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 web site. 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 web sites. 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 web sites, 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 & handling. Because as of now, my web sites 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 web sites. 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

I have a mail-order garden pulling tractor parts and repair service business, and I offer small engine repairs, various garden tractor pulling parts and repair services, various Cub Cadet 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.

I 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 & 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.

To place an order and/or for technical assistance, please contact:

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 & handling. Because as of now, my web sites are not set up to accept orders online. I also do not have a parts catalog to mail out. So you'll have to print out my web sites.

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 packages and don't care. And when the work is completed, I'll either call or email you an invoice with the total including shipping & handling.

To figure the shipping cost, I weigh the package with the parts, then I go online to the USPS Postage Rate Calculator web site. 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 me 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. I do not ship anything COD. 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 elsewhere around the world:

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

We Accept PayPal, Visa, MasterCard, American Express & Discover Credit & Debit Cards Western Union - Send Money - Money Transfer - Find Location - Transfer Money
(When placing an order through PayPal, please specify which parts you need.)

To make a payment to me through PayPal, go to PayPal's web site ( https://www.paypal.com/ ) and click on [Pay or Send Money]. Type in my email address, or copy and paste this: pullingtractor@aol.com then 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 web site 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 comes 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.

High Speed Bottom Main Fuel Adjuster -

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 at wide open throttle. It provides no high performance engine enhancements whatsoever. It's an add-on feature only to prevent wearing or enlarging the fuel suction hole in the main jet by the OEM high speed needle adjuster due to normal engine vibrations at very high RPM or at 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, 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.

  • $17.00 each, plus shipping & handling.
New Brass Main Jet/Nozzle. Fits all Carter/Kohler #26, #28, #30 carburetors used on Kohler K-series and early Magnum engine models K241, K301, K321, K341, K361 and opposed (flathead) twin cylinder engines. Drilled for gas. 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 certain 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 (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 Main Fuel Mixture Needle Adjuster Screws for Carter #16, #18, #20, #22 Carburetors. NOTE: Certain high speed main 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 the absence of holes 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. 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, 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, or a bushing and new throttle shaft both must be installed. If there's a counterbore where the throttle shaft is, a flat bronze bushing can be installed, and if it's 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.

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" area on the throttle shaft. The original throttle shaft can be reused with the bushing if it isn't severely worn. To install the bushing, first of all, to avoid breaking off the OEM soft brass throttle plate screws, use a Dremel or equivalent small rotary grinder chucked with either a very 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 remove the shaft from the carburetor body. Clean out the counterbore and depending on size of carburetor, place the bushing over a 3/16" or 1/4" bolt and insert the screw of bolt in the throttle shaft 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 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 carburetors have no counterbore for the bushing, and sometimes 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-align bored with the [unworn] lower hole, and a bronze sleeve bushing will need to be installed along with a new 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. The throttle lever can be reused and welded to the new fabricated shaft. And if necessary, a slightly oversized shaft can be installed instead of the original diameter shaft. I can do all this for $50.00± parts and labor, plus return shipping & handling.


Bronze Throttle Shaft Sleeve Bushing for the newer Walbro WHG #52, #60, #64 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. NOTE: The upper throttle shaft hole must be precision-bored exactly to .3125" (5/16") in perfect alignment with the lower hole for installation of this bushing. 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.

New carburetors, and throttle and choke shafts for Kohler engine models K482, K532 and K582 have been discontinued by Kohler. Therefore, 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 use 1/4" cold rolled steel rod to make a new throttle shaft. 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 or braze the OEM throttle lever to the new shaft. I also install a felt 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.

  • The repair price is $75.00 - $100.00 per shaft for parts and labor, plus return shipping & handling.
  • When sending your carburetor to me, please package it securely so it won't get damaged in shipping and 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 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. IMPORTANT: Be sure to enclose the carburetor in a sealed zip-lock sandwich bag to prevent the odor of gas from escaping the package. If the odor of gas is still present from outside the package, apply an 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. Please send to: A-1 Miller's Performance Enterprises, 1501 W.

Universal Small Engine Remote Fuel Primer Kit. Safe to use and works flawlessly! With the fuel bowl atmospheric vent hole(s) plugged, 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 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 Neoprene Rubber Oil Seal installed in machined counterbore to keep dust and dirt out (which wears the bushing) and prevent film of oily mess on side of engine. (Vacuum within crankcase due to upward stroke of piston draws in dust and dirt, which attach to the oil in bushing, and pressure from the downward stroke of piston blows out a fine mist of oil, in overtime, builds up on outside of engine.) Seal fits snug in bushing and on shaft, and has no effect with operation of governor whatsoever. For Kohler engine models listed below Ê with bushing # 230476-S, 41 158 02-S or 235476-S. NOTE: When ordering, please specify part number of bushing or engine model and specification numbers.

12 Volt Low Pressure Electric Fuel Pump Kits. Small and compact. Replace faulty 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 yard and garden work, or for garden tractor pulling. Will work for most single- and twin-cylinder gas engines such as Kohler, Briggs & Stratton, Tecumseh, Wisconsin, etc., on virtually all models of Cub Cadet, John Deere, Wheel Horse, Sears Suburban, Massey Ferguson, and just about any lawn & garden equipment with a 12 volt electrical system. These electric fuel pump kits come with fittings that accepts 1/4" i.d. fuel hose, the same size that's on most Kohler and other makes and models of engines. If it's a Kohler AQS (Quiet Line) engine, the fitting in the carburetor would need to be changed to 1/4". If the engine has magneto or solid state 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.

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 flat 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 particles 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 ingenious and innovative concept by Brian Miller, because nobody else advertise this repair service.

