NOTE: To place an order, please call the number below Ê or send an email (below) with a description of the parts or services you need and I'll respond with the total amount including 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 (books) available at this time. You'll have to print out my web sites. I contacted some book companies and they said being all my information is online at no charge, they don't think the books would sell well.

Everything in this web site is up-to-date and still available. Updates are made only when there's a change for a listing of a part. If a part is no longer available, I remove it. I shop around for high quality parts and try to find the best prices available, so prices are subject to change without notice. I'm also in the lawn mower/small engine repair business. So I can 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. No seconds or blems being pawned off on unsuspecting customers. Optimized for 1024 x 768 screen resolution.

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. And as far as some parts being no longer available - 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.

New Brass Main Jet/Nozzle. Fits all Carter or Kohler #26, #28, #30 carburetors used on Kohler K-series and early Magnum engine models K241 (10hp), K301 (12hp), K321 (14hp), K330/K331 (12½hp), K341 (16hp) flatheads, K361 (18hp OHV) and twin cylinder cast iron block 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 or 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.

High Speed Main Fuel Mixture Adjuster Needle Valves 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 the carburetor and found that some are in fact different. Therefore, if a wrong high speed needle adjuster is used in a particular carburetor, the engine may not idle correctly, idle too rich, or might not idle at all. Also, if the tip of your high speed needle adjuster is slightly bent, it can be easily straightened with pliers and reused, and will not effect engine performance whatsoever. But if it's damaged from being overtightened, it will need to be replaced. And if the tip is not exactly centered with the hole in the main jet/nozzle, this will also not effect engine performance whatsoever.

Throttle Shaft Bushings -
A worn throttle shaft is the #1 cause of most engines wearing out 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.
Bronze throttle shaft bushing Bronze Throttle Shaft Bushing for Carter #16, #18, #20, #22 carburetor used on Kohler engine models K90 (3.6hp), K91 (4hp), K141 (6¼hp), K160 (6.6hp), K161 (7hp) and K181/M8 (8hp), as well as other makes and models of engines. Professionally made in the USA of precision CNC machined bearing bronze. Dimensions: .213" i.d. x .407" o.d. x 1/8" height. NOTE: Some early Carter carburetors have a smaller diameter throttle shaft, which is .213" (#3 [drill bit]). This bushing is made for the smaller shaft. If a carburetor has the bigger 7/32" (.219") shaft, once installed, the bushing will need to be carefully drilled or reamed larger to 7/32". Also, some newer Carter carburetors do not have the counterbore to accept this bushing. If there's no counterbore, then either a new throttle shaft (see below Ê) will need to be installed, or if the shaft hole is severely worn, it will need to be slightly enlarged to match a fabricated oversized throttle shaft. I offer this service, too. Apply clean motor oil on throttle shaft before installing for smooth throttle action and less wear to shaft, bushing or carburetor body. No Kohler part number.

Bronze throttle shaft bushing Bronze (Short) Throttle Shaft Bushing for all Carter or Kohler #26, #28, #30 and early Walbro #52, #60, #64 carburetors used on Kohler K-series and early Magnum engine models K241/M10 (10hp), K301/M12 (12hp), K330/K331 (12½hp), K321/M14 (14hp), K341/M16 (16hp), K361 (18hp OHV) and KT17, KT17II, KT19, KT19II, KT21, MV16, M18, MV18, M20, MV20. Professionally made in the USA of compressed sintered bronze. Dimensions: 1/4" i.d. x 7/16" o.d. x 1/8" height. NOTE: Apply clean motor oil on throttle shaft before installing for smooth throttle action and less wear to shaft, bushing or carburetor body. Kohler part # 25 158 02-S.

  • Aftermarket. $5.00 each, plus shipping & handling.
  • OEM Kohler part. $9.65 each, plus shipping & handling.
  • Installation Service: Install this throttle shaft bushing in your carburetor. $30.00 each for bushing, new screws and labor, plus return shipping & handling. Please contact me if you're interested in this repair service.

