High Torque Gear Starter Motors for Kohler engine models K141, K161 and K181 single cylinder cast iron block Kohler engine. 12 volt, 16 tooth gear. All starter motors are high torque nowadays. They have 20% more wire windings than the early OEM Kohler starter, giving it 20% more cranking power. Draws less amps; a smaller battery can be used. Cranks engine about twice as fast and draws less amps than an ordinary starter. But with a broken compression release, a direct-drive high torque starter may not be able to crank the engine. It'll be best to adjust the valve clearances, repair the compression release mechanism or replace the cam with a working compression release. FYI - The aftermarket starter motors I sell are the same as OEM Kohler starters. Kohler just place a big markup on theirs because it comes in a Kohler brand box and the starter has the Kohler name stamped on it. Kohler part # 41 098 08-S.
  • New high quality aftermarket starter. Comes with manufacturer's 100% unconditional limited one year warranty. Replaces Kohler part # 41 098 08-S. $90.00 each, plus shipping & handling.
  • New OEM Kohler starter. Comes with a limited 90 day warranty against defects in materials or workmanship. OEM Kohler part # 41 098 08-S. $190.00 each, plus shipping & handling.

IMPORTANT! Most quality-made starter motors are designed to last the life of the engine. Therefore, if a good starter burns up prematurely, then this means that it has cranked the engine for too long at one time. All starters are actually 6 volt motors operating on 12 volts. This is what gives them so much torque to crank the engine so fast and with ease. So if a starter motor is spun too long (longer than 2 minutes), the excess voltage will burn up the wire windings in the starter. The longer it's spun, the hotter it will get, which causes the windings to get very hot, which causes the insulating/separating varnish coating on the windings to melt. When the coating melts, the windings make contact with each other and become shorted out, and you have a burned up starter on your hands. That's why most owner's and repair manuals say to never crank an engine longer than 2 minutes at a time without allowing adequate time for the starter to cool before cranking it again. (If an engine won't start within 2 minutes of cranking, then it obviously needs a major tune-up or repair!)

Replacement Starter Gear Kit for Kohler Engine Models K241-K361 with the High Torque Gear Starter (below). Fits the newer upper and lower mount gear starters with the 10 tooth gear. Will not fit the older low torque gear starters.
  • High quality aftermarket. Replaces Kohler part # 41 755 33-S. $33.00 each, plus shipping & handling.
  • OEM Kohler part # 41 755 33-S. $161.55 each, plus shipping & handling.
10 and 13 Tooth Upper Mount (mounting bolts are below starter) High Torque Gear Starter Motors for Kohler K-series engine models K241, K301, K321, K341 and K361. 12 volt. All new starter motors are high torque nowadays. They have 20% more wire windings than the early OEM Kohler starter, giving it 20% more cranking power. Cranks engine about twice as fast and draws less amps than an ordinary starter. Therefore, a smaller battery can be used. In addition to the extra windings, the 10 tooth starter gear gives this starter extra torque so it'll crank the engine with less effort. The 10 tooth starter provides 13% more cranking torque than the 13 tooth starter, and the 13 tooth starter cranks the engine over 30% faster than the 10 tooth starter. The 13 tooth starter is best to be used with working compression release. But with a broken compression release, a direct-drive high torque starter may not be able to crank the engine. It'll be best to adjust the valve clearances, repair the compression release mechanism or replace the cam with a working compression release. FYI - The 10 tooth starter cannot be used in place of the 13 tooth starter, but the 13 tooth starter can be used in place of the 10 tooth starter by shimming/spacing the starter away from the engine block with an ordinary flat washer on each mounting bolt.