  • 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 (atmospheric pressure) where the engine will be used, final idle and high speed air/fuel mixture adjustments will need to be made by the customer or an experienced small engine mechanic/technician so the engine will run smooth.

IMPORTANT: When sending your carburetor to me, please package it securely so it won't get damaged in shipping and 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 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. And be sure to enclose the carburetor in a sealed zip-lock sandwich bag to prevent the odor of gas from escaping the package. If the odor of gas is still present from outside the package, apply an 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.

The venturi in these carburetors can be bored so they'll have either a 7/8", 1" (.995" NQS legal) 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 (atmospheric pressure) where the engine will be used, final idle and high speed air/fuel mixture adjustments will need to be made by the customer or an experienced small engine mechanic/technician 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 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 1" (.995" NQS legal) venturi, if the engine is going to turn at 4,000± RPM, high RPM or at 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.

Conventional Ignition Parts - | Please contact me if you're interested in any of these parts or services.
Ignition Points. Fits Kohler engine models K90/K91, K141, K161/K160, K181, K241, K301, K321, K330/K331, K341, K361, KT17, KT17II, KT19, KT19II, K482, K532 and K582. Also replaces (without mounting bracket): Tecumseh part #'s 32011, 32011A, used on engine models HH80, HH100, HH120 with battery ignition; and Clinton engine models 414, 418, 420, 422. 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 without mounting bracket. $5.00 each, plus shipping & handling.
  • 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 w/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 for a hotter 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 (such as Cub Cadet). NOTE: For aftermarket points, the threads may need to be recut with a 8-32 UNF hand tap. An ingenious and innovative concept by Brian Miller.
  • .50¢ each, plus shipping & handling.
  • Install Hex Socket (Allen) Head Cap Screw w/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). Wrench measures 2-1/2" length x 7/8" wide. Made out of high strength black alloy steel.
  • $3.00 each, plus shipping & handling.


Phillips Head Screws w/lock washers for mounting of ignition points and points cover. Makes for easier fastening of points and cover to engine block than OEM slotted head screws in hard-to-get places. 10-24 UNC x 3/8" thread length.
  • High quality aftermarket. Phillips head. $1.00 per pair, plus shipping & handling.
  • OEM Kohler part # X-131-1-S. (Slotted head.) $1.70 each, plus shipping & handling.


Hex Socket (Allen) Head Cap Screws w/split lock washers for mounting of ignition points and points cover. Makes for easier fastening of points and cover to engine block than OEM slotted or Phillips head screws in hard-to-get places. 10-24 UNC x 3/8" thread length. Replaces Kohler part # X-131-1-S.
  • $1.00 per pair, plus shipping & handling.
Chevrolet (GM) V8 adjustable ignition points that can be used on the Kohler K-series 10hp-16hp and opposed (flathead) twin cylinder engines. NOTE: The "Chevrolet" points and condenser are actually made for the 1955-1974 General Motors cars and trucks 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 at 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 yard 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.
  • Chevy (GM) points only. $10.00 each, plus shipping & handling.

  • $133.35 each, plus shipping & handing.

NOTE: The magneto coil wrapped with varnish-coated paper (Kohler part # 210293), and the stator assembly and rotor 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 hot spark. Avoid using a high-output/performance coil because these draw more power from the battery.

Universal Magneto Ignition Coil for various engines with point/condenser and coil under the flywheel. For Kohler K-series flathead cast iron block, most smaller aluminum block Tecumseh and Clinton engines with coil/stator under flywheel. Replaces Tecumseh part #'s 29632, 30546, 30560, 30560A, 610768; Tecnamotor # 1633.0001; Kohler #'s 220435-S, 47 145 02-S, 47 755 20-S; Clinton # 135-13-990 and Phelon # FG-6240. 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 the NOVA 2, Mega-Fire or Kohler modules (see below ). The short wire on the coil is for ground, the longer wire connects to the points and condenser, 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 spark plug wire hump). 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 hot 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 coil. 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 for a hotter and more stable spark, quicker starts, and virtually trouble- and maintenance-free magneto ignition system.

NOVA 2, Mega-Fire and OEM Kohler Electronic Transistorized Ignition Modules - Return to a previous page or paragraph.
  • Upgrade the magneto ignition system on virtually any engine with the latest technology! Do away with the points and condenser, and install one of these solid state modules. It should be the end of the ignition problems. The points and condenser 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. The NOVA 2 and Mega-Fire modules have a durable die-cast aluminum housing. They all produce a hot 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, certain one or two cylinder outboard boat motors, etc., with points and condenser 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 certain outboard boat motors. Usually, the coil don't need replacing when substituting the points and condenser 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. 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 passes 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. The conventional points and condenser 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. Comes with detailed instructions. Click here for installation instructions.

Will not work with the older three-armature coil or any other type of coil. If swapping the three-armature coil for a newer two-armature coil, a newer flywheel will need to be used, too. NOTE: If no spark after installing the Magnetron™, the magnets in the flywheel will need to be re-polarized by Briggs & Stratton.

(When using two standard-capacity (Kohler) condensers, connect each condenser wire to the negative (–) terminal on the coil, or to the wire going to the points, and make sure that each condenser is properly grounded.) And most failures of battery-powered ignition coils is caused by overcharging of the electrical system due to a faulty [automotive] battery or faulty voltage rectifier/regulator.

New 1.8 Ohm Ballast Resistor for use with any 12 volt ignition coil not having an internal resistor (above È) to prevent premature burning of ignition points, use with the Chrysler ignition control module, or connect with coil having a 1.2 ohm internal resistor to prevent burning up the Dynatek or Pertronix ignition control modules. NOTE: Ignition resistors with a higher ohms value are known as "Point Savers." The higher the ohms resistance in an ignition coil or that 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 internal 3 ohm resistor connected to a minimum 1.8 ohm ballast resistor when used in a points/condenser 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 coil will still provide plenty of spark for an average engine. And this is best to used with general lawn and garden, snow removal, etc., and not for competitive pulling. Return to previous section.

