Everything in this website is up to date and most parts should still be available. Updates are made only when there's a change in the listing for a part or product. If a part or product is no longer available or have been discontinued, I remove it from this website. I shop around for the highest quality parts with the most reasonable prices available, so prices are subject to change without notice. I can also get a lot of other parts that's not listed on my websites. Just let me know what you need and I'll see if I can get it at a reasonable price. And the condition of these parts are brand new, first line products, unless otherwise stated. No seconds or blemishes being pawned off on unsuspecting customers. Optimized for 1024 x 768 screen resolution. To search for a word or phrase in any of my websites, with Internet Explorer 6.x, or Google Chrome, press CTRL+F to open the Find dialog box.

To place an order, please call either number 1-573-256-0313 (shop) | 1-573-881-7229 (cell) or send an email to pullingtractor@aol.com (below Ê ) with a description of the parts, products or services you need including your zip code and I'll respond with the total amount with shipping and handling. Because as of now, my websites are not set up to accept orders online. And I apologize, but I have no printed material (catalog) available at this time. You'll have to print out my websites. I contacted some book publishing companies and they said being all my information is online at no charge, they don't think the books would sell well.

"Perfection takes time. If it's worth having, it's worth waiting for." - Brian Miller

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.

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. Fax: 1-573-449-7347. 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. If you're the kind of person who don't trust delivery/shipping companies (mis)handling your high-dollar and fragile merchandise, you can always make the long drive to A-1 Miller's shop to personally drop off and/or pick up your engine, transaxle, tractor, etc. "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, I accept cash (in person), Postal money orders or cashier's checks made out in my name, MasterCard, VISA, Discover, American Express and Western Union Money Transfer. (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 and 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 always make the long drive to A-1 Miller's shop to personally drop off and/or pick up your engine, transaxle, tractor, etc.

Ship to Canada and Worldwide þüý -
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.


Official PayPal Seal We Accept PayPal, Visa, MasterCard, American Express & Discover Credit & Debit Cards Western Union - Send Money - Money Transfer - Find Location - Transfer Money
(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. PayPal protects your financial privacy and security. With PayPal, privacy is built in. It's a way for you to pay without exposing their financial information.

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.

The bottom main fuel adjuster is not an OEM Kohler part and not a modification by Kohler. It 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 fuel 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/nozzles (emulsion tubes), which can be very difficult to remove.) The carburetor must be converted to the bottom adjuster when using this part. Fits all Carter/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 (flathead) twin cylinder flathead engines to "fine tune" the air/fuel mixture.

This part is professionally CNC machined in the USA and not available from Kohler. NOTE: When rebuilding a plain, stock Carter/Kohler carburetor, there is no need to remove the main jet/nozzle. If it won't come out, then don't worry about it. All that has to be done to make sure the bottom hole and the side holes on it are open. To check if the side holes are open, simply spray carburetor cleaner or WD-40 or carburetor cleaner (in an aerosol spray can) through the small hole just under the choke plate and observe if the spray exits out the main jet/nozzle inside the throttle bore and bottom of carburetor. But if modifying a carburetor to bore the venturi, the main jet/nozzle must be removed. Click here for how to remove the main jet/nozzle.

Kohler Anti-Backfire Solenoid Kits.

Kohler's Magnum Fuel Solenoid 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.

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/Kohler and Walbro carburetors don't come with a throttle shaft bushing installed from the factory. A bushing (see below Ê) must be installed when the throttle shaft is worn and loose in the carburetor, or a 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 #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 bushingBronze Throttle Shaft Bushing for Carter #16, #18, #20, #22 carburetors with a counterbore that's used on Kohler engine models K90/K91, K141, K160/K161 and K181, as well as other makes and models of engines that use the same carburetor. Dimensions: 7/32" i.d. x .407" o.d. x 1/8" height. NOTE: Apply clean motor oil or automotive grease on throttle shaft before installing for smooth throttle operation and less wear to shaft, bushing or carburetor body. And some later Carter carburetors do not have the counterbore to accept this bushing. If there's no counterbore, then if the shaft hole is not severely worn, a new throttle shaft (see below Ê) can be installed. Go here to learn how to professionally remove Carter/Kohler throttle or choke plate retaining screws without breaking them off. But if the shaft hole is severely worn, it will need to be slightly enlarged to match a fabricated oversized throttle shaft made of mild steel. The original lever will need to be ground off the old shaft and welded onto the new shaft. I offer this service, too. (see below Ê) No Kohler part number available for this bushing.

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/Kohler #26, #28, #30 and early Walbro #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 and a felt or foam seal to keep out dust and dirt (available below Ê), 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 and 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/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 or automotive 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.

If the throttle and/or choke shafts and/or shaft holes are worn in a K482, K532 or K582 carburetor, if the holes aren't worn beyond for reuse, I make a new throttle shaft for it. But if the holes are worn too, and being the metal is too thin on one side for installation of a bushing, the shaft holes will need to be enlarged a few thousandths bigger than 1/4", and a steel rod that's slightly bigger than the enlarged holes (for a slip-fit) will need to be fabricated for use as a throttle shaft. I then align and weld the OEM throttle lever to the new shaft. I also install a foam seal on the throttle shaft and a thin, hardened steel thrust washer next to the throttle plate to prevent it from wearing against the carburetor body. And I install a new overhaul kit. I've performed this type of repair many times with excellent results. I offer this repair service. If interested, I will need for you to send me your carburetor. And for dimensional measurements, I will need the complete carburetor with the throttle and choke shafts with the levers and the throttle and choke plates. I will fabricate new shaft(s), and install the lever(s) on the shaft(s), and install the throttle and/or choke plates on the shafts in the carburetor. FYI - Bearing bronze is very hard, porous, absorbs oil and lasts a long time when lubricated regularly and used as a bushing. Brass, on the other hand, is soft, non-porous and wears quickly when used as a load-bearing bushing or shaft.

IMPORTANT: For the K241/M10, K301/M12, K321/M14, K341/M16 and K361 choke plates below Ê - If the wrong choke plate is used or mismatched with any particular size engine, due to the size and number of holes in the plate, the engine may become flooded too easily, resulting in either hard starting or a fouled spark plug. Or the engine may not receive enough fuel, resulting in hard starting. (None of these will happen with my remote fuel primer kit.) Also, Walbro and Carter/Kohler choke plates are not interchangeable.

Universal Small Engine Remote Fuel Primer Kit. Safe to use and works flawlessly! A must for a competition pulling tractor engine with no choke! 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 remote solid wire choke cable and/or bent choke plate, or messy "hand choking" of 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. Kit includes primer bulb assembly w/mounting nut and barbed hose fitting, 3' of 1/8" i.d. x 3/16" o.d. clear vinyl hose, spring-loaded hose clamp, loop-type clamp and 1/8" diameter x 1" length brass tube.

New Bronze Governor Shaft Bushings with or without a snug-fitting Neoprene Rubber Oil Seal installed in machined counterbore to keep dust and dirt/debris out (which wears the bushing) and prevent film of oily mess on side 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. NOTE: When ordering, please specify part number of bushing or engine model and specification numbers.

12 Volt Low Pressure Electric Fuel Pump Installation Kits. Low pressure, small and compact. Convert from gravity feed, or replace faulty vacuum-operated/pulse-type or mechanical fuel pump (with a deteriorated diaphragm that can seep gas in 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 and 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 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 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 winter-time or 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 battery positive (+) post or a terminal on the ignition switch that connects to the battery positive (+) 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/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 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.

  • Completely disassemble carburetor, resurface mounting flange and choke end on a belt sander or sanding disc to remove warpage and restore flatness to prevent a vacuum leak, and then soak the carburetor body and parts in my ultrasonic cleaning machine. NOTE: The only way to remove all the paint from the carburetor body is to sandblast it. But sandblasting can allow tiny fragments of sand to become embedded in the fuel passageways, causing problems later.
  • Enlarge the lower hole on the high speed needle adjuster so engine will start quicker and idle better. An original, ingenious and innovative concept by Brian Miller, because nobody else advertise this repair service.
  • Install new overhaul kit.

  • The idle speed and air/fuel mixture adjustments will be preset on the carburetor just to get the engine running, but due to the altitude level, atmospheric/barometric pressure and air temperature where the engine will be used, final idle and high speed air/fuel mixture adjustments will need to be made by the customer so the engine will run smooth.