Installation Instructions: If it isn't severely worn, the original throttle shaft can be reused with the above È bushings. The bushing makes contact with the upper unworn 1/8" area on the shaft. To install the bushing, remove the two small brass screws that secures the throttle plate to the shaft, then remove the shaft from the carburetor body. Clean out the counterbore and depending on the size of carburetor, use a 3/16" or 1/4" bolt and small hammer to squarely drive the bushing into the counterbore, and then reinstall the shaft. To prevent breaking off the throttle (or choke) plate screws, grind the flared ends with a Dremel or equivalent small grinder chucked with a chainsaw sharpening stone. Should a screw break off while attempting to remove it, sometimes the shaft can be difficult to remove. In this case, use the Dremel to grind the flared end of the [broken] screw so it is flush with the throttle shaft. Then the shaft can be removed, and the broken screw can be drilled out with either a 5/64", #46 or 2mm drill bit and retap the threads. The OEM screw size is 3-48 NC. Should the threaded hole become enlarged from drilling out the broken screw, then a larger screw (4-40 NC) will need to be installed. In this event, contact me and order the larger screws with split lock washers. Liquid threadlocker is not required. The bronze bushing is easy to install. Just clean out the counterbore and slide the bushing on a short 1/4" bolt (to guide the bushing straight into the hole), place the bolt with the bushing in the hole and use a medium size hammer to drive it in until it bottoms out. Then apply clean motor oil on throttle shaft before installing for smooth throttle action and less wear to shaft, bushing or carburetor body.

Additional Note: Usually a bronze bushing will snug up a worn throttle shaft. The bushing should last a long time, too. If the bushing fits somewhat loose in the counterbore, tap the sides of the counterbore with a hammer to close it up slightly. In other words, make the counterbore slightly egg-shaped. But don't mash the metal in too much. Just a slight tap on either side should do. But the newer Walbro carburetors have no counterbore for the bushing. Therefore, sometimes the throttle shaft hole in the carburetor body will wear, too. When this happens, installing a new shaft won't fix the problem. The hole must be accurately bored and a bronze sleeve bushing will need to be installed with a new shaft, or if the hole is not worn, sometimes the original shaft can be reused. But if the original shaft is worn and a new throttle shaft isn't available for a particular carburetor, then one must be machined from scratch. And if necessary, a slightly oversized shaft can be installed instead of the original diameter shaft. I can do this for $50.00 parts and labor, plus return shipping & handling.

Bronze Sleeve Throttle Shaft Bushing for the newer Walbro WHG #52, #60, #64 carburetors that have no counterbore for the short throttle shaft bushing. Dimensions: 1/4" i.d. x .313" o.d. x 3/4" long. NOTE: The upper throttle shaft hole must be precision-bored to exactly .3125" (5/16") in perfect alignment with the lower hole for installation of this bushing. Apply clean motor oil on throttle shaft before installing for smooth throttle action and less wear to shaft and bushing. Not to be used in the Kohler-made carburetors for Kohler engine models K482, K532 or K582. Because in order to install the sleeve bushing, there must be enough metal around the worn throttle shaft hole so when boring the hole to 5/16" (for the bushing), and when installing the bushing, the metal won't break out. If the throttle or choke shaft(s) holes are worn in a K482, K532 or K582 carburetor, the carburetor body can be machined for installation of bronze bushings (for choke shaft) or a fabricated/oversize throttle shaft. I've performed many of these shaft repairs on carburetors with success. If you're interested, I can repair yours as well. For dimension measurements, I will need the complete carburetor with the throttle shaft and throttle plate. The repair price per shaft is $65.00 for parts and labor, plus return shipping & handling. Please contact me if you're interested in this repair service. 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.