Complete 7mm Diameter Spark Plug Wires with connectors and boots for above È coils. NOTE: The OEM Kohler spark plug wires rarely go bad or get weak. The only time they need replacing is when damaged beyond use. 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 Kits - When the OEM magneto or Kohler's breakerless ignition fails, install the battery-powered ignition system. This system last a long time and when something does go wrong, it's easily fixable. It's a reliable, simple design and there's no guesswork about it. FYI: battery-powered ignition conversion is intended mainly for 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 Engines - Convert from Magneto Ignition to Battery-Powered Ignition. Convert virtually any single cylinder, air-cooled cast iron or certain aluminum block small gas engine, such as Kohler, Tecumseh, Briggs & Stratton, etc., that originally came with a magneto ignition system (having points, condenser and ignition coil that has voltage generated by a permanent magnet in the rotating flywheel, instead of being powered by a battery or self-generating power source) into the battery-powered ignition system. Kit includes: New high quality aftermarket battery-type condenser, aftermarket standard-output/stock (20,000 volts) canister ignition coil with bracket and internal 1.5 ohm resistor, and aftermarket carbon-core spark plug wire. NOTE: Must use a universal automotive start/ignition key switch, or an ON/OFF toggle 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 hotter spark.

Single Cylinder Engines - Convert from Kohler's Breakerless Ignition to Battery-Powered (Points/Condenser) Ignition. Do away with Kohler's high dollar breakerless ignition components and install a low-cost and reliable battery-powered ignition system. Kit includes: New high quality aftermarket ignition points, aftermarket battery-type condenser, aftermarket points pushrod, Kohler points cover, Kohler points cover gasket, Kohler points cover wire grommet, four 10-24 UNC screws, aftermarket standard-output/stock (20,000 volts) canister ignition coil with bracket and internal 1.5 ohm resistor, and aftermarket carbon-core spark plug wire. Use the same ignition switch that came on the tractor or equipment. NOTE: Use a pointed #6 self-tapping sheet metal or drywall screw and a small nail puller pry bar to remove the brass block-off plug from points pushrod hole. Do not force the screw in the plug and push the plug inside the crankcase! Just gently thread it in a few threads, that's all it takes to pull out the plug. But if the engine block has a Briggs & Stratton points plunger plug, the plug can be removed by using a small nail puller pry bar as well. May have 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 hotter spark.

  • $75.40 per kit, plus shipping & handling.

Opposed (Flathead) Twin Cylinder Engines - Convert from Magneto Ignition to Battery-Powered Ignition. Convert Kohler engine models K482, K532, K582 or K660/K662 that originally came with a magneto ignition system (having points, condenser and ignition coil that has voltage generated by a permanent magnet in the rotating armature or flywheel, instead of being powered by a battery or self-generating power source) into the battery-powered ignition system. Kit includes: New high quality automotive (GM) condenser, high quality aftermarket Harley-Davidson (3 ohm) ignition coil (coil mounting bracket not included - discontinued from Kohler), and two high quality aftermarket spark plug wires. NOTE: Must use a universal automotive start/ignition key switch, or an ON/OFF toggle 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 hotter spark.

  • $80.50 per kit, plus shipping & handling.

NOTE: To convert the Kohler KT17/KT17 series 2 or KT19/KT19 series 2 engines into solid state ignition, use parts off a Magnum twin cylinder engine model MV16, M18, MV18, M20 or MV20. Parts needed are the flywheel, solid state ignition coil/screws and coil mounting bracket/screws. The flywheel is a direct replacement, but two holes will need to be drilled and tapped in the #1 cylinder is on your right when facing the flywheel) to mount the coil bracket. The bosses for the screw holes are already cast in the cylinder for this. And a different ignition switch will be required to ground the coil to shut the engine off. A simple OFF/ON toggle switch can be used. Check with your local small engine repair shops/salvage yards, search eBay, Craigslist or the Internet for the required parts.

New points, condensers, coils and spark plugs for other makes and models of engines are also available. Please call or email me for your needs. Please contact me if you're interested in any of the above È parts.

Crank Trigger Ignition Kit with Dynatek Dyna S or Pertronix Ignitor Module/Sensor for Single- or Opposed Twin-Cylinder Engines - (Added 1/20/16)

Virtually trouble- and maintenance-free, and water-proof. These ignition modules/sensors is a small, compact and complete self-contained electronic ignition system built with the latest state-of-the-art engineering. These crank trigger ignition setups have been thoroughly tested and proven very reliable for all classes of pulling engines. They're the same ignition used by top pullers everywhere. Reliable at high RPMs, and works flawlessly at the speed of electricity. The ignition control module and pickup coils/sensors are contained in the same sealed casing. Spark occurs when a small countersunk/embedded magnet or trigger screw in trigger rotor on crankshaft PTO end passes the module/sensor. Each must be used with an ignition coil that has a minimum of 3.0 ohm internal resistor (Bosch 12 volt blue coil, PerTronix Flame-Thrower 3.0 ohm coil, etc.) in the primary circuit, or a coil with a minimum 1.2 ohm internal resistor connected to a minimum 1.8 ohm ballast resistor (this would total 3 ohms of resistance). Using a coil with less than total of 3 ohms of primary resistance will cause the modules/sensors to overheat and the engine may misfire until it cools down, or the modules/sensors might fail prematurely. Unlike the competitor's, our universal flat mounting plate comes with holes drilled for Kohler engines, but can be adapted for use on a variety of other makes and models of engines by drilling new mounting holes. Mounting plate fastens on PTO end of engine block.