IMPORTANT: When sending your carburetor to me, please package it and all parts to it securely in one sealed zip-lock sandwich bag to prevent loss of parts in shipping, and to prevent the odor of gas from escaping the package. If the odor of gas is still present from outside the package, apply air freshener on the carburetor to disguise the smell of gas. Because the US Postal Service or other delivery services will not deliver any packages that smell like gas. Also, be sure to include a note in the package with your name, complete and correct postal address, phone number (in case I have any questions), a description of what you want done, how the engine will be used and any other parts you may need. I will contact you when the carburetor (and list of parts) are ready to be sent back to you.

If the throttle and/or choke shafts and/or shaft holes are worn in a K482, K532 or K582 carburetor, if the holes aren't worn beyond for reuse, I make a new throttle shaft for it. But if the holes are worn too, and being the metal is too thin on one side for installation of a bushing, the shaft holes will need to be enlarged a few thousandths bigger than 1/4", and a steel rod that's slightly bigger than the enlarged holes (for a slip-fit) will need to be fabricated for use as a throttle shaft. I then align and weld the OEM throttle lever to the new shaft. I also install a foam seal on the throttle shaft and a thin, hardened steel thrust washer next to the throttle plate to prevent it from wearing against the carburetor body. And I install a new overhaul kit. I've performed this type of repair many times with excellent results. I offer this repair service. If interested, I will need for you to send me your carburetor. And for dimensional measurements, I will need the complete carburetor with the throttle and choke shafts with the levers and the throttle and choke plates. I will fabricate new shaft(s), and install the lever(s) on the shaft(s), and install the throttle and/or choke plates on the shafts in the carburetor. FYI - Bearing bronze is very hard, porous, absorbs oil and lasts a long time when lubricated regularly and used as a bushing. Brass, on the other hand, is soft, non-porous and wears quickly when used as a load-bearing bushing or shaft. Click here to learn how to professionally remove Carter/Kohler throttle or choke plate soft brass retaining screws without breaking them off. An innovative concept by Brian Miller, because nobody else advertise this repair service.

Rebuilt, reworked, modified and blueprinted only for high performance use, #26 Carter/Kohler carburetors. These carburetors have been internally modified to outperform a stock OEM carburetor under heavy pulling load and will not run lean while going down the track. Will pass tech with any club. The venturi in these carburetors can be bored so they'll have either a 7/8", .995" or 1" venturi or a 1.07" straight-through throttle bore for high RPM operation, setup for gas, E85 or methanol fuels, whatever your club's sanctioning rules allow or whatever you desire for all-out engine performance. These carburetors are completely disassembled, then thoroughly cleaned. All fuel passageways cleared, new parts and if necessary, a new throttle shaft and/or bushing are installed. The idle speed and air/fuel mixture adjustments will be preset on the carburetor to get the engine running, but due to the altitude level, atmospheric/barometric pressure and air temperature where the engine will be used, final idle and high speed air/fuel mixture adjustments will need to be made by the customer so the engine will run smooth.

NOTE: These carburetors are designed for use on Stock, Hot-Stock, Stock-Altered or Missouri Super Stock pulling engines with a stock size or an oversize intake valve. Also, a high performance carburetor is designed solely for a high performance engine. Just bolting on a high performance carburetor is not how to gain more power and torque for a stock engine. If your engine is not a high performance engine built to race specs, then it will not benefit from a high performance carburetor whatsoever. These carburetors will not allow a stock "factory-built engine" to produce lots of power just by bolting it on. Everything in the engine MUST work together to prevent air restriction or a "bottleneck" to slow down air flow. With a bigger carburetor, the engine needs to breath A LOT more air in and out of the combustion chamber. This means the intake and exhaust port runners will need to be made bigger, the valves reworked for more airflow, a bigger cam will need to be installed, and the ignition system will need to be up to standards.

Also, these carburetors are "built to order." So when placing an order, please specify if your engine has a factory stock size or oversize intake valve, if you want it with a straight-thru throttle bore (no venturi) or a .995" or 1" venturi, if the engine is going to turn at 4,000± RPM, high RPM or wide open throttle, and if you want the choke plate/shaft installed.

All rebuilt carburetors that I service and sell come with a 30 day workmanship warranty and are guaranteed to be free of defects. Technical support comes with part of the warranty.

Ignition Points used on Kohler, Tecumseh and Clinton engines. Fits Kohler engine models K90/K91, K141, K161/K160, K181, K241, K301, K321, K330/K331, K341, K361, KT17, KT17 series 2, KT19, KT19 series 2, K482, K532 and K582 with magneto or battery ignition (use with mounting bracket). Also replaces: Tecumseh part #'s 32011, 32011A, used on engine models HH80, HH100, HH120 with battery ignition (use without mounting bracket); and Clinton engine models 414, 418, 420, 422 (use without mounting bracket). NOTE: Apply clean motor oil or automotive 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.
  • High quality aftermarket points with mounting bracket. $9.00 each, plus shipping & handling.
  • OEM Kohler points with mounting bracket, part # 47 150 03-S. $14.30 each, plus shipping & handling.
  • Install Hex Socket (Allen) Head Cap Screw and split lock washer (below Ê) in points w/bracket above È, add .50¢.
  • NOTE: The electronic transistorized ignition modules (below) can be substituted for the points and condenser/capacitor for a stronger and more stable spark, quicker starts, and virtually trouble- and maintenance-free magneto ignition system.


Hex Socket (Allen) Head Cap Screw w/split lock washer to replace OEM 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 accurately 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, do not over-tighten adjustment screw! An original, ingenious and innovative concept by Brian Miller.
  • .50¢ each, plus shipping and handling.
  • Install Hex Socket (Allen) Head Cap Screw and split lock washer in points w/bracket above È, add .50¢ to price of points.


9/64" Hex (Allen) L-Wrench. Use with hex socket (Allen) head cap adjustment/clamp screw (above È) in Kohler points to accurately set ignition timing with less effort in hard to reach places (such as Cub Cadet) and securely tighten screw so points will not slip out of adjustment. Wrench measures 7/8" wide x 2-1/2" length. Made of high strength black alloy steel. NOTE: Due to risk of stripping threads, do not over-tighten adjustment screw!
  • $3.00 each, plus shipping and handling.


Screws and split lock washers for mounting of ignition points and points cover. Phillips and Socket Head (Allen) screws make for easier fastening of points and points cover to engine block in hard-to-get places. Each: 10-24 UNC x 3/8" thread length. Slotted head points and cover mounting screws TIP: Apply dab of grease in head of slotted head screw when installing to keep it from falling out of screwdriver.