NOTE: The protruding pin will need to be ground flush with top of carburetor body and a 9/64" or #29 (drill bit size) hole will need to be drilled through carburetor body and 8-32 NC threads cut for installation of the idle speed adjusting screw. And apply clean motor oil on shaft before installing for smooth throttle action and less wear to shaft, bushing or carburetor body.
  • $23.00 per kit, plus shipping & handling.
NOTE: If an OEM Kohler throttle lever has a ball/stud pressed on it, and if the same throttle linkage is going to be reused, the ball/stud will need to be transferred to the new lever by grinding away the flared metal underneath and then place a small bead of weld under the ball/stud to secure it in place on the new lever. Or a new ball w/threaded stud that's listed in this web site can be purchased from me. Also, the holes in the OEM Carter or Kohler [steel] throttle plates, which have an 11/16" spacing for the #26, #28, #30 carburetors, will need to be slightly elongated with a Dremel or equivalent small grinder to match the holes in the 47 144 36-S Walbro throttle shaft, which have a 3/4" spacing. And when installing either throttle plates, with the carburetor float area facing downward, install the plate with the stamped numbers or letter(s) facing outward and toward the right of the throttle bore (as shown above È). And use split lock washers with throttle and choke plate screws to prevent screws from loosening and possibly becoming lodged in intake valve or on top of piston, which could cause severe damage. This is why I recommend using them. Liquid threadlocker is not required with lock washers.

Carburetor Repairs - YOUR 10hp-18hp Carter, Kohler or Walbro carburetor: 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. I'm not saying this happens with all engines, only the majority of them.

Modifications for the 10-18hp Kohler CarburetorBasic rebuild with no "high-performance" modifications whatsoever, according to the condition of the carburetor, the repair price is minimum $55.00 for parts and labor, plus return shipping & handling. This includes cleaning carburetor and installing a new overhaul kit. Any additional parts or services are an extra charge. Work includes whatever parts and services it may need that's listed below Ê. 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 we have any questions), a description of what you want done and any other parts you may need. And be sure to enclose it in a sealed zip-lock sandwich bag to prevent the gas odor from escaping the package. If the odor of gas can still be smelled from outside the package, then apply perfume, cologne or Febreze® 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. And we'll call or email you when it's repaired.

I've performed many of these shaft repairs on carburetors with success. If you're interested, I can repair yours as well.

Please contact me if you're interested in this repair service.

Rebuilt, reworked and modified only for high-performance use, #26 Carter or Kohler carburetors. 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 your altitude, you will need to make the final adjustments so the engine will run smooth.

NOTE: These carburetors are designed for use on Stock and Stock-Altered 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 ports 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 around 4,000 rpm or at wide open throttle, and if you want the choke plate/shaft installed.

All rebuilt carburetors that we service and sell come with a 30 day workmanship warranty and are guaranteed to be free of defects.

The venturi in these carburetors can be bored so they'll have a 1.2" 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 have been 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 your altitude, you will need to make the final adjustments so the engine will run smooth.

NOTE: These carburetors are designed for use on Stock and Stock-Altered 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 ports 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 around 4,000 rpm or at wide open throttle, and if you want the choke plate/shaft installed.

All rebuilt carburetors that we service and sell come with a 30 day workmanship warranty and are guaranteed to be free of defects.

  • With top high speed fuel adjuster. (For up to 4,000 rpm operation.)
    • Outright. $250.00 each, plus shipping & handling. [When available.] NOTE: Please don't discard your Carter or Kohler carburetor core. These are no longer made and are considered valuable nowadays. If not rebuildable, maybe the parts can be used on a good core.
    • With a rebuildable core trade-in. $225.00 each, plus shipping & handling. [When available.] 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, how the engine will be used and any other parts you may need. And be sure to enclose it in a sealed zip-lock sandwich bag to prevent the gas odor from escaping the package. If the odor of gas can still be smelled from outside the package, then apply perfume or cologne 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.

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, 1604, 1606 and 1806. NOTE: These driveshafts are made to order. When ordering, please specify the model of Cub Cadet you have and possibly the exact length and where you want the roll pin holes drilled. If you're not sure about the length, to determine the exact length, measure between the end of the crankshaft threads or bolt head to the input shaft on the transaxle (or creeper drive input shaft), and then subtract 1/4". This will allow an 1/8" clearance on each end. I also make driveshafts for hydrostatic drive Cub Cadets. Ê

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

3/8" diameter x 1-1/2" long for the OEM 3-pin drive plate and drag link arm. Hardened carbon steel. NOTE: The holes in the drag link arm and spindle may need to be drilled to .375" (3/8") for this pin to fit.

