because nobody else advertise the use of this part.

Teasing Spring and Thrust Washer Kit. Fits all clutch-drive Cub Cadet garden tractors, and Cub Cadet models 1250, 1450 and 1650 equipped with a hydrostatic disconnect attachment. Thrust washer goes between rear pressure plate and teasing spring. The washer prevents end of teasing spring from "catching" in the slot of the rear pressure plate upon clutch engagement. This twists the spring a few thousandths of an inch each time the clutch is engaged, which creates metal fatigue in the spring and could cause it to eventually break, even with the cup/spacer below. (Another factory flaw that happens many years later.) An original, ingenious, thoroughly researched and innovative concept by Brian Miller, because nobody else advertises the use of this washer with the teasing spring. Please accept no other advertised copycat products of this kind.

Thrust Washer Only. .050"± thickness. $1.00 each, plus shipping & handling.
Teasing Spring Only. OEM Cub Cadet part # 932-3017. $6.20 each, plus shipping & handling.

Cup/Spacer for Teasing Spring. Made specifically for Cub Cadet garden tractor models 582, 800, 1000, 1200, 1535, 1604, 1606 and 1806. Also fits Cub Cadet models 1250, 1450 and 1650 equipped with a hydrostatic disconnect attachment. Overall length: .605". NOTE: Do not install this part in a narrow frame Cub Cadet garden tractor! It will position the throw-out bearing further back on the driveshaft and not allow the clutch to fully disengage or disengage at all. IMPORTANT: When installing this part on driveshaft, the wide/flared-end faces forward and the narrow end goes against the throw-out bearing. And do not install this part on a driveshaft that originally did not come with it. It will set the throw-out bearing back too far, making correct throw-out bearing to release lever clearance adjustment impossible and the brakes may not work.

OEM Cub Cadet part # 911-3040. $18.45 each, plus shipping & handling.

Cup/Spacer for Teasing Spring. 2" overall length; made specifically for Cub Cadet garden tractor model 1050. Comes with installed grease (Zerk) fitting. IMPORTANT: When installing this part on driveshaft, the wide/flared end faces forward and the narrow end goes against the clutch release/throw-out bearing. Discontinued from Cub Cadet. Replaces Cub Cadet part # 711-3282.

5/8" i.d. Split clamping/locking collars.

With the drilled 3rd spiral pin hole not present in the driveshaft, this part stiffens the driveshaft in the middle 100%, and it helps prevent driveshaft breakage at 4,000 RPM (without a pillow block bearing and support brace installed), and when used with a pillow block bearing and support brace, this prevents the driveshaft from "wobbling around", which could break at higher RPMs or at wide open throttle. Position collar at 9-1/4" from front of driveshaft. This will compress the main pressure spring to 4-1/2" once installed and clutch assembly is reassembled (with the clutch/brake pedal not fully depressed). Can also be used on front of the IH Cub Cadet "Original" driveshaft to prevent driveshaft from moving rearward when clutch pedal is depressed. Has two Allen head screws that holds the clamp together and provide a very tight uniform 360° grip around the driveshaft. NOTE: With a stainless steel driveshaft, it's best to use two split clamping/locking collars or a pillow block bearing with an eccentric locking collar because just one split collar might slip on the "slick" and hardened surface of stainless steel.

Two-Piece clamping/locking collar. $3.00 each, plus shipping & handling.
One-Piece clamping/locking collar. $7.50 each, plus shipping & handling.

Driveshaft Center Support Pillow Block with self-aligning 5/8" ball bearing and high quality cast iron housing. Center to center of mounting holes: 3-3/4". Use with support brace below Ê. IMPORTANT! Required only for competition Cub Cadet pulling tractors with an engine that run at high RPM or wide open throttle to prevent driveshaft wobble and possible breakage. Install just behind main pressure spring on driveshaft to stabilize driveshaft. See pictures of correct installation below. Ê [Return to Previous Section, Paragraph or Website]

Pillow block bearing w/set screw collar. $20.00 each, plus shipping & handling.
Pillow block bearing w/eccentric locking collar. $30.00 each, plus shipping & handling.

Support Brace to be used with either Pillow Block Bearing above È. Made of 1/8" thickness x 2-1/2" width angle steel with holes drilled. Super tough, will not break, even under severe vibration. IMPORTANT! Before installing this brace between Cub Cadet frame rails, first install pillow block bearing w/housing on assembled driveshaft, connect driveshaft to transaxle and engine, tighten engine mounting bolts to tractor frame, then fasten this angle brace to pillow block bearing. This will guarantee the pillow block bearing is in perfect alignment and centered with the driveshaft. Otherwise, the driveshaft will be noisy. Then permanently weld angle brace to tractor frame rails. See correct installation below. Ê A product by Brian Miller, because nobody else advertise this part online.

For a custom-length coupler, exact locations where the spiral/roll pin holes need to be drilled are required. To find the location of the spiral/roll pin holes, install the driveshaft in the tractor with the engine fastened to the frame with a couple of bolts, make sure the clutch disc is midway on the drive pins, then measure precisely from the rear spiral/roll pin hole on the driveshaft to the spiral/roll pin hole in the input shaft in the transaxle, then add 3/4" for the overall length of the coupler. NOTE: The 3" aftermarket coupler is used only for competition pulling tractors with a shortened driveshaft so the input shaft/pinion drive gear can be changed to vary the ground speed of the tractor. And when ordering, please specify model of Cub Cadet, overall length and spiral/roll pin hole locations.

Angled/L-Shaped/90º Pivot Pin w/Cotter Pin for Cub Cadet clutch release lever/hanger brackets. This is an alternative to using the OEM straight clevis pin or a grade 8 bolt and lock nut. An angled/L-shaped pin prevents the holes in the release lever and hanger bracket from wearing oblong due to constant spinning of the OEM straight clevis pin while the tractor is in operation. Lessens clutch noise, maintains clutch adjustment, and allows for smoother clutch operation. Made of 3/8" diameter mild steel. For all clutch drive Cub Cadet models: 70, 71, 72, 73, 86, 100, 102, 104, 106, 108, 122, 124, 126, 128, 580, 582, 800, 1000, 1050, 1200, 1535, 1604, 1606 and 1806. Due to various lengths, please specify model of Cub Cadet when ordering. An original, ingenious, thoroughly researched and innovative concept invented by Brian Miller, because nobody else advertise the use of this part. Please accept no other advertised copycat products of this kind.