  • Used and in excellent condition. Slotted head screw with integrated star lock washer. Discontinued from Kohler. OEM Kohler part # X-131-1-S. .25¢ each, plus shipping and handling.
  • New Phillips head and split lock washers. $1.00 per pair, plus shipping and handling.
  • New Socket Head (Allen) cap screws and split lock washers. $1.00 per pair, plus shipping and handling.
GM (Chevrolet) V8 adjustable ignition points that can be used on the Kohler K-series 10hp-16hp and opposed (flathead) twin cylinder engines. NOTE: The "Chevrolet" ignition points are actually made for the 1959-'74 American Motors, 1957-'73 Buick, 1956-'73 Cadillac, 1965-'74 Checker, 1957-'73 Chevrolet, 1956-'73 GMC, 1957 Hudson, 1957-'74 International, 1966-'74 Jeep, 1957 Nash, 1956-'73 Oldsmobile, 1957-'73 Pontiac, and 1960-'66 Studebaker vehicles with a V8 engine and Delco-Remy distributor. But 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. Points have a stiff spring for quick response at high RPM or wide open throttle. Due to the inability to completely seal (cover) the point contacts from dust and debris, these are for competition pulling only, and not for general lawn and garden use. And being the bracket for the GM points and the GM points themselves are much larger than Kohler points and bracket, the OEM Kohler points cover will not fit over the GM points and mounting bracket.
  • GM (Chevrolet) points only. $10.00 each, plus shipping and handling.
  • Stainless steel mounting bracket for Chevy points w/mounting screws. (Limited supply.) Protective cover not available. $15.00 each, plus shipping and handling.
Ignition Points. Fits Kohler engine models K660 and K662 with WICO magneto ignition. NOTE: Apply oil or grease on the hinge pin before installing points so the hole will last longer. When it's dry, it'll wear prematurely, effecting ignition timing, resulting in loss of engine power. Discontinued from Kohler. Replaces Kohler part # 240611-S. Also replaces Wisconsin part #'s 28-1AT-3076-ES, X5996 and X6942.
  • High quality aftermarket. $16.00 each, plus shipping and handling.
  • NOTE: The Electronic Transistorized Ignition Modules (below Ê) can be substituted for the points and condenser/capacitor for a stronger and more stable spark, quicker starts, and virtually trouble- and maintenance-free magneto ignition system.
Condensers/Capacitors for battery powered ignition systems. Used on Kohler engine models K90/K91, K141, K161/K160, K181, K241, K301, K321, K330/K331, K341, K361, KT17, KT17 series 2, KT19, KT19 series 2, K482, K532 and K582. Condensers/capacitors listed below Ê includes clamp. NOTE: If an engine idles well, but runs erratically above idle, like it hits and misses, pops and backfires, then chances are, it needs a new condenser/capacitor. Click here to hear what an engine with a faulty condenser/capacitor sounds like. Also, use two standard capacity (Kohler) condensers/capacitors or one high-capacity/performance condenser/capacitor with a high-output/performance ignition coil so it will produce more voltage (full coil saturation). (When using two condensers/capacitors, connect each condenser/capacitor to the negative (–) terminal on the coil, or to the wire going to the points, and make sure each condenser/capacitor is grounded.) IMPORTANT: Always install a condenser/capacitor with the wire or terminal facing down so rain water and/or when washing off engine, water will not enter inside condenser/capacitor, ruining it.
  • Standard capacity condensers/capacitors. Designed to be used only with standard-output/stock ignition coils. Will not work with a distributor-driven ignition coil. Each measures: .665" diameter x 1.250" length x 3-1/2" wire length.

NOTE: The magneto coil wrapped with varnish-coated paper (Kohler part # 210293), and the ignition stator assembly and ring shown above È are no longer available 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.

Universal Magneto Ignition Coil for various engines with points, condenser/capacitor and coil under the flywheel.

Spark plug wire molded in coil. Spark plug wire length: 17". 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 even better when used with a Universal Solid State Ignition Module (see below ). The short wire on the coil is for ground, the longer wire connects to the points and condenser/capacitor, and may need to be made longer depending on your application. Click here for identification and wiring diagram for this coil. Dimensions: .400" x .400" square hole (across flats) x 1.630" o.d. x 2.020" length (including hump for spark plug wire). If laminations on your stator are too big for the hole in this coil, they can be ground or filed smaller so coil will fit snug, then bend one laminate over to retain coil, or if the laminations are too small, thin strip(s) of steel can be added so coil will fit snug, and coil should produce a strong spark. 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 for a strong spark. Do not enlarge the hole in the coil! How magneto coils produce a spark. NOTE: The electronic transistorized ignition modules (below ) can be substituted for the points and condenser/capacitor for a stronger and more stable spark, quicker starts, and virtually trouble- and maintenance-free magneto ignition system.

Universal Magneto Electronic Transistorized Solid State Ignition Modules -

  • Upgrade the magneto ignition system on virtually any engine with the latest technology! Do away with the points and condenser/capacitor, and install a solid state ignition module. It should be the end of the ignition problems. The 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 points pushrod hole (Briggs & Stratton or Kohler engines).
  • There is absolutely no difference how these modules work. They all work the same. Kind of like the difference between the Chevy, Dodge and Ford vehicles. These are universal and high performance. They improve engine performance by stabilizing the spark, much like crank trigger ignition does, except the detector/trigger target is the magnets on or underneath the flywheel and the coil laminations. These modules have a durable die-cast aluminum housing. They all produce a strong spark even at cranking speeds, allows the coil to produce 100% voltage. 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 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 points and condenser/capacitor with one of these solid state modules. If the engine ran, then the coil is obviously good.
  • Works only with magneto type ignition coils originally connected to contact points and a condenser/capacitor. They will not work with solid state ignition (CDI) coils, battery-powered ignition coils or with flywheels having a ring of magnets installed internally to which the ignition coil (mounted underneath flywheel also) operates off of, such as the bigger aluminum block Tecumseh engines (8hp and up). (With the module, as each magnet passes 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.) 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 passes 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 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 passes the coil laminations the moment the points open. But with no points, the magnet still pass the coil laminations at the same moment, which sends an electrical current through a transistor and circuitry 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 wire connections and quality of the circuitry. Either module provides unlimited RPM. The conventional points and condenser/capacitor ignition system is less responsive.
  • Each module has two wire connections. One wire connects to the ignition coil and the other wire connects to the ground of the engine with use of a supplied installation screw. Scroll down for wiring diagrams and installation instructions Ê.

Universal Magneto Solid State Transistorized Electronic Ignition Module
Wiring Diagram and Installation Instructions Ê

These modules 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 ignition coils or multiple magnets under the flywheel with ignition coil under the flywheel, too.

Aftermarket Module with One Terminal and OEM Kohler Modules -

Secure the modules with the self-tapping screw to the engine sheet metal with good ventilation and air-flow and so each module is grounded. Fasten the brass lever of the Kohler module with its mounting screw so the lever will make contact with the center button on the module to kill the engine.

Disconnect or cut-off the points and condenser (ignition) wire from the coil (leave long). Connect this wire to the supplied long wire to the terminal of the aftermarket module and to the kill switch, or connect the ignition wire to the black wire on the Kohler module. Use the supplied wire nut to connect the two wires together. Replace the blower housing (if removed), crank the engine rapidly and check for spark at the spark plug's tip. If no spark, recheck the wiring for proper or correct connections.

Aftermarket Module with Two Terminals -

Use the supplied short wire with the female connector and ring connector to connect to the negative terminal of the module to engine ground with the supplied self-tapping screw. Secure the module with the self-tapping screw to the engine sheet metal with good ventilation and air-flow.

Disconnect or cut-off the points and condenser wire from the coil (leave long). Connect this wire to the supplied long wire to the positive terminal of module and to the kill switch. Use the supplied wire nut to connect the two wires together. Fasten the module to the sheet metal of the engine Replace the blower housing (if removed), crank the engine rapidly and check for spark at the spark plug's tip. If no spark, recheck the wiring for proper or correct connections.

Points Pushrod/Plunger Hole Plugs and Block-Off Plates. Use either of the items below to plug or block-off the points pushrod/plunger hole in Briggs & Stratton or Kohler engines when doing away with the points and condenser/capacitor, and converting engine for use with a Universal Solid State Ignition Module, crank trigger electronic ignition or from Kohler K-series ignition to Kohler Magnum solid state ignition. Use needle-nose pliers to hold the plug and a small hammer to tap it in the hole in the block. Fits very tight. For the block-off plate, use RTV silicone sealant to prevent oil leaking and OEM points mounting screws to secure in place. Cup plug no longer available from Kohler (25 139 51-S). NOTE: Instead of using any of these items, remove the points and points pushrod. Place the pushrod on a flat, hard surface, and use a sharp cold chisel and hammer to lightly create some knurled raised places on it. Then insert the pushrod in the block and it may need to driven in with the hammer. The knurled places will retain the pushrod in the block. An original, ingenious and innovative concept by Brian Miller, because nobody else advertise these for use on a Kohler engine.

Ignition Coils. NOTE: Most failures of battery ignition coils is caused by overcharging of the electrical system due to a defective voltage rectifier/regulator or defective [automotive] battery will 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 amp gauge to keep an eye on the charging system.

Use with points and two standard capacity condensers/capacitors or one high capacity/performance condenser/capacitor for full coil saturation and a strong spark so engine will idle smooth and accelerate quickly at full speed, or can be used with A-1 Miller's custom crank trigger ignition system. Set spark plug gap at .035" with this coil. This genuine Bosch blue coil is epoxy filled with a steel casing. All epoxy filled or molded epoxy coils will hold up to severe vibrations, can be mounted in any position and will not leak oil (because there is no oil). $55.00 each, plus shipping & handling.

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 ignition control module, or connect with coil having a minimum 1.4 ohm internal resistor to prevent burning up the Dynatek Dyna S or PerTronix Ignitor 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 "Points 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 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. 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 amp gauge to keep an eye on the charging system.