Clutch Drive Plates - | Please contact me if you're interested in any of these parts or services.
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 the 6- or 3-pin drive plate. Replaces Cub Cadet part # 961-3002.
  • $40.00 each, plus shipping & handling.

IMPORTANT - Both pressure plates MUST be resurfaced until perfectly flat and trued-up in a metal lathe or severe clutch slippage may result!

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

  • The fiber material is so hard (for longer wear), it's actually brittle and breaks easily when mishandled.
  • Sometimes when installing engine in tractor, the fiber will chip off when sliding drive studs or pins into clutch disc.
  • The holes in the fiber material will sometimes chip off or wear larger under normal use because the drive studs or pins place pressure against the holes.
  • Using the 6 pin drive plate with a 6 hole clutch disc will place 50% less pressure against each hole, reducing the amount of wear against each hole.


Coming Soon! A-1 Miller's own CNC-machined 6-Hole Aluminum Clutch Discs. Projected price: $15.00 each, plus shipping & handling.

New machined aluminum clutch disc kit 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 disc is turned in my metal lathe and then the holes are precision-drilled using my milling machine in an 8" super spacer with a 6-notch masking plate.

The zinc-plated steel lock washer and steel spacer requires that a stiffer pressure spring, such as the cultivator spring kit, to be used so the lock washer will collapse enough for the clutch to grip better. The lock washer don't work well with Cub Cadet's OEM pressure spring.

IMPORTANT - Both pressure plates MUST be resurfaced perfectly flat and trued-up in a metal lathe or severe clutch slippage may result!

Magneto Ignition Coil for engines with point/condenser ignition. For Kohler K-series flathead cast iron block, most smaller aluminum block Tecumseh and Clinton engines with coil/stator under flywheel. Replaces Tecumseh part # 29632, 30546, 30560, 30560A, 610768, Tecnamotor # 1633.0001, Kohler part # 231718-S; Clinton # 135-13-990 and Phelon # FG-6240. 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 II, Mega-Fire or Kohler modules (see below Ê). 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: 10mm (.393") x 10mm (.393") square center hole (across flats) x 1.620" o.d. x 1.050" length. If laminations on your stator are too big for the center hole in this coil, they can be ground or filed smaller so coil will fit snug, then bend one laminate over to retain coil, and coil should still produce a hot spark. The coil must fit snug on the laminations to receive the full effect of the magnetic field from the magnets to fully energize the coil. How magneto coils produce a spark.

NOVA 2, Mega-Fire and OEM Kohler Electronic Transistorized Solid State Ignition Modules -
  • 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 installed internally or externally, and with coil located 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, one or two cylinder outboard boat motors, etc., with points and condenser ignition. But will not work with most Stihl trimmers and chain saws. 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 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 the NOVA 2 module. 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.

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!)

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!)

Crank Trigger Electronic Ignition Parts and Kits - (The parts listed below Ê may be purchased individually or as a kit.) Top of page | Please contact me if you're interested in any of these parts or services.

NEW and IMPROVED BRIAN MILLER CRANK TRIGGER IGNITION SYSTEM COMING SOON!
Please check back for updates.

Inductive Proximity Sensor. Normally Open / NPN type. Requires 6-36 volts of external power. On models equipped, the LED sensor will illuminate when energized. Durable metal shielded threads with two jam nuts, three wire leads and 10 foot long wires. Dimensions: 15/32" (12mm) diameter x 1-3/8" thread length. Click here for wiring diagrams.
  • $40.00 each, plus shipping & handling.
Magnetic Pickup Coil. Self-generating power. Durable metal shielded threads with two jam nuts, two wire leads and 10 foot long wires. Please specify diameter when ordering. Click here for wiring diagrams.
  • 3/8" diameter x 1" thread length. $60.00 each, plus shipping & handling.
  • 5/8" diameter x 2-1/8" thread length. $60.00 each, plus shipping & handling.