Easy to visually set static ignition timing for either module/sensor:

  1. Position the flywheel or starter pulley w/timing marks or timing tape to set the timing where it needs to be.
  2. Rotate the trigger rotor with magnet or trigger screw directly aligned with the small hump in the middle of module, and tighten Allen set screw securely in rotor.

Since the Pertronix Ignitor will create a spark down to zero RPM, the engine can be timed to a higher degree of accuracy.

  1. Set a voltmeter to a 12-volt DC scale.
  2. Connect the voltmeter from the negative (–) coil terminal to the battery negative (–) terminal.
  3. With power supplied to the ignition system, as the trigger rotor is rotated, the voltmeter should fluctuate between 1.2 volts and battery voltage.
  4. Spark occurs just as the voltmeter switches from 1.2 volts to battery voltage.
  5. Position the flywheel or starter pulley w/timing marks or timing tape to set the timing where it needs to be, tighten down the set screw in the trigger rotor, and and the engine can now be started.

Timing cannot be set while engine is running. Minimum clearance between rotor and module/sensor is .025" and maximum is .040". Module/sensor will not operate if gap is wider than .040". Do not allow module/sensor to make contact with rotor while engine is running!

Each kit includes a universal flat 6061 aluminum mounting plate with module/hall effect sensor installed, and 2-1/4" diameter x 3/8" wide aluminum trigger rotor with a countersunk/embedded trigger magnet or installed trigger screw and installed Allen set screw. Please specify diameter of crankshaft PTO end for trigger rotor. Most common diameters are 1" and 1-1/8", but 1-1/4" and 1-7/16" are rare. And most steel crankshafts have a 1-1/2" diameter PTO end.

IMPORTANT! Set air gap (clearance) between pickup coil or proximity sensor and magnet / trigger screw or pin at a minimum of .025" and no more than .250" (1/4") with a brass, plastic or paper (anything non-magnetic) feeler gauge. If gap is wider than .250", engine could misfire at high RPM or at wide open throttle due to normal engine vibration. And of course, direct metal contact will damage either unit. If gap is closer than .025", due to normal engine vibration, magnetic pickup coil or inductive proximity sensor could strike the trigger screw/pin (or disc) and damage could occur, rendering either one useless.

Each have 20% more wire windings than the early OEM Kohler starter, giving it 20% more cranking power. Draws less amps; a smaller battery can be used. Cranks engine about twice as fast and draws less amps than an ordinary starter. FYI - The aftermarket starter motors I sell are the same as OEM Kohler starters. Kohler just place a big markup on theirs because it comes in a Kohler brand box and the starter has the Kohler name stamped on it. Kohler part # 41 098 08-S.

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 off of 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 hotter 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!)

High Torque Upper-Mount (mounting bolts are underneath starter) Gear Starter Motors for Kohler engine models K241, K301, K321, K341 and K361 engines. 12 volt.

Each have 20% more wire windings than the early OEM Kohler starter, giving it 20% more cranking power. Draws less amps; a smaller battery can be used. Cranks engine about twice as fast and draws less amps than an ordinary starter. Length: 7-1/4"; mounting studs: two 1/4"-20; o.d. housing: 3-1/16"; center to center mount: 2-1/2"'. FYI - The aftermarket starter motors I sell are the same as OEM Kohler starters. Kohler just place a big markup on theirs because it comes in a box with the Kohler name on it and the starter has the Kohler name stamped on it. Kohler part # 41 098 06-S.
  • New high quality aftermarket starter. Comes with a 100% unconditional one year warranty. $85.00 each, plus shipping & handling.
  • New OEM Kohler starter. Comes with a 90 day warranty against defects in materials or workmanship. $207.35 each, plus shipping & handling.

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 off of 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 hotter 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!)

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

NOTE: High-quality ring sets, pistons and piston/rings assemblies are also available for other makes and models of small gas engines. And the piston assemblies that's offered here will work with a stock connecting rod and crankshaft without the need for rebalancing. And always match a billet connecting rod of a certain length to an aftermarket piston (Arias, JE, etc.) that has the correct compression height. These two parts must be matched for the piston to come flush with the top of the engine block, or have a few thousands of an inch pop-out. If using a Kohler connecting rod, the compression height may not be correct with an aftermarket piston (Arias, JE, etc.) that has the wrong wrist pin offset. The same is true with a Kohler piston and a billet connecting rod of a the wrong length. You can find piston ring compressors on eBay.
NOTE: Complete engine rebuild kits are available, but a kit will cost more than if the parts were purchased separately. So please contact me with a list of parts you need, and I'll get back to you with a total amount including shipping & handling. And if you need a part or parts that's not listed here or for other make and model of engines, please contact me and I'll see if I can get it at a reasonable price. Please contact me if you're interested in any of the above È parts or items.

New and Used OEM 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 K-series K90/K91 engine. 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 then if the original rod isn't badly scored or burnt, it can be resized to fit to odd-size undersize journal.

Connecting rods for Kohler engine models K482, K532, K582 and K660/K662 have been discontinued from Kohler. I don't stock these rods. Used and NOS (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 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 & Automotive Machine Shop, 14 Bus. Loop 70 East, Columbia, Missouri 65203 USA. Phone: 1-573-449-0893. Email: vjnen@centurytel.net. He can bore these rods and install the MG bearing inserts, or regrind crank journals and resize rods for a reasonable price.