The only time they need replacing is when damaged beyond use. All spark plug wires can be checked with an analog or digital multimeter. Also, certain spark plug wires below Ê don't have the terminal and boot for the coil installed. Each spark plug wire needs to be safely routed from the spark plug to the coil, allow some length for flexibility, and may need to be cut off if excessively long. Then install the boot on the wire that fits your coil best, strip off about 1/2" of insulation, bend the wire over, install the terminal over the wire and on the insulation, then lightly crimp the terminal with pliers. The squeezing pressure of the terminal in the coil tower ensures the wire will stay in the receptacle.

Complete Battery-Powered Ignition Conversion/Upgrade 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 a longer 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/upgrade is 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.


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, etc., that originally came with a magneto ignition system (having 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. Kit includes: new standard-output/stock (20,000 volt) canister ignition coil with 3.0 ohm internal resistor and mounting bracket; battery-ignition condenser/capacitor; 22" length 16 gauge coil-to-points wire w/grommet and terminals; and 22" length suppression/carbon core spark plug wire. NOTE: Must use a universal automotive start/ignition key switch, or an ON/OFF toggle- or key-switch to power the ignition and a push-button switch to crank the engine. 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.

Convert from Breakerless Ignition to Battery-Powered Points and Condenser Ignition 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 points and condenser/capacitor ignition. Kit includes: new standard-output/stock (20,000 volt) canister ignition coil with 3.0 ohm internal resistor and mounting bracket; new ignition points; 22" length 16 gauge coil-to-points wire w/grommet and terminals; points pushrod; points cover; points cover gasket; four 10-24 UNC screws; battery-ignition condenser/capacitor; and 13" spark plug wire. Use the same 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 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 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. Set points 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.

100% Digital Maintenance-Free Crank Trigger Electronic Ignition Kits with Self-Contained Dynatek Dyna S or PerTronix Ignitor Sensor/Modules for Single- or Opposed Twin-Cylinder Engines - (Updated 3/30/17)

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 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 quickly to full speed (wide open throttle) 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 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 suppression/carbon core or metal core spark plug wire, and/or resistor-type or non-resistor/copper core spark plug can 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 or high-output/performance ignition coil, as long as the coil has a 3.0 ohm internal 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 resistor. A metal core spark plug wire can be used with either sensor/module. Being metal core spark plug wires do not suppress electro magnetic interference (EMI) which will interfere with electronics in the PerTronix Ignitor, if engine runs erratic or misfires, then a suppression/carbon core spark plug wire should be used instead.

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 an engine accelerate at the speed of electricity, which can be anywhere from about 50% to 99% of the speed of light, depending upon the wire and insulation composition and construction.

Spark occurs when a small and super strong neodymium/rare earth magnet embedded in an aluminum locking ring, which is much like an automotive reluctor ring, that's fastened on the crankshaft's PTO end pass the sensor/module. (Neodymium and rare earth 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 -

Unlike the competitor's, 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 magnet ring. 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 magnet ring is .010"-.060". Sensor/module may not operate or engine may misfire if gap is wider than .060". Dielectric grease is not needed between the sensor/module and mounting plate. NOTE: Do not allow sensor/module to make contact with locking magnet ring while engine is running!

NOTE: The Dynatek Dyna S and PerTronix Ignitor maintenance-free crank trigger electronic ignition kits just below Ê installs and operate off the PTO end of the engine block, and is intended for competition pulling only. For crank trigger ignition kits that installs and operate off the flywheel end of the engine (mainly for general lawn and garden work), click HERE.

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 magnet ring (loose) on the crankshaft back and forth by hand. Each time the embedded detector/trigger magnet passes 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 -

  1. 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.
  2. With the locking magnet ring loose on the crankshaft, rotate the ring by hand to align the magnet with the center of the sensor/module.
  3. 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 or PerTronix Ignitor sensor/modules - (This is also how to test if the sensor/module is functioning or not.)

  1. 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.
  2. Connect a battery-powered test light or multimeter [set on the 12 volt reading] between the negative (–) coil terminal and chassis/engine ground.
    • For the Dyna S module, the light should be off or the multimeter should show no voltage reading. It is at this point when spark occurs.
    • For the Ignitor module, the light should illuminate or the multimeter should show approximate battery voltage reading. It is at this point when spark occurs.
  3. 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.
  4. With the Allen set screw loose in the locking magnet ring, rotate the ring until the magnet is centered with the sensor in the module. Again...
    • For the Dyna S module, the light should be off or the multimeter should show no voltage reading.
    • For the Ignitor module, the light should illuminate or the multimeter should show approximate battery voltage reading.
  5. Tighten the Allen set screw in the ring on the crankshaft. The ignition timing is now set close to where it needs to be.

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 magnet ring while engine is running! -

  1. 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.
  2. If the timing is not set correctly, shut off the engine and loosen the Allen set screw in the locking magnet ring, slightly rotate crankshaft by hand one way or the other to advance or retard the timing, and position the ring with the magnet centered with the sensor in the module, and tighten the Allen set screw.
  3. 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.
  4. 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.
  5. No further adjustments are required.


Maintenance-Free Crank Trigger Electronic Ignition Setups That Operates Off the Flywheel End of the Engine (Updated 6/9/17)

Get That Old Engine Running Again With 21st Century Technology Using 100% Digital Crank Trigger Electronic Ignition, 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, crank trigger electronic 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, crank trigger electronic ignition is the way to go! It will allow the engine to idle smoothly and accelerate quickly to full speed (wide open throttle) with no hesitation or misfire.

Tired of changing or constantly adjusting the ignition points? Convert to the 100% digitized crank 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 for Breakerless Ignition), but does have a 3/4" wide area between the fins and ring gear (as shown in the pictures above and to the right), or a billet steel flywheel, to use a magnetic pickup coil, inductive proximity sensor, a small, short hardened steel Phillips or button head socket head (Allen) screw 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 crank trigger electronic ignition. The curvature or dome shaped heads of button- and Phillips-head screws makes them ideal for use on a trigger disc or flywheel. Install the screw head extended a minimum of 1/4" above the surface of the flywheel to prevent any out of time spark occurrences by the flywheel itself. Or if using a non-magnetic pickup coil, hall effect proximity sensor or a PerTronix Ignitor non-magnetic sensor/module, a small ring magnet fastened by a small [hardened] screw can be used to create a rotating magnet detection target. The head of the retaining screw will become magnetized. An 8-32 UNF and 10-32 UNF 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 trigger screw, pin or small magnet installed, it can be dynamically precision spin-balanced, or weighed on a precision scale, and the exact weight of the installed trigger screw or magnet w/screw can be ground away or drilled out on the opposite side of the flywheel to put it back in balance. 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. And for the ignition timing to be set at 20º BTDC, with the S and raised boss (timing marks) on the bearing plate aligned, the screw will need to be located at 2-3/8" when using a magnetic pickup coil, and 3-1/2" to 4" when using a 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) on the flywheel, then there's no need to modify the flywheel for this conversion or upgrade. Although new 10-24 UNC threads will need to be cut in the two raised bosses in the bearing plate to mount the bracket for the sensor if they're not already present.

Magnetic pickup coils and proximity sensors are very sensitive to mechanical damage (and electrical damage if connected wrong). For magnetic pickup coils and inductive proximity sensors set the air gap/clearance from the detection/trigger target (screw, pin or small raised area on the rotating disc) at .010"-.060" with a brass, plastic, poster board, stainless steel (anything non-magnetic) feeler gauge. 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.

Some proximity sensors have an LED (Light Emitting Diode) on the rear of unit. If the proximity sensor is wired incorrectly, the LED will stay on and go off when activated. Being 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. Click here for wiring diagrams.