Set the air gap (clearance) between the magnetic pickup coil or inductive proximity sensor and trigger screw (in the disc below Ê) at a minimum of .025" and no more than .25" (1/4") with a brass, plastic or paper (anything non-magnetic) feeler gauge. If the gap is wider than .25", the engine could misfire at high rpms or at wide open throttle due to normal engine vibration. And of course, direct metal contact will damage either unit. If the gap is closer than .025", due to normal engine vibration, the magnetic pickup coil or inductive proximity sensor could strike the trigger screw (or disc) and damage could occur, rendering either one useless. Please contact me if you're interested in any of the above È parts.

Ignition Control Modules:

New Chrysler ignition control module. Requires a minimum 1.2 ohm ballast resistor to prevent from burning up unit. $22.00 each, plus shipping & handling.

  • 1.6 ohm ballast resistor (for Chrysler module above È). $7.00 each, plus shipping & handling.

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. And as far as some parts being no longer available - 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.

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 we sell 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 ordered individually. So please contact me with a list of parts you need, and I'll get back to you with a total 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.

  • Bore and notch Kohler 10hp-18hp cast iron block single cylinder and KT21, M20 and MV20 twin cylinder connecting rods for installation of bearing inserts. $25.00 labor each, plus shipping & handling.
    • NOTE: If a crank journal is worn beyond specs or badly scored/burnt,it will need to be reground 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.
    • FYI - Before I machine a rod for bearing inserts, I use a metal "plug" alignment tool that I made in my metal lathe 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 table of my milling machine and after leaving the big hole centered or moving the table offset for piston pop-out, I securely lock the table so the rod won't move in any direction. But for reasons unknown, sometimes the cutter/reamer will bore the hole in the rod slightly off-center between the bolts or studs. Whenever this happens, I grind away part of each bearing shell so they'll clear the rod bolt. I've talked to other machinist who bore Kohler rods about this and they tell me sometimes the same thing happens with them. But as long as the bearing shells are ground for clearance of the bolt, it poses no problems.
    • NOTE: On the K241/M10 (10hp) Kohler engines, the piston seems to come within .020"± from the top of the block, which lowers the compression ratio. Therefore, when boring the rod for installation of bearing inserts, it'll be a good idea to offset the bore .020" towards the oil dipper (lengthen the rod by .020") so the piston will be more or less flush with the top of the block. And offset the bore .040" for a .020"± piston pop-out.
    • 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 K-series 16hp cast piston or "new style" forged Mahle pistons. $20.00 labor, plus return shipping & handling.

And the lobes on the used cams have not been reground for performance, and we have no 18hp cams available.

Professionally Reground 4,000± RPM Performance Torque Cam for Kohler K-series and Magnum engine models K241/M10 (10hp), K301/M12 (12hp), K321/M14 (14hp), K341/M16 (16hp) and K361 (18hp OHV). This 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 (18hp OHV) cam. This cast cam performs best with reworked and undercut stock size 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, and the engine will not be able to produce as much power. This cam profile helps the engine produce the most power and torque between 3,600-4,500 rpms. At higher rpms, no substantial increase in power will result. 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 work. Use with OEM Kohler 1" base lifters. When reusing lifters, roughen lifter faces with 600 grit sandpaper to produce a new wear pattern and so the lifters will rotate slightly with every lift to prevent wear to the cam lobes. For best performance when pulling, use the medium performance valve springs below Ê with this cam. 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 to OEM specs, and it should be good to go!

FYI: When the cam lobes are reground, metal is removed from the base circle which reduce the diameter of the base circle in order retain maximum lift at the point on the lobe. The ramps on the lobes are also "rounded" to give the cam more duration. The cam grinding machine's grinding stones are about 1" wide, and after the cam grinding process, I have to manually grind metal away from the sides of the base circles so the edge of the lifters won't "ride up" on the 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. 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.