Or, being the K241 and K482 engines share the same pistons and have the same stroke, and their connecting rods are the same length, a K241 connecting rod can be used in a K482 engine when bored and honed to 1.625" - 1.626" to match the STD size K532 or K582 crank journal, which are 1.624" (allow .001" - .002" for oil clearance). If the K482 journals are worn and reground undersize, the K241 rod can be bored and honed to fit the undersize journals. The oil dipper will need to be cut off, too. And being the K301 and K321 engines share the same pistons and have the same stroke as the K532 and K582 engines (respectively), and their connecting rods are the same length, a K301, K321 or even a K341 connecting rod can be used in a K532 or K582 engine when bored and honed to 1.625" - 1.626" to match the STD size K532 or K582 crank journal, which are 1.624" (allow .001" - .002" for oil clearance). If the K532 or K582 journals are worn and reground undersize, the K301, K321 or K341 rod can be bored and honed to fit the undersize journals. The oil dipper on these rods will need to be cut off as well. Boring these single cylinder engine rods will not weaken them whatsoever because they hold up very well when bored and used with bearing inserts in the respective single cylinder engines.

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 (piston flush with top of block) or offset .020" or more (up to .125" at no extra charge) 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 yard work, stock or high RPM pulling competition 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 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".

  • Exhaust. OEM Kohler part # 220009-S. $38.15 each, plus shipping & handling.

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

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

NOW AVAILABLE! Exact Duplicate of the Popular and Sought After OEM Kohler K361 18hp OHV 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 (.325"), but a little less duration than the 4,000± RPM reground torque cam below Ê, which makes it perform best at slightly lower RPM. This cam builds up the compression about 4% more at 3,600 RPM than the stock flathead engine cams. It's ideal for general yard 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 unground 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 either side of the base circles of the lobes so they can't be readily seen. 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 yard and garden work. When used for competition pulling, this cam performs best with a set of medium performance (blue) 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 made 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 3,800 - 4,500 RPM. At high 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!

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 unground 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 either side of the base circles of the lobes so they can't be readily seen. 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.

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 (.325"-.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. 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.

Medium Performance (Blue) Single Valve Spring Set for Kohler engine models K241/M10, K301/M12, K321/M14, K341/M16 and K361. These are more aggressive than OEM stock 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. 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.

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

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: 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 seen 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, 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. (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 Threadlocker 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. Accept no copycat parts!

Reconditioned OEM Kohler Crankshafts - [When available]

Available for Kohler engine models K241/M10, K301/M12, K321/M14, K341/M16or K361. These cast iron cranks are genuine 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. For accuracy, measure the length from the oil seal shoulder out. If you have the engine's original model and specification numbers, go to kohlerplus.com (requires Internet Explorer), to find the correct part number for the crankshaft, then find the dimensions and specifications of the crankshaft is here: CRANKSHAFT REFERENCE MANUAL.

Proposed Engine Dyno Service: $50.00 per hour run time. No setup fee for Cub Cadet engines with a 3- or 6-pin clutch driver. An adapter may need to be used or fabricated for other makes and models of engines. As soon as this service is available, it'll be posted here.

Precision, Dynamic Flywheel and Crankshaft Spin-Balancing Service. To balance the rotating assembly, the crankshaft, piston/rings, pin, clips, connecting rod and bearing inserts (if applicable) are all required. The flywheel is balanced separately.
  • Balance (cast or steel) flywheel for Kohler 10-16hp cast iron block engine. $60.00 labor, plus return shipping & handling.
  • Balance flywheel for other make and model of engine. I will need to make a spindle with a tapered end/bolt hole to match the taper in the flywheel to spin the flywheel. $85.00 labor, plus return shipping & handling.
  • Balance single cylinder cast OEM Kohler crankshaft. $150.00 for welded weight plate and labor, plus return shipping & handling.
  • NOTE: Usually, a steel plate (of various thicknesses) is welded on the side of the counterweight that's next to the gear on the crankshaft to balance it. This is the easiest way to balance a Kohler crankshaft. But on other makes of crankshafts where there's no room for the balance plate, holes would need to be drilled crossways through the counterweights, and tungsten steel plugs will need to be welded in the holes. To do this, the price will be around $400.00 per crankshaft, plus return shipping & handling.

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

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

  • New OEM Kohler part # 235376-S. $116.55 each, plus shipping & handling.

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.

Complete Exhaust Header Pipe Kits - Top of page | Please contact me if you're interested in any of these parts or services.
Exhaust Port Repair/Modification Services. (K141, K161, K181/M8, K241/M10, K301/M12, K321/M14 or K341/M16 Kohler engines.)

Resurface end of exhaust port to remove heavily rusted/distorted surface and create smooth, even surface to ensure proper sealing of muffler or exhaust flange, and that header bolts will stay tight and not possibly break off due to normal engine vibration. NOTE: Crankshaft and bearing plate will need to be removed from engine block. Then with block fastened directly to table or in a V-shaped fixture fastened to the table of my milling machine, I make several passes with a grinding stone to resurface end of exhaust port.

  • $20.00 labor, plus return shipping & handling.

Drill holes and cut new threads for two new 5/16"-18 UNC bolts in end of exhaust port to install bolt-on muffler or header pipe flange. NOTE: Crankshaft and bearing plate will need to be removed from engine block so I can fasten block directly to table or in a V-shaped fixture to the table of my milling machine.

  • $40.00 labor, plus return shipping & handling.

Remove or drill out broken exhaust port mounting bolt(s) or studs and recut 5/16"-18 UNC threads for installation of new bolts or studs. NOTE: If broken fastener(s) needs to be drilled out, crankshaft and bearing plate will need to be removed from engine block so I can fasten block directly to table or in a V-shaped fixture to the table of my milling machine.

  • $10.00-$40.00 labor (depending on difficulty of work involved), plus return shipping & handling.

IMPORTANT! When making new threads in the block to mount the adapter for the header pipe, being cast iron is hard material, and to prevent from breaking off a (plug) tap in the hole, it's best to start the thread cutting process with a TAPER hand tap, then finish with a PLUG hand tap so the threads of the mounting bolts will reach deeper in the holes.