High Quality Digital Tachometer/Proximity Sensor Kits. Will work with small engines or automotive engines, gas or diesel. This precision digital tachometer is triggered by the same method as crank trigger ignition with a proximity sensor to detect a target, which can be a small ferrous steel screw or pin, or magnet in a rotating disc or on flywheel. A sturdy steel or aluminum bracket will need to be fabricated by customer to mount the sensor in close proximity of the detector/trigger target. Set air gap/clearance at .010"-.188". Tachometer can be dash- or panel-mounted. Tachometer works with 8-24 volts DC, proximity sensors works with 6-36 volts DC. Displays up to 9,999 RPM. Very accurate. Tachometer returns to zero [0000] when power is turned off. Wiring Instructions: #1 wire on tachometer connects to brown wire on (either) proximity sensor and ignition switch (battery positive (+) post), #2 wire on tachometer connects to blue wire on (either) proximity sensor and engine/chassis ground (battery negative (–) post), and #5 wire on tachometer connects to black wire on (either) proximity sensor. Wires #3 and #4 connects to nothing. Wiring can also be integrated with crank trigger ignition with a proximity sensor. Choice of RED or BLUE numeric display.

IMPORTANT! Most quality-made starter motors are designed to last the life of an engine. Therefore, if a good starter burns up prematurely, then this means that it has cranked an engine for too long at one time. All starters, including automotive starters, are actually 6 volt motors operating on 12 volts. This is what gives them so much torque to crank an 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 windings. The longer it's spun, the stronger it will get, which causes the wire 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 it 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!)

Universal 15 and 20 Amp Gauges / Ammeter Kits. Install one of these gauges to know exactly what the charging system on your engine is doing. Having an 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 (+) with no gradual "falling back" to zero on the gauge (if installed), this will send too much voltage to the battery, which could eventually burn up the cells, or the ignition coil, which could eventually burn up the primary windings. Overcharging of the electrical system could also burn up the electronic ignition control module (crank trigger), burn out light bulbs, electric PTO clutch and any other electrical accessories. Gauges registers up to 15 or 20 amps of charge, depending on total output amperage of stator or alternator. As battery becomes fully charged, needle slowly moves from positive side (+) to zero (0). If no charge goes to the battery, needle will stay on negative side (–). 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 gauge. Requires 2" diameter mounting hole and comes with mounting clamp and nuts. 30 amp gauge kit discontinued from Kohler. Replaces Kohler part # 48 755 18-S.

Each have same mounting holes and fit many 8 thru 24hp Kohler engines with a 15 amp output alternator charging stator under the flywheel. Can be used on most Harley-Davidson motorcycles, too. Terminals: "Two over (AC - AC), one under (BAT+)." NOTE: 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.

New Ring Sets, and Piston and Ring Set - Please contact me if you're interested in any of these parts or services. | Top of page

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 and 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.
IMPORTANT! 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 - If a STD size or .010" undersize rod is in good condition, the matching crank journal can be reground so it's perfectly round again and then if the original rod isn't badly scored or burnt, it can be resized to fit to odd-size undersize journal. IMPORTANT: To prevent scoring of the rod when the engine is started for the first time, apply automotive wheel bearing grease or chassis lube 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.

ALCOA connecting rods for Kohler K-series engine model K361. Also fits the K301/M12, K321/M14 and K341/M16 engines. Extremely strong rods. These rods have a narrow wrist pin hole for the Mahle (Magnum), K341 and K361 pistons. Comes with long dipper. 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: 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 - If a STD size or .010" undersize rod is in good condition, the matching crank journal can be reground so it's perfectly round again and then if the original rod isn't badly scored or burnt, it can be resized to fit to odd-size undersize journal. Bearing inserts cannot be used. IMPORTANT: To prevent scoring of the rod when the engine is started for the first time, apply automotive 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.

Connecting rods for Kohler engine models K482, K532, K582 and K660/K662 are no longer available from Kohler. I don't stock these rods. 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 K532 or K582 connecting rods can be bored for installation of matching replaceable bearing inserts. Certain bearing inserts for British MG car engines will fit the K532 and K582 rods perfectly when the rod is bored to accept the (STD size, .010", .020" or .030" undersize) bearings. The alternative to using undersize 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 badly scored or burnt, it can be resized (in a connecting rod honing machine) to fit or match the odd-size undersize journal. Bearing inserts cannot be used in this procedure. Contact Elson Nichols of Loop 70 Auto Parts and Automotive Machine Shop, 14 Bus. Loop 70 East, Columbia, Missouri 65203 USA. Phone: 1-573-449-0893.

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.

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 stock head and stock head gasket) or offset .060" (5.360" rod length; use with a non-milled OEM head and stock head gasket) to pop the piston out of the cylinder (see below Ê) to raise the compression and help improve air flow 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 proper 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".

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 proper valve clearance.

NOTE: In an OHV engine with worn or dry-rotted valve stem seals, when the engine is shut down and allowed to sit for a period of time, oil seeps down past the opening in the seal in the combustion chamber. As a result, as soon as the engine is started, the oil is burned, and no more smoke until the engine is shut down, and the process repeats itself. Also, the seeping oil will cause an excess of carbon deposits to build up under the valve head(s), preventing a full flow of air to enter (or exit) the combustion chamber, causing the engine to lose power at high RPM.

Exact 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 no longer available from Kohler.

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 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 18hp OHV cam, and approximately 11% more than the flathead engine cams at 4,000 RPM. This cam sounds just like an OEM 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. 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. Tested and proven design over the competitor's. 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 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!

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 2, KT19 series 2, M18 and M20 for competition pulling only with stamped steel valve retainers below. These springs are more aggressive than OEM Kohler valve springs. 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 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 stamped steel/non-rotator retainers and keepers/locks/collets. Do not use with OEM valve rotators! 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.

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 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 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 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 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. To be used with wide 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.

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 valve springs above È. Designed 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 stamped steel/non-rotator retainers and keepers/locks/collets. Do not use with OEM valve rotators! 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. 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 tool. Same diameter as OEM Kohler springs. Dimensions: .697" i.d.; .953" o.d.; 2" uncompressed height. Specifications: Seat load: 55 @ 1.500"; Open load: 127 @ 1.000"; Coil bind: .950"; Spring rate (lbs/inch): 144. Made by Comp Cams.

NOTE: The 7" length camshaft pin is no longer available 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 cup-type expansion 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 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, it makes for a clean and professional-looking repair job. It can't be easily seen or noticed between the parts.

Single Cylinder Head Stud Kits for Kohler engine models K241/M10, K301/M12, K321/M14, K341/M16 and K361 with an OEM 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 stud, apply medium strength liquid threadlocker (Red Loctite, Permatex or equivalent) on threads that goes in block to prevent stud from loosening. Apply motor oil on stud 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 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. Please accept no other advertised copycat products of this kind.

Reconditioned OEM Kohler Crankshafts - (When available.)

Available for Kohler engine models K241/M10, K301/M12, K321/M14, K341/M16 and K361. These cast iron cranks are genuine OEM Kohler, Used and in excellent condition. They have either a 1" or 1-1/8" diameter x 3-1/2" length PTO shaft w/1/4" wide keyway. They have good gear teeth and may have a worn or unworn connecting rod journal in either STD size or undersize. Which can be reground to .010", .020" or .030" undersize. Although .030" is rare, it's still very safe to use. FYI - To be honest, these are old, used crankshafts. So if you need one with an unworn STD size rod journal, you'll probably have a better chance of winning the lottery than finding a used Kohler K-series or Magnum single cylinder crankshaft with an unworn STD size journal. And if you're going to use a pulley, clutch, etc., on the PTO end, then I will need to know the exact dimensions of the PTO end on your crankshaft so I can match it to one that I may have in stock. 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. For accuracy, measure the length from the oil seal shoulder out. If you have the engine's original model and specification numbers, you can find the correct part number, dimensions and specifications of the crankshaft here: CRANKSHAFT REFERENCE MANUAL.

To avoid cracking oil pan, do not over-tighten! If in doubt, to insure proper sealing and to prevent a possible oil leak, use plumber's tape on the threads. Universal application. Magnet attracts and removes ferrous metallic (wear) fragments from the motor oil to reduce engine wear. 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).


Powerful Rare Earth/Neodymium Magnet for Engines 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 to gears and bearings. Install magnet to inside bottom of oil pan away from the oil dipper and moving parts, or to inside bottom of a gear case or gear housing away from any rotating gears and moving parts. Engine or gears/bearings will last longer due to cleaner oil. Use Krazy Glue, Super Glue, Gorilla Glue, or any industrial strength adhesive to secure magnet in place. This rare earth/neodymium magnet is EXTREMELY strong! Use caution when handling! Can be difficult to remove from a steel or cast iron surface, is 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.