  • Outright: $150.00 each, plus shipping & handling.
  • With core trade-in: $125.00 each, plus shipping & handling.
    • Only the one-piece cam (originally with the automatic compression release) will be accepted as a core. Core must be in good condition, no cracks, never reground or welded on before with gear teeth in good condition, minimal wear on points lobe and preferably the compression release tang intact. When sending a core to me, please include a note with your name, mailing address, phone number and that you want to trade the cam in as a core for the Reground Torque cam. I will then deduct $25.00 from the price of the cam. Please send your core to: A-1 Miller's Performance Enterprises, 1501 W. Old Plank Rd., Columbia, MO 65203-9136 USA.
Hot-Stock and Stock-Altered high-performance Camshaft for Kohler K-series and Magnum engine models K241/M10 (10hp), K301/M12 (12hp), K321/M14 (14hp), K341/M16 (16hp) and K361 (18hp OHV) Pulling Engines. This is a much more aggressive camshaft than above. 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 (290°). This cam profile performs best with 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, there is a distinctive "BOOM, BOOM" exhaust sound upon deceleration and at idling speed with this cam. 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. For best performance, use a set of the high-performance Hot Stock/Stock-Altered valve springs below Ê with this cam. Can be used with OEM Kohler 1" base lifters. When reusing lifters, roughen lifter faces with 600 grit sandpaper to produce a new wear pattern and so the lifters will rotate slightly with every lift to prevent wear to the cam lobes. 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 to OEM specs, and it should be good to go!
  • Outright: $200.00 each, plus shipping & handling.
  • With core trade-in: $175.00 each, plus shipping & handling.
    • Only the one-piece cam (originally with automatic compression release) will be accepted as a core. Older, out-dated steel cams for Kohler flatheads will be accepted, too. Core must be in good condition, no cracks, never reground or welded on before with gear teeth in good condition, minimal wear on points lobe and preferably the compression release tang intact. If core has a worn lobe, but the rest of the cam is in good condition, that would be fine because it will need to be welded up (and then reground) anyway. When sending a core to me, please include a note with your name, mailing address, phone number and that you want to trade the cam in as a core for the Reground Torque cam. I will then deduct $25.00 from the price of the cam. Please send your core to: A-1 Miller's Performance Enterprises, 1501 W. Old Plank Rd., Columbia, MO 65203-9136 USA.

Reconditioned OEM Crankshafts, Balance Gears and New Main Bearings - | Please contact me if you're interested in any of these parts or services.
Reconditioned OEM Kohler Crankshafts - [When available.]

Available for Kohler engine models K241/M10 (10hp), K301/M12 (12hp), K321/M14 (14hp), K341/M16 (16hp) or K361 (18hp OHV). 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" long keyed PTO shaft. 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'd probably have just as good a 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 know your engine's exact model and specification numbers, go to kohlerplus.com (requires Microsoft Internet Explorer), to find the correct part number for the crankshaft, and then find the dimensions and specifications of the crankshaft is here: CRANKSHAFT REFERENCE MANUAL.

  • OEM Kohler part. $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 then 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 and 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.
If two 5/16" bolt holes needs to be made in the exhaust port for installing the 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 to drill the holes precisely in the exact locations. The holes are to be drilled with a 17/64" or letter "F" drill bit, at about 1-1/4" depth. Then the threads can be cut perpendicular to the exhaust flange with a (preferably new) 5/16-18 NC tapered tap. Use thread cutting oil and go slow when cutting threads in cast iron to prevent from breaking the tap off in the block. Because if it breaks off, it'll be extremely hard to remove! (It'll be the beginning of a nightmare!)

A-1 Miller's Repair Service: Professionally drill and tap two 5/16"-18 NC holes in the exhaust port for your block to install exhaust header pipe below Ê. $40.00 labor, plus return shipping & handling.

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. We 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, and 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, we will need your crankshaft and connecting rod(s).
    • 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.