Bolt-On/Clamp-On Exhaust Header Pipe Kits - Top of page

Exhaust Port/Flange/Hub Header Pipe Bolt-On Adapters. Hub has beveled edges for smooth, uninterrupted exhaust flow. Designed for use on Cub Cadets 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 the bolts won't 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, it makes for a professional-looking job because the silicone can't be seen. The flange/hub is also small enough to clear the governor lever. NOTE: If your block don't have two 5/6-18 UNC mounting 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.

Resurface end of exhaust port to remove heavily rusted/distorted surface to create smooth, even surface to ensure proper sealing of muffler or exhaust flange, and that the bolts will stay tight. NOTE: Crankshaft and bearing plate will need to be removed from engine block. Then with block fastened directly to table or in a V-shaped fixture fastened to the table of my milling machine, I make several passes with a grinding stone to resurface end of exhaust port.

  • $20.00 labor, plus return shipping & handling.

Drill holes and cut new threads for two new 5/16"-18 UNC bolts in end of exhaust port to install bolt-on muffler or header pipe flange. NOTE: Crankshaft and bearing plate will need to be removed from engine block so I can fasten block directly to table or in a V-shaped fixture to the table of my milling machine.

  • $40.00 labor, plus return shipping & handling.

Remove or drill out broken exhaust bolt(s) and recut 5/16"-18 UNC threads for installation of new bolts or studs. NOTE: If broken bolt(s) needs to be drilled out, crankshaft and bearing plate will need to be removed from engine block so I can fasten block directly to table or in a V-shaped fixture to the table of my milling machine.

  • $10.00 - $40.00 labor (depending on difficulty of work involved), plus return shipping & handling.

IMPORTANT! If two new 5/16" bolt holes needs to be made or repaired due to broken bolts/studs in the end of exhaust port to mount a bolt-on muffler or header pipe flange, this should be performed by an experienced machinist with the engine block bolted to a fabricated angled fixture securely fastened on the table of a large milling machine so the holes can be drilled precisely in the exact locations. Then the threads can be cut with a hand tap. Because if the hole(s) are drilled crooked or out of alignment (with the holes in the muffler or flange), or if the drill bit or threading tap breaks off in the hole, this could be the beginning of a living nightmare!

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 & they guarantee their repairs.

Crankshaft Repairs -
  • Remove burnt aluminum and polish journal to shiny finish. $10.00 each journal. I chuck the crankshaft in my big metal lathe, turn it on slow and use my crankshaft polisher with a sanding belt to remove the burnt aluminum. This works great until the aluminum is gone, but sometimes the journal is scored or worn. Then it requires regrinding to the next undersize. If it's not scored or worn, then it can be reused as is. But if it is worn, an undersize rod and possibly one with a bearing insert is required. If it does need regrinding, then there's no charge for cleaning it.
  • Regrind journal (crank pin) to next undersize. $60.00 per journal. NOTE: Kohler crankshafts can be reground to .030" undersize and still be safe to use with matching undersized 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.
    • Once installed and in operation, there is no warranty or guarantee of any kind on crankshaft regrinds.
  • 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. The cost for having this done is $100.00 labor for a single cylinder engine, and $200.00 for a two cylinder engine, plus return shipping & handling. If you're interested, I will need your crankshaft and connecting rod(s). An innovative concept by Brian Miller, because nobody else advertise this service .
    • Once installed and in operation, there is no warranty or guarantee of any kind on crankshaft regrinds.
  • Repair broken off 5/8" stud on flywheel end of crankshaft. Center drill and cut threads for a 3/8" diameter grade 8 bolt in the end of crankshaft. $25.00 labor, plus return shipping & handling.
  • Drill hole and cut 7/16-20 UNF threads in the PTO end of the crankshaft for bolt and flat washer. $25.00.
Install Bearing Inserts in Connecting Rods for Kohler engine models K241/M10 (10hp), K301/M12 (12hp), K321/M14 (14hp), K341/M16 (16hp), K361 (18hp OHV) M20 and MV20. Rods must be bored and notched to accept bearing inserts. Clevite CB278P/CB279P or Sealed Power 9885CP/9885CPA bearing inserts will be installed. Please indicate diameter of crank journal for size of bearing inserts. (STD size, .010", .020" or .030" undersizes.) Also, rods can be bored centered for top of piston to come flush with deck, or bored .020"± offset for 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 & handling.
  • Bore your rod only (customer supplies and installs own bearing inserts): $25.00 labor, plus return shipping & 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 & 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 & 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 (piston flush with top of block) or offset .020" or more (up to .125" at no extra charge) 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 yard work, stock or high RPM pulling competition 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 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 & 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 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 trained to repair newer aluminum block engines. 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 though. Anyway, I just want to let you know this so you won't think I sell junk.
  • K141, K161 and K181bare blocks with 2-15/16" bore. $40.00 each, plus shipping & handling.
  • K241 bare block. $65.00 each, plus shipping & handling.
  • K241 bare block with 10hp bore and K301 embossed on the PTO end. (Extra thick cylinder wall.). $200.00 each, plus shipping & handling.
  • K301 bare block. $125.00 each, plus shipping & handling.
  • K321 bare block. $150.00 each, plus shipping & handling.

  • K341 (16hp - 13 fin) bare block. $400.00 each, plus shipping & handling.
  • Packaged shipping weight for each block is 45 lbs.

The Major Differences Between the K241/M10, K301/M12, K321/M14 and K341/M16 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/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/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.