IMPORTANT! Most quality-made starter motors are designed to last the life of the engine. Therefore, if a good starter burns up prematurely, then this means that it has cranked the engine for too long at one time. All starters are actually 6 volt motors operating on 12 volts. This is what gives them so much torque to crank the engine so fast and with ease. So if a starter motor is spun too long (longer than 2 minutes), the excess voltage will burn up the wire windings in the starter. The longer it's spun, the hotter it will get, which causes the windings to get very hot, which causes the insulating/separating varnish coating on the windings to melt. When the coating melts, the windings make contact with each other and become shorted out, and you have a burned up starter on your hands. That's why most owner's and repair manuals say to never crank an engine longer than 2 minutes at a time without allowing adequate time for the starter to cool before cranking it again. (If an engine won't start within 2 minutes of cranking, then it obviously needs a major tune-up or repair!)

High Torque Lower Mount (mounting bolts are above starter) Gear Starter Motors for Kohler engine models K241, K301, K321, K341 and K361 engines. 12 volt. All new starter motors are high torque nowadays. They have 20% more wire windings than the early OEM Kohler starter, giving it 20% more cranking power. Draws less amps; a smaller battery can be used. Cranks engine about twice as fast and draws less amps than an ordinary starter. In addition to the extra windings, the 10 tooth starter gear gives this starter extra torque so it'll crank the engine with less effort. But with a broken compression release, a direct-drive high torque starter may not be able to crank the engine.

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

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

Two Wire Rectifier Diodes. The 3- and 4-amp diodes can be used in a non-regulated small engine alternator/stator12 volt charging system to convert alternating current (AC) to direct current (DC) to recharge the battery and/or to power low-amperage DC electrical accessories, such as LED lights, small electric motors, etc. A diode is not required for filament light bulbs, fluorescent and LED shop lights, and/or an electric PTO clutch. Do not overload the amperage of the diode or it may burn up. The 1 amp diode can be used on an engine with a small charging coil next to the magneto ignition coil on the stator to energize the field windings in a direct-drive 120/240 volt AC portable generator powered by a small engine or for a belt-driven automotive alternator that's powered by a small engine so the alternator/generator will produce electricity as soon as the engine starts. IMPORTANT - Install the diode with the silver stripe toward the generator's field windings.

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

If the charging system continues to generate full charge with no gradual moving back of the needle to zero on an analog ammeter/amp gauge (if installed) while the engine is running, the excessive overcharging may eventually burn out the primary windings in the ignition coil, burn up the electronic ignition control module (crank trigger), burn up the battery, burn out light bulbs, electric PTO clutch, and any other electrical accessories. The solid state electronic voltage rectifier/regulators shown works the same. These voltage rectifier/regulators are small, compact and have the same mounting hole spacing, and fit many 8 thru 24hp Kohler engine models with a 15 amp or 20 amp output alternator/stator charging stator under the flywheel. Each mounts in the rectangular hole in the Kohler flywheel shroud with ribs facing the flywheel for better cooling of the unit. If it's mounted elsewhere with no cool air blowing over it, it could burn up prematurely. These will also work with virtually any 15 or 20 amp garden tractor, motorcycle, etc.alternator/stator charging system. Orientation of the terminals are "three in a row" (AC - BAT+ - AC). NOTE: These cannot be substituted for use with the starter/generator charging system.

Solid State Electronic Voltage Rectifier/Regulator for Old-Style 10 Amp 12 Volt Alternator/Stator Charging Stators below Ê. If the charging system continues to generate full charge with no gradual moving back of the needle to zero on an analog ammeter/amp gauge (if installed) while the engine is running, the excessive overcharging may eventually burn out the primary windings in the ignition coil, burn up the electronic ignition control module (crank trigger), burn up the battery, burn out light bulbs, electric PTO clutch, and any other electrical accessories. These will also work with virtually any 15 or 20 amp small engine alternator/stator charging system. Orientation of the terminals are "three in a row" (AC | BAT+ | AC). NOTE: Cannot be substituted for use with the starter/generator charging system. FYI: After many years of use and for reasons unknown (even to me), the old-style 10 amp charging system is notorious for generating very few amps, about 3 amps more or less maximum at full governed engine speed, and I have no idea why. I believe this is why the 10 amp stator was a short-lived item that was discontinued from Kohler and replaced with the more reliable 15/20 amp stator charging system, which works much better and is still in use on many makes and models of small engines today. So if your engine has the 10 amp charging system and it only generates a few amps, it may need to be upgraded with the new-style 15/20 charging system.