  • Bore and notch Kohler 10hp-18hp cast iron block single cylinder and KT21, M20 and MV20 twin cylinder connecting rods for installation of bearing inserts. $25.00 labor each, plus shipping & handling.
    • NOTE: If a crank journal is worn beyond specs or badly scored/burnt,it will need to be reground 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.
    • FYI - Before I machine a rod for bearing inserts, I use a metal "plug" alignment tool that I made in my metal lathe 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 table of my milling machine and after leaving the big hole centered or moving the table offset for piston pop-out, I securely lock the table so the rod won't move in any direction. But for reasons unknown, sometimes the cutter/reamer will bore the hole in the rod slightly off-center between the bolts or studs. Whenever this happens, I grind away part of each bearing shell so they'll clear the rod bolt. I've talked to other machinist who bore Kohler rods about this and they tell me sometimes the same thing happens with them. But as long as the bearing shells are ground for clearance of the bolt, it poses no problems.
    • NOTE: On the K241/M10 (10hp) Kohler engines, the piston seems to come within .020"± from the top of the block, which lowers the compression ratio. Therefore, when boring the rod for installation of bearing inserts, it'll be a good idea to offset the bore .020" towards the oil dipper (lengthen the rod by .020") so the piston will be more or less flush with the top of the block. And offset the bore .040" for a .020"± piston pop-out..
    • 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 K-series 16hp cast piston or "new style" forged Mahle pistons. $20.00 labor, plus return shipping & handling.

  • The K241/M10 blocks have a STD cylinder bore of 3.250" and the stroke is 2.875". All of these blocks have an exhaust valve diameter of 1.125" and the intake is 1.375". Some rare K241 blocks have "K301" embossed on the PTO end. These have a thicker cylinder wall than ordinary K241 blocks.
  • The K301/M12 blocks have a STD cylinder bore of 3.375" and the stroke is 3.250". There are no other major differences between these two blocks. These blocks have the same size valves, and most external parts will interchange. Due to the smaller cubic inch displacement, which lessens the amount of air that enters the engine, theses engines use a Carter or Kohler #26, or Walbro #52 (1.07" throttle bore) carburetor.
  • The K321/M14 blocks have a STD cylinder bore of 3.500' and the stroke is 3.250". There are no other major differences between the K241/M10, K301/M12 or K321/M14 engines. The early K321 blocks have an exhaust valve diameter of 1.125", and the valves in the later K321 blocks are the same diameter, which is 1.375". Some internal, but most external parts on the K241/M10, K301/M12 and K321/M14 engines will interchange, with the exception of the early style K241 cylinder head and size of the carburetor. Due to the larger cubic inch displacement, which increases the amount of air that enters the engine, the K321/M14 engines use either a larger Carter or Kohler #28 or #30, or Walbro #60 (1.17" or 1.2" throttle bore) carburetor.
  • The K341/M16 blocks have a STD cylinder bore of 3.750" and the stroke is 3.250". There are no other major differences between the K241/M10, K301/M12 or K321/M14 and K341/M16 engines, except the valves are the same diameter, 1.375" and the K341/M16 blocks have 10 cylinder head bolts. Due to the larger cubic inch displacement, which increases the amount of air that enters the engine, the K341/M16 engines also use a #30 (1.2" throttle bore) carburetor. And most external parts, except the cylinder head and air shields, will interchange with the K241/M10, K301/M12 or K321/M14 and K341/M16 engines.

There are many other variations between the Kohler K241/M10, K301/M12, K321/M14 and K341/M16 blocks. 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 (for a Cub Cadet or John Deere oil pan).
  • The very early K241 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 the holes can be drilled and tapped.)
  • Some blocks have the oil dipstick tube hole next to the cylinder, above the crankcase, while others have no hole present. The hole is either drilled or threaded. 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.
  • 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.
  • The threaded holes on the PTO end of the block can have different bolt patterns.
  • 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 rebuild engines from ordinary stock up to 4,000 rpm governored pulling engines. I can 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. If you wish to have me rebuild or build-up your engine, I'll need a list of 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. I'll build your engine to the limit according to the rules, not less than what the rules allow. 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 I couldn't repair!

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!

All pulling engine builds are strictly confidential. This means your pulling competition will not know what goes into your engine!

IMPORTANT!