Kohler engine blocks are not like the small block Chevy V8, they're not all the same. There are many other variations between the Kohler K241/M10, K301/M12, K321/M14 and K341/M16 blocks. If replacing an engine, the best thing to do is have the original engine rebuilt, then all the accessories will attach to the engine with no problems. But if the block is not rebuildable and damaged beyond repair, another block of the same type will need to be acquired. If interested in purchasing a bare block, please email me several detailed, sharp pictures of your block at various angles so I match it to one I may have in stock.
  • 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. 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 come with balance gears and some didn't. Some have an expansion plug where balance gear stub shafts can be installed, and some have no holes drilled for the stub shafts.
  • All Magnum blocks don't have the provisions to mount 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 -

I 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 despite 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.

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.

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!

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. But I was thinking, I may have to give up on building these engines from scratch. May have to have my customers bring or send their complete engines to me for building or rebuilding. - Brian Miller

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

Competition Pulling Engine Freshening Service Ê Top of page

A typical pulling engine will last an average of 25 pulls or 3 years of use. After that, it may start to lose power when under load and puff smoke out the crankcase breather vent and/or out the exhaust. When this happens, it's time for a freshening job. 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.

NOTE: The Stock-Altered class engine is very much like the 16hp Hot-Stock engine, except these engines burn methanol, the carburetor is restricted to a 1" venturi with a maximum 1" thick mounting spacer, and is allowed to use a billet cylinder head. The Stock-Altered engine may also have either an OEM Kohler or aftermarket (MSWC) engine block. Other than that, these two engines are basically the same. These engines runs at wide open throttle (no governor); has a 9-1/2" 25 lb. heavy steel flywheel; high torque upper-mount gear starter; A-1 Miller's Hot-Stock/Stock-Altered welded-up and reground cast high performance camshaft; single high performance valve springs; performance valve job with stock size valves; #26 Kohler carburetor, venturi bored to 1", reworked, set up for methanol with bottom adjuster and velocity stack; enlarged ports and polished (where applicable); billet cylinder head milled; billet connecting rod with bearing inserts; rotating assembly (crankshaft and connecting rod/piston assembly) precision spin-balanced to reduce engine vibration. Also included are: flywheel shroud (not chromed), cast iron oil pan, bolt-on header pipe and conventional Kohler point ignition system installed with ignition timing preset. Upon receiving engine, install in tractor, add fluids and engine will be ready to start after all connections are made. Carburetor adjustments will be initially preset, but due to different altitude levels, final adjustments may need to be made after engine is started. IMPORTANT: Scroll down for proper break-in (wear-in) oils and procedure for fresh-built pulling engines.

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.

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. Contact Precision Plating of Quincy to have your parts chrome-plated.

Break-In (Wear-In) Oils and Procedure for Ordinary Rebuilt (Lawn & 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. Do not allow the engine to idle at a slow speed for a long period of time to break it in! It needs to run at full governored speed so the crankcase oil can splash 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. Run the engine normally for 4-5 pulls. Do not allow the engine to idle at a slow speed for a long period of time to break it in! It needs to run at full governored speed or at a fast idle (on a non-governored engine) so the crankcase oil can splash 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 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 or one automotive (GM) condenser. This is so the coil will produce full 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 yard 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 & need rebuilding or reconditioning, such as the gear starter, cylinder head(s), crankcase breather assembly, fuel pump & 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 web site 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 & 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.

Single & Double Clutch Assemblies for an IH Cub CadetClutch Parts and Rebuilds. For pulling competition, heavy towing, garden plowing, pushing snow, yard work or just lawn mowing. It's possibly the last clutch your tractor will need! I also rebuild plain stock OEM Cub Cadet 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 locking collar will be used instead. For competition pulling, it is recommended that a locking 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 Cadets 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 Cadets -

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" -

For all other models of Cub Cadets -

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


Clutch Drive Studs w/Nuts 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 60º 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.


High quality aftermarket fiber material clutch disc for Cub Cadet garden tractors. Provides about 70% more grip than stock Cub Cadet fiber clutch disc. Drop in replacement of OEM Cub Cadet clutch disc. Can be used with a 3- or 6-pin drive plate. Replaces Cub Cadet part # 961-3002.

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 edge of the disc is turned true in my metal lathe, then the 6 holes are precision-drilled using my milling machine in an 8" super spacer with a 6-notch masking plate. Unlike the competition that offer the same copycat part, the drive holes in my aluminum discs are drilled to 13/32" to reduce clutch rattle and less chance of breakage to the drive pins.

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!

5/8" i.d. Zinc-Plated Steel Split Lock Washer and Steel Spacer. Replaces teasing spring on all Cub Cadet narrow frame clutch drive models 70, 71, 72, 73, 100, 102, 104, 106, 122, 124 and 126. NOTE: Lock washer not for use with OEM Cub Cadet clutch pressure spring. Use only with high pressure red (800± lb.) or yellow (1,150± lb.) spring.

Coming Soon! A-1 Miller's own CNC-machined 6-hole aluminum clutch discs. Projected price: $15.00 each, plus shipping & handling. As soon as this part is available, it'll be posted here.


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 vibrations, 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 at 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 & 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 & handling.

Lubricating Sleeve with Grease Fitting for short clutch release/throw-out bearing above Ê. 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 main pressure spring. Also allows for easier and smoother clutch pedal depression. Grease fitting is offset in sleeve and goes toward spring for easier access. Sleeve installs between clutch release/throw-out bearing and main pressure spring with grease fitting rearward, toward spring for easy access. Heavy wall tubing measures .626" i.d. x 1" o.d. x 3/4" length. Third spiral pin hole or split locking collar(s) behind pressure spring will need to be located 3/4" 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.