Bolt-On Header Pipe Flange/Stub Tube Adapters. Hub has beveled edges for smooth, uninterrupted exhaust flow. Designed for use on Cub Cadet and other makes and models of garden tractors with Kohler engine inline with tractor. No mounting gasket required. Use clear RTV Silicone Adhesive Sealant instead of a gasket because exhaust heat has no effect on silicone, it allows the two metals to have full contact so mounting bolts will not loosen. Of course, having the end of exhaust port on the block resurfaced (with a grinding stone in a milling machine) will help, too. Plus, clear silicone makes for a professional-looking job because it can't be easily seen or noticed. The flange/hub is also small enough to clear the governor lever. NOTE: If your block don't have two 5/6-18 UNC bolt holes on the end of exhaust port, they will need to be drilled and tapped at precise locations to match holes in flange. There is no other way to fasten flange to the block.

Kohler model K361 Cylinder Head Repairs - 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 valve seats from the head. Contact Elson Nichols at 573-449-0983 for more details of the bronze valve seats. Click here for cylinder head bolt torque specs.

  • $75.00 each, plus shipping and handling.

NOTE: Before lapping in valves, it's best to have the valve seats reground or recut so the angle will be in correct alignment with the centerline of the valve guides and so the valve face will make a full 360º contact with the seat, or the valves will leak and the engine will lose compression, be hard to start, be low on power and possibly make a popping sound through the carburetor or out the exhaust. And be sure to set the clearances correctly, too.

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: $60.00 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. 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: 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 .

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 CB278P/CB279P or Sealed Power 9885CP/9885CPA bearing inserts will be installed. All A-1 Miller machined connecting rods include notches to prevent bearing rotation in rod. No cheap Chinese-made bearing inserts ever installed. Please indicate diameter of crank journal for size of bearing inserts. (STD size, .010", .020" or .030" 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.
  • Clevite 77 or Federal Mogul Bearing Inserts. Available in STD size, .010", .020" and .030" undersize. $17.00 each, plus shipping and handling.
  • Bore your rod only (customer supplies and installs own bearing inserts): $25.00 labor, plus return shipping and handling.
  • Bore your rod and install our bearing inserts: $42.00 ($17.00 for bearing inserts + $25.00 labor to bore rod), plus return shipping and handling.
  • Purchase one of our rods, bore rod and install our bearing inserts: Price of rod $? + $17.00 for bearing inserts + $25.00 labor to bore rod = $? total (see list of available rods and prices further down in this website Ê), plus return shipping and 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 stock head) or offset .060" (5.360" rod length; use with a non-milled OEM head) to pop the piston out of the cylinder (see below Ê) to raise the compression and help improve air flow 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 proper 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 16hp K-series cast piston or "new style" Mahle (Magnum) forged pistons. $20.00 labor, plus return shipping and handling.

Please contact me if you're interested in any of the above È parts or services.


Bare Kohler K-series Engine Blocks (when available) - Top of page NOTE: The old Kohler cast iron engine blocks are hard to find nowadays. I've been to some small engine shops around Missouri where they would throw these old blocks out back in a scrap metal pile. They're good blocks, too! The shop just didn't want to rebuild them because they're factory-trained to repair newer aluminum block engines, or replace the old engine with a new one. Some of the cast iron Kohler blocks listed below Ê may have light rust from sitting out in the weather before I found them. I wire-wheel the rust off the best I can. I just want to let you know this so you won't think I sell junk.
  • K141 (6.25hp) and K160 (6.6hp) bare blocks with 2-7/8" bore. $40.00 each, plus shipping and handling.
  • K161 (7hp) and K181/M8 (8hp) bare blocks with 2-15/16" bore. $40.00 each, plus shipping and handling.
  • K241/M10 bare block. $65.00 each, plus shipping and handling.
  • K241 bare block with 10hp bore and K301 embossed on the PTO end (extra thick cylinder wall). $200.00 each, plus shipping and handling.
  • K301/M12 (12hp) bare block. $125.00 each, plus shipping and handling.
  • K321/M14 (14hp) bare block. $175.00 each, plus shipping and handling.
  • K341/M16 (16hp) 12 fin bare block. $250.00 each, plus shipping and handling.
  • K341 (16hp ) 13 fin bare block. $400.00 each, plus shipping and handling.
  • Packaged shipping weight for each block: 45 lbs.

Unlike the small block Chevy V8's, the Kohler K-series and Magnum engine block models K241/M10, K301/M12, K321/M14 and K341/M16 are not all the same. There are many variations in bolt patterns and PTO flange configurations between these blocks. Before replacing an engine block and if possible, the best thing to do is have the original engine rebuilt, then all the original accessories will attach to the original block with no modifications. But if the original engine block is not rebuildable and damaged beyond repair, another block of the same type (specification number) will need to be acquired. If interested in purchasing a bare block, please email me several detailed, sharp pictures of your original engine block taken at all sides so I match it to one I may have in stock.

The Major Differences Between the K241/M10 (10hp), K301/M12 (12hp), K321/M14 (14hp) and K341/M16 (16hp) Kohler Engine and Blocks -

  • The K241/M10 blocks have a STD cylinder bore of 3.250" and the stroke is 2.875". All of these blocks have an exhaust valve diameter of 1.125" and the intake is 1.375". Some rare K241 blocks have "K301" embossed on the PTO end. These have a thicker cylinder wall than ordinary K241 blocks.
  • The K301/M12 blocks have a STD cylinder bore of 3.375" and the stroke is 3.250". There are no other major differences between these two blocks. These blocks have the same size valves, and most external parts will interchange. Due to the smaller cubic inch displacement, which lessens the amount of air that enters the engine, theses engines use a Carter or Kohler #26, or Walbro #52 (1.07" throttle bore) carburetor.
  • The K321/M14 blocks have a STD cylinder bore of 3.500' and the stroke is 3.250". There are no other major differences between the K241/M10, K301/M12 or K321/M14 engines. The early K321 blocks have an exhaust valve diameter of 1.125", and the valves in the later K321 blocks are the same diameter, which is 1.375". Some internal, but most external parts on the K241/M10, K301/M12 and K321/M14 engines will interchange, with the exception of the early style K241 cylinder head and size of the carburetor. Due to the larger cubic inch displacement, which increases the amount of air that enters the engine, the K321/M14 engines use either a larger Carter or Kohler #28 or #30, or Walbro #60 (1.17" or 1.2" throttle bore) carburetor.
  • The K341/M16 blocks have a STD cylinder bore of 3.750" and the stroke is 3.250". There are no other major differences between the K241/M10, K301/M12 or K321/M14 and K341/M16 engines, except the valves are the same diameter, 1.375" and the K341/M16 blocks have 10 cylinder head bolts. Due to the larger cubic inch displacement, which increases the amount of air that enters the engine, the K341/M16 engines also use a #30 (1.2" throttle bore) carburetor. And most external parts, except the cylinder head and air shields, will interchange with the K241/M10, K301/M12 or K321/M14 and K341/M16 engines.
  • Some blocks have wide base flanges (for the wide, deep oil pan) and some have a narrow base with no flanges (Cub Cadet, John Deere, Wheel Horse or Ford).
  • Most Magnum blocks are wide base, and very few are narrow base.
  • The very early K241 10hp blocks have no indentation for installing an upper mount gear starter (mounting bolts are below the starter motor). Also, some of these older blocks with flanges have no holes drilled for converting to a narrow base oil pan. (But holes can be drilled and tapped.)
  • Some blocks have either a drilled or threaded oil dipstick tube hole next to the cylinder, above the crankcase, while others have no hole present.
  • Some blocks have provisions for a starter-side oil dipstick tube, and some don't.
  • Some blocks came with counterbalance gears and some didn't. Some have expansion plugs where balance gear stub shafts can be installed, and although certain blocks have the bosses, some have no holes drilled for the stub shafts.
  • The later model Kohler blocks with Breakerless Ignition and all Kohler Magnum blocks have no provisions for ignition points.
  • Some blocks have two threaded holes for installing an exhaust pipe flange, and some don't.
  • Some blocks have provisions to install a mechanical fuel pump, and some don't.
  • Some blocks have different bolt patterns on the PTO end, and Gravely blocks have a raised circular flange. (See below Ê.)
  • Some K241 blocks with K301 embossed on the PTO end have a thicker cylinder wall, and some K241 blocks without the K301 embossing have an ordinary thickness cylinder wall.
  • The 12 fin K341 blocks have an ordinary thickness cylinder wall, and the 13 fin K341 blocks have a thicker cylinder wall.
  • Other than all of the above È, everything else on the Kohler K-series engine blocks are pretty much the same.