Old-Style 10 Amp 12 Volt Alternator Charging Stator w/Electronic Ignition Energizing Coil. Can be used with Kohler Breakerless, Tecumseh Solid State, or Points/Condenser Ignition. This stator requires a flywheel with charging magnets embedded in an aluminum ring. Use with 10 amp solid state electronic voltage rectifier/regulator (above) to recharge battery while powering electrical accessories. To be used with a Kohler or Tecumseh flywheel designed for a John Deere garden tractor. Fits John Deere garden tractors with a cast iron block Tecumseh engine model VH80, VH100, HH80, HH100, HH120, OH140, OH150, OH160 and OH180 with solid state ignition, and used on Kohler engine models K241 w/specification #'s 46593 and 46608; K301 w/specification #'s 47148, 47175, 47399 and 47419; K321 w/specification #'s 60102, 60118, 60136 and 60136A with Breakerless Ignition.

The wire that connects from the stator to the Kohler Breakerless Ignition Trigger Module or Tecumseh Solid State Ignition Module generates about 250 volts (seriously; I tested it) while the engine is running at full governored speed. Do not touch this wire (terminal) with one bare hand and the engine itself with your other hand while the engine is running! It is not needed for battery ignition or any of my crank trigger ignition systems. So snip off this wire or tape up the terminal to prevent a short circuit or electrocution!

A-1 Miller's Computerized Stuska Water Brake Engine Dynamometer (Dyno) Service with DPM Data Logger Software to Test Horsepower and Torque! | [Top of Page]

For performance testing of 10-16hp single cylinder Kohler stock or competition pulling engines at speeds up to 12,000 RPM. 100% accurate, customers can rent dyno time, fine tune and make adjustments or changes to their engines to gain maximum horsepower and torque, and print-out the results so their tractor(s) will be truly competitive on the track. With an engine dyno, the puller can adjust their engine to get maximum horsepower and torque, and gear their tractor appropriately to have an advantage over the competition. NOTE: A fresh-built engine may not produce full power until it's broke-in. This is when the valves wear-in with the seats to completely seal in the compression. The rings will likely hold the compression, but the valves may leak slightly until they wear into the seats. This is normal for all engines and may take several hours or pulls to happen, then the valves will be able to hold full compression. Lots of pullers tell A-1 Miller's after I've built their engines that it seems to pull stronger every time they pull it.

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


Coming Soon - Detailed Illustrated Plans on How to Construct a Professional Pull-Back and Self-Propelled Garden Tractor Pulling Sled. FYI - The professionally-built self-propelled pulling sled is the only one I've ever built (click the picture to the right to see a larger image of this sled), and I got it right the first time, with very few changes or modifications that had to be made to it. I guess I'm just one of those kind of guys that knows what he's doing. Pullers really like pulling our sled, too. They say it's the best sled they've ever pulled. (Not bragging, just stating a fact.) By the way - Track Master sled is engineered so well (by Brian Miller), that other sled builders/owners have copied my well thought-out and proven design. And I do appreciate them acknowledging my intelligence. Anyway, I have lots of work to do in my shop and I work on the sled plans in my spare time. As soon as my plans with an inventory list of parts to use are perfected, I'll post the update in my websites with the prices of the plans. Remember - Perfection takes time. If it's worth having, it's worth waiting for. Also, I plan to acquire a bigger shop and may build high quality garden tractor pulling sleds in the future to offer for sale. Please call 573-256-0313 (shop) or 573-881-7229 (cell; text or voice message), or email pullingtractor@aol.com if interested. - Brian Miller