High Pressure Clutch Springs -

800± lb. "Red" Spring, and 1,150± lb. "Yellow" Spring for all models of clutch-drive Cub Cadets. Suitable for heavy yard/garden work or snow removal and/or Stock, Hot-Stock, Stock-Altered, Super-Stock, 50 c.i. Pro-Stock and 50 c.i. Modified Class competition pulling tractors. Ideal for use with aluminum clutch disc or double fiber clutch disc setup. These springs are a direct replacement for OEM Cub Cadet clutch pressure spring. The OEM clutch release lever may need to be extended 3" with either of these springs for easier clutch pedal depression. Depending on type of clutch, the Red spring is suitable for Hot-Stock and Stock-Altered tractors, and the Yellow spring is suitable for 16hp Missouri Super-Stock, Pro-Stock and Modified tractors. When installing either of these springs, use the original 3rd spiral/roll pin hole in the driveshaft, which should measure 9-1/4" - 9-3/8" from the very front of the driveshaft, or install one or two split locking collar(s) at 9-1/4" - 9-3/8" from the very front of the driveshaft with a pillow block bearing support to reduce chance of driveshaft breakage at wide open throttle operation. Dimensions of each spring: 5/8" i.d. x 1-1/4" o.d. x 6" length.

  • $15.00 each, plus shipping & handling.
5/8" i.d. Split Locking Collar. With the absence of a drilled 3rd spiral pin hole, 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 at wide open throttle. Position locking 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). Has two Allen head screws that holds the clamp together and provide a very tight uniform 360° grip around the driveshaft. NOTE: It's best to use two locking collars on a stainless steel driveshaft because just one might slip on the "slick" and hardened surface of stainless steel.

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 60º 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.

  • When placing order, please specify if you need 3 or 6 studs installed. And when using the 6-pin drive plate, three additional holes must be drilled in the clutch disc(s) to match the location of the six drive studs.

NOTE: Before installing the driveshaft/clutch assembly in the tractor, apply automotive grease inside the pilot bushing and on the front of the driveshaft. Because if it's dry, the driveshaft won't release, it can bind up and wear both the bushing and driveshaft. And when using the 6-pin drive plate, three additional holes must be drilled in the clutch disc(s) to match the location of the six drive studs.

Heavy Duty, All Steel PTO-Driven Clutch Drive Plate for when the engine is reversed in a Cub Cadet!

NOTE: Before installing the driveshaft/clutch assembly in the tractor, apply quality automotive lubricating grease inside the pilot bushing and/or on the front of the driveshaft. 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 at 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 Adjustable Pulling Hitch Assemblies for Garden Pulling Tractors and 1,500 lb. Small Wheel Mini Rods. This is the design that's NQS legal, and 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 upper and lower support brackets are made of 1/8" thickness x 2" x 2" x 6" mild angle steel.
  • The two coarse-thread mild steel adjusting rods are 3/4" in diameter. Each rod is securely double-welded to the upper bracket.
  • Drawbar is made of 1/2" x 2" x 6" flat steel. It has a 1-1/2" hole for hook and there's 3/4" of metal from the front of drawbar to front of hole.
  • The hitch fastens directly to the Cub Cadet transaxle housing. Center of the 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, which are used to adjust the hitch height.
  • Assembly weighs approximately 6-1/2 lbs.
  • All bare metal, except the threaded rods and nuts, are coated with gray primer.
  • Garden Tractor hitch. $65.00 each, plus shipping & handling.
  • Mini-Rod hitch. Constructed much like the garden tractor hitch, except is 8" wide, has 1/4" thick upper and lower angle brackets, 7/8" diameter threaded rods with 4 adjustment nuts, and a 3/4" thick x 3" wide drawbar with a 1-1/2" hole for hook. $85.00 each, plus shipping & handling.


Drawbar alone with a 1-1/2" hole for garden tractor hitch (no holes for adjustment rods), measures 1/2" x 2-1/2" x 6" is $25.00 each, shipping included. Made of mild steel.

Coming Soon! A-1 Miller's own CNC-machined high quality 100% steel steel pulling hitch w/adjustable drawbar. Projected price: $40.00 each, plus shipping & handling. Drawbar alone w/holes: $15.00 each, plus shipping & handling. As soon as I have these parts available, there'll be posted here.

  • $10.50 each, plus shipping & handling.


Heavy duty, aircraft quality, ball joint end (Heim joint). Has a 3/8-24 UNF right-hand female threaded hole and a 3/8" i.d. hole. Can be used on most garden tractors, go-karts and custom automotive transmission shifter linkage ends. Replaces Cub Cadet part # 923-3018. 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 yard work 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 smoother and last longer.

  • $11.00 each, plus shipping & handling. Part # 170-166

Cub Cadet Transaxle Parts, Transaxle Rebuilds/Modifications and Machine Shop Services

Top of page

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.
A-1 Miller's Performance Enterprises is an Authorized Dealer for the Super Tough TRUE GEAR Pulling Gears and Hardened Top Shaft!

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 yard and garden work to speed up or slow down tractor. Made by True Gear & 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 web sites with large files.)

  • Above gears, any combination. $120.00 per set, plus shipping & 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.

NOTE: If preferred, a thin bead of clear RTV silicone adhesive sealant can be used instead of gaskets, for a more rigid and leak-proof transaxle. By the way - Instead using of gaskets, I applied clear RTV silicone adhesive sealant on my own personal pulling tractor Cub Cadet transaxles in 1989, and to this day, they haven't leaked a drop of oil. I've always preferred to use clear RTV silicone adhesive sealant for three reasons: 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 seen between the parts.

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 & handling.

To figure the shipping cost, I weigh the package with the parts, then I go online to the USPS Postage Rate Calculator web site. 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 elsewhere around the world:

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. Item(s) weighing over 67 lbs. or more is sent by FedEx Ground or equivalent services.