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, atmospheric/barometric pressure and air temperature where the engine will be used, the customer will need to make the final adjustments so the engine will run smooth. No carburetor with an adjustable high speed air/fuel adjuster comes preset, not even new ones.

Regarding an Engine Build Estimate -

I am very meticulous in how I rebuild and build engines. If you wish 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'll build your engine to the maximum horsepower/torque in accordance with your club's rules, not less than what the rules permit. I also rebuild ordinary 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 wish 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 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.
  • 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 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!

Stock, Hot-Stock or Stock-Altered Class 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; 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, a very strong rare earth/neodymium magnet will be attached in the bottom of the oil pan to attract and remove ferrous metallic (wear) fragments from the motor oil to clean the oil so the engine will last much longer. An innovative and ingenious concept by Brian Miller because nobody else advertise this trick online for a pulling engine.

And I don't paint my customer's purchased engines for two reasons: 1) They may not like the color itself or the shade of the color, and 2) Paint covers the work that was done to the engine. I want my customers to see what they are paying for.

When you receive the engine, paint it, 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. Add A-1 Miller's custom crank trigger electronic ignition system for $95.00 - $152.00, depending on type of setup.

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 A-1 Miller's custom crank trigger ignition system for $95.00 - $152.00 extra, depending on type of setup. (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.

IMPORTANT!

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

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. Then drain the oil while it's hot, and 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. 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.

NOTES:

IMPORTANT! 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! I 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 mishandle and 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 hard on 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. 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 always make the long drive to A-1 Miller's shop to personally drop off and/or pick up your engine, transaxle, tractor, etc.

If shipping an engine, use 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 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 on the bottom so a forklift can move it without damage. Make the crate compact as possible to save on shipping charges and for it to be easier to handle. 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 and handling. For payment, I accept cash (in person), USPS Postal Money Orders, cashier's checks, MasterCard, VISA, Discover, American Express and Western Union Money Transfer. (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.

IMPORTANT! When bringing or sending your engine, transaxle or any other part(s) to us, please include a note with your name, address, phone number and a description of what you want done.

Clutch Parts, Driveshafts, Clutch Rebuilding Services and Machine Shop Services

Updated 2/19/16 | Top of page


Single & Double Clutch Assemblies for an IH Cub CadetClutch Parts and Rebuilds. For competition pulling, heavy towing, pushing snow or lawn and garden use. It's possibly the last clutch your tractor will need! I also rebuild plain stock OEM Cub Cadet garden tractors clutch assemblies and the IH Cub Cadet "Original" (belt drive) clutch assemblies! And I sell our clutch parts individually for the do-it-yourself rebuild. Also, I don't sell complete clutch assemblies because I don't have enough parts to put them together. But I can rebuild your clutch assembly, if you don't mind sending it to me. I can rebuild your clutch assembly however you want. Just tell me how you're going to use your tractor and we'll build your clutch to suit your needs.


Driveshafts for IH and MTD-built Cub Cadet models 70, 71, 72, 73, 86, 100, 102, 104, 106, 108, 122, 124, 126, 128, 580, 582, 800, 1000, 1050, 1200, 1250, 1450, 1650 (with a hydrostatic disconnect attachment) 1604, 1606 and 1806. Spiral pins sold separately. (Scroll down). NOTE: These driveshafts are made to order. When ordering, please specify model of Cub Cadet and possibly exact length and exactly where the spiral/roll pin holes needs to be drilled. Please indicate if the 3rd hole should be drilled or a split clamping collar will be used instead. For competition pulling, it is recommended that a split clamping collar be used. To determine the exact length, 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 Cadet are also available. Ê

Please contact me if you're interested in any of the above È parts or services.


Driveshafts for Cub Cadet "Original" and Hydrostatic Drive Cub Cadet -

Driveshaft for IH Cub Cadet "Original" and models 105, 107, 109, 123, 125, 127, 129, 147, 149 and 169. Available in 1144 Stress Proof steel only. Spiral pins sold separately. (Scroll down). Please specify with or without creeper drive.


Driveshaft for Cub Cadet models 1100, 1250, 1450 and 1650. Replaces Cub Cadet part # IH 140079 C1. Spiral pins sold separately. (Scroll down).


Driveshaft for MTD-built Cub Cadet models 680, 682, 782, 782D, 784, 882, 982, 1210, 1211, 1282, 1512, 1541, 1710, 1711, 1712, 1810, 1811, 1812 and 1860. 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.

Please contact me if you're interested in any of the above È parts or services.


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.

For Cub Cadet "Original" garden tractors -

For all other models of Cub Cadet garden tractors -

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 and handling.


Clutch Drive Studs w/Nuts for MTD-built Cub Cadet 3-pin clutch drive plate or convert the OEM Cub Cadet 3-pin clutch drive plate into a 6 pin/stud clutch driver.

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.


Fiber Material Clutch Discs for IH- and MTD-built Cub Cadet garden tractors. Can be used with a 3- or 6-pin drive plate.

IMPORTANT - Both pressure plates MUST be resurfaced to remove warpage and until perfectly flat and trued-up (to reduce vibration) in a metal lathe or severe clutch slippage may result!

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

Please contact me if you're interested in any of these parts or services.


New machined aluminum clutch disc with (6) 13/32" drive holes for a 3- or 6-pin drive plate. This is a direct replacement for Cub Cadet's OEM fiber clutch disc. Made of the highest quality 6061 alloy; medium-grade hardness aluminum available. The circumference of disc 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 in my milling machine. Unlike the competition that offer the same copycat part, the drive holes in my aluminum clutch discs are drilled to 13/32" for less clutch disc noise/rattle and less chance of breakage to the drive pins/studs. An original, ingenious and innovative concept by Brian Miller, because nobody else originally advertised this part online. IMPORTANT - Both pressure plates MUST be resurfaced to remove warpage and until perfectly flat and trued-up (to reduce vibration) in a metal lathe or severe clutch slippage may result!


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 pulling tractors due to harmonic vibration, creating the possibility of the spring(s) becoming dislodged, which could become a hazardous airborne projectile if clutch is not properly shielded 360º. OEM Cub Cadet part # 932-3018.

Repair Services.

  • Professionally resurface YOUR Cub Cadet pressure plates until perfectly flat with a smooth, slick surface, and then true-up outer edge to prevent run-out (wobble/out-of-balance). Minimal metal removed to maintain maximum thickness and diameter. OEM Cub Cadet steel pressure plates are stamped in a large press and not machined in a lathe at the factory, which makes them oblong (egg-shaped) and not perfectly flat. Oblong (being out of balance) pressure plates will cause the bronze pilot bushing to wear and the driveshaft to break at high RPM or wide open throttle. And pressure plates that's not perfectly flat will cause the clutch to slip or wear unevenly. $15.00 labor for two pressure plates, plus return shipping and handling.
  • Rebuild Your Pressure Plates. Reuse your center hub, replace deep-pitted rusted, severely worn or bent pressure plate with a new mild steel plate, resurface plate until perfectly flat with a smooth, slick surface, and then true-up outer edge to prevent run-out (wobble/out-of-balance). $25.00 each for parts and labor, plus return shipping and handling.

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 grease is all the clutch release/throw-out bearing and driveshaft receives for the life of the clutch 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. Heavy wall tubing measures .626" i.d. x 1" o.d. x 1/2"± length. Third spiral pin hole or split clamping collar(s) behind pressure spring may need to be relocated 1/2" further back on driveshaft. Lubricate with an automotive grease gun once a year. An ingenious and innovative concept 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 (.050"± thickness) goes between rear pressure plate and teasing spring. Thrust washer prevents teasing spring from "catching" in the slot of the rear pressure plate upon clutch engagement and possibly breaking. This twists the spring a few thousandths of an inch, which could cause it to eventually break, even with the cup/spacer below. (Another factory flaw that happens several years later.) An original, ingenious 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.