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

For proper break-in of a new or freshly rebuilt engine, use conventional (petroleum-based) SAE 30 weight motor oil containing an 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 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. Then drain the oil while it's hot, and either continue to use conventional (petroleum-based) SAE 30 oil, or switch to a quality 20W50 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. 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.

below Ê are details and prices to rebuild your engine - 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 and then mail customer's parts at my local Post Office, etc., it may take me several months, possibly up to 6 months to rebuild an engine. I also have to depend on other local machine shops to balance engine parts, 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. - Brian Miller

Competitive Pulling Engine Refreshing Service Ê 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 refreshing job. This service is for engines that have been previously rebuild or built for pulling, and needs the basic parts to revive the power. It is not a complete rebuild.

And I don't offer any chrome-plated sheet metal because the chrome plating process is cost-prohibited.

NOTES:

IMPORTANT! If you decide to ship your engine to us, please enclose it in a sturdy wooden crate with cushioning surrounding the engine, and then fasten or strap it securely onto a wooden pallet. Do not use a cardboard box alone! To build a crate, start with 2" x 2" frame work with a skid pallet on the bottom (so a forklift can pick it up without damage), fasten the oil pan of the engine to the bottom of the crate (pallet), use either 1/4" plywood or paneling to cover the crate, place some heavy pieces of Styrofoam or folded cardboard around and above the engine to help cushion it during transport, and fasten everything on and in the crate with sheet rock screws. Or if you bring an engine to me in person, sit it in an automotive tire to keep it from moving around during transportation. And please let me know first so we can expect your arrival. It'll be best to have everything on the engine that can wear so we can repair them too, and make the necessary adjustments.

To ship your engine to us, first off, do not use the US Mail Service, UPS or FedEx Express! We and our customers have had too many problems with them in the past. They wouldn't even make good on the insurance either. Their gorillas (employees) are trained in handling lightweight packages (weighing up to 70 lb.) and the heavier items tend to get damaged with their kind of handling. 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.

If you decide to ship your engine to me, please crate it well. We're authorized FedEx Ground (for anything up to 150 lbs.) and FedEx Freight (for anything over 150 lbs.) shippers because they've been proven to be the lowest cost, most gentle and reliable shipping companies. Here's a great web site that calculates freight charges. Go here: http://www.shipgooder.com/ and type in your zip code, our zip code (65203-9136) and the crated weight of a typical complete 10-16hp Kohler engine (145 lb.). Shipgooder doesn't ship anything. It's web site just lets you see the latest cost of various shipping companies. Contact your local FedEx Ground for more details and to schedule a pickup. Or you can use a major trucking company with a good reputation for shipping heavy, fragile objects. Look in the Yellow Pages and ask around. The reason we say this is because we once returned a rebuilt engine that was crated very well to a customer using a well-known shipping company, and it was almost destroyed in shipping when he received it. You'll have better success with shippers such as FedEx Ground, FedEx Freight, Roadway, etc. Freight company employees are trained in handling heavy packages plus they use tow motors to move the freight around, not like UPS or FedEx Express with their uncaring "gorillas" unloading and loading the trucks. The approximate shipping weight of a crated 7 and 8hp Kohler engine is 100 lbs. And 10-16hp single cylinder cast iron Kohler engine is 145 lbs.

To ship an engine, freight companies require it to be in an enclosed wooden or sturdy plastic crate. It's best to securely fasten it with the oil pan bolts on a pallet made of 2 x 4's and fasten the boards together with long drywall screws, not nails. Then place a 2 x 2 wooden frame around the pallet and fasten 1/4" plywood with a 2 x 2 frame work. Run cross-braces which encompasses the top portion of the cylinder of the block. This will support or stabilize the top of the block and keep the engine from getting ripped off the base. Put a lid on the top and then load it in the trucking company's truck when it arrives with a tow motor. You shouldn't have any problems shipping an engine this way.

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

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

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

Heavy duty ball joint end (Heim joint). Has a 3/8-24 NF right-hand female threaded hole and a 3/8" i.d. hole. Extremely strong!

And these do not come with a dust/dirt seal, 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, applying chassis lube (grease) to the balls in the Heim joints would help them operate smoother and last longer.

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

  • 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.