  • Teasing Spring and Thrust Washer Kit. $6.00 per kit, plus shipping & handling.
  • Teasing spring alone. OEM Cub Cadet part # 932-3017. $5.00 each, plus shipping & handling.

Also fits Cub Cadet models 1250, 1450 and 1650 equipped with a hydrostatic disconnect attachment. IMPORTANT: When installing this part on driveshaft, the wide/flared end faces forward and the narrow end goes against the throw-out bearing.
  • OEM Cub Cadet part # 911-3040. $16.15 each, plus shipping & handling.
5/8" i.d. Split Clamping 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 bearing block bearing installed), and when used with a bearing block bearing mounted on angled steel (that's welded to inside tractor frame), it prevents driveshaft wobble and possible breakage at higher RPMs or 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 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 collars or a pillow block bearing with an eccentric locking collar because just one split clamping collar might slip on the "slick" and hardened surface of stainless steel.

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. Please accept no other advertised copycat products of this kind. Return To Previous Paragraph

Also custom-length rigid tubular driveshaft couplers, up to 6" in length are available. 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.

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.

Because if it's dry, chances are, the driveshaft won't release, it can bind up and wear both the bushing and driveshaft.


The IH Cub Cadet "Original" Clutch Assembly - | Please contact me if you're interested in any of these parts or services.

An engine that runs at high RPM or wide open throttle, the bronze bushing in the IH Cub Cadet "Original" clutch disc/pulley will not last long under side-thrust. Therefore, it'll be a good idea to have a sealed, high speed radial ball bearing installed in the clutch/pulley disc. See the picture below Ê for a better understanding.


The drive belt for an IH Cub Cadet "Original" is part number IH-376230-R1, the size is 3/8" wide x 31-1/2" length and it retails for about $12.00 (as of 3/21/12).

Professionally Constructed Pulling Hitch Assemblies for Garden Pulling Tractors and 1,500 lb. Small Wheel Mini Rods. This is the design that's preferred by professional pullers everywhere!

Specifications include:

  • The upper and lower brackets have two mounting holes each and fastens directly over the rear cover plate that's on the Cub Cadet transaxle using the two upper and the two outer lower existing bolt holes. Slightly longer bolts will be required. Requires four grade 8 bolts or hardened steel studs w/hardened nuts (not included with hitch). This hitch could be adapted to the rear of the frame of another type of garden tractor, too. If your tractor have a heavy flat plate of steel on the rear, my hitch can be fastened onto that. Otherwise, a steel plate will have to be installed. The hitch fastens directly to an IH-built Cub Cadet garden tractor transaxle housing. Center of hole in the drawbar is located about 6" from the center of the rear axle.
  • Drawbar is held stationary by two threaded rods with four large jam nuts. The two holes are drilled at 25/32" for easier adjustment of the drawbar height.
  • Assembly weighs approximately 6-1/2 lbs.
  • All bare metal, except the threaded rods and nuts, are coated with gray primer.
  • Each hitch/drawbar below Ê are constructed to hold up to severe strain and punishment. In other words, they're built tougher than they should be.
  • Do-It-Yourself Garden Tractor Pulling Hitch with Brackets and Drawbar Only. Customer supplies own adjustable nuts and welds-in 3/4" threaded rods. $40.00 each, plus shipping & handling.
  • Complete Bolt-On Garden Tractor Hitch with Brackets, Drawbar, Threaded Rods and Nuts. Threaded rods welded to upper bracket. $45.00 each, plus shipping & handling.
  • Complete Mini-Rod Hitch. Includes: 8" wide, 1/4" thick upper and lower steel angle brackets, 7/8" diameter threaded rods with 4 adjustment hex nuts, 3/4" thick x 3" depth x 8" wide steel drawbar with a 1-1/2" hole for hook bored centered in drawbar. $65.00 each, plus shipping & handling.
Drawbar only for build-it-yourself garden pulling tractor hitch. Comes with a 1-1/2" hole for hook. Edge of 1-1/2" hole is spaced 3/4" from rear of drawbar for maximum strength and safety. No holes for adjustment rods. Customer locates and drills own holes. Dimensions: 6" wide x 2-1/2" depth x 1/2" thickness. Made of mild steel. An original concept by Brian Miller. Please accept no other advertised copycat products of this kind!

  • Has a 1/2-20 UNF left hand thread hole and 1/2-20 UNF right hand thread stud. $10.00 each, plus shipping & handling.


Heavy duty ball joint ends (Heim joints). Aircraft quality; extremely strong! Can be used on most garden tractors, go-karts, mini-rods, custom automotive transmission shifter linkage ends, etc. NOTE: Ball joint ends are required in aircraft and heavy duty machinery because they're much stronger than ordinary tie rod ends. They're a direct replacement for tie rod ends on most lawn and garden equipment and all that's needed is a 3/8" minimum grade 5 bolt to secure it to the steering lever. And these do not come with a dust/dirt shield, so they'll wear more when used for general lawn and garden use if not protected with a rubber seal. And when used with the seals below Ê, apply automotive grease to the ball in the Heim joints to help them operate smooth and last longer.

  • Has a 3/8-24 UNF right hand thread hole and 3/8" mounting hole. Our part # 170-166. $11.00 each, plus shipping & handling.
  • Has a 3/8-24 UNF left hand thread hole and 3/8" mounting hole. Our part # 116-844. $11.00 each, plus shipping & handling.

Rubber fits very tight against Heim joint to prevent dust, dirt, debris and moisture from entering spherical ball. Extends the life of Heim joints. These fit on both sides (top and bottom) of the spherical ball.

  • $12.00 per pair, plus shipping & handling.

NOTE: During the first part of the year, certain parts are back-ordered through some of our parts suppliers because a lot of other businesses are placing their orders for early Spring stock, too.

NOTE: True Gear stocks a lot of gears, but late Winter through early Spring is the rush time when they fill most dealers' orders. Customers' orders may be delayed due to this fact. | Please contact me if you're interested in any of these parts.

Custom Two Upper Cluster Slider Gears and Two Lower Stationary Gears for IH/MTD Cub Cadet transaxles. Precision CNC-ground, heat-treated and hardened gears. Smooth engagement with no rattle or gear teeth clatter. Gear sets includes one upper cluster gears and two lower gears. Intended for competition pulling, but can be used for general lawn and garden work to speed up or slow down tractor. Made by True Gear and Spline.

NOTE: Tooth count on upper cluster gear and matching bottom gear must add up to 52. Listed are the most popular sets:

1st and reverse gears (The 1st and reverse gears can have all the tooth counts for what ratio you would like; 13 teeth over 14 teeth up to 29 teeth), 14/15, 14/16, 15/16, 15/17, 16/17, 16/18, 17/18, 17/19, 18/19, 18/20, 19/20, 19/21, 20/21, 20/22, 21/22, 21/23, 22/23, 22/24, 23/24, 23/25, 24/25, 24/26, 25/26, 25/27, 26/27. Other gear sets are also available; from 13 teeth to 28 teeth in any combination you desire, as long as the gear teeth on both matching upper and lower gears add up to 52. Exception: for the upper 13 tooth cluster gear, reuse the OEM Cub Cadet 39 tooth lower (1st speed) gear. Use this Cub Cadet Gear Ratio Chart to determine which gears your tractor needs. (Open with Microsoft Excel or OpenOffice Calc and use Google Chrome web browser for a faster download of websites with large files.)

  • Above È gears, any combination. $120.00 per set, plus shipping and handling.

Custom Gears Installation Information: On the custom 2nd and 3rd gear set, the bottom gears are wider than the Cub Cadet OEM bottom gears. Therefore, the cone-shaped spacer at the front of the lower pinion shaft will need to be narrowed about .050" so the pinion gear will mesh correctly with the ring gear. Exception: for the 13 tooth cluster gear, reuse the OEM Cub Cadet 39 tooth bottom gear. And if the upper gears are larger in diameter than the OEM gears, the shifter fork may need grinding for clearance. Or if the gears are really big, a billet shifter fork will need to be installed. Otherwise, 1st and reverse gears and everything else should remain the same in the transaxle.

Install custom upper and lower transmission gears in your IH Cub Cadet transaxle, or complete IH Cub Cadet transaxle repairs, gear changes and modifications. A powerful magnet will also be placed in the bottom of the transaxle case to attract any wear fragments so gears and bearings will last longer.
