The stop pin is what keeps the governor gear on the stub shaft. Once the gear is in place, the stop pin (nothing more than a screw with a long skinny end) is screwed into the threaded hole beside the governor shaft bushing and the protruding end crosses in front of the gear and keeps it from coming off the stub shaft.

If you are able to slide your gear back and forth significantly then it is possible your stop pin is broken. You may need to remove it and look at the end and see if it has broken off.

alright...



maybe you can help me understand one last thing before I tear this entire engine apart...

i understand the procedure for setting the governor arm and xshaft..

i understand the basic function of the governor gear and how it works..

what I do not understand, is how I set the maximum engine speed.

Does the governor just automatically know to limit at 3600? because mine isnt...

im just a little lost with this entire thing.

You need to buy a tachometer for a single cylinder engine to set your RPM's correctly.
To set the high rpm governor speed, place one end of the governor spring in the middle to lower hole in the "L" shaped governor lever, and place the other end of the spring in either the top or second hole from the top in the short lever that's located under the carburetor or on the flywheel shroud. (Follow the Kohler Service manual for this step.) It's best to use a small engine tachometer to determine the exact rpm to prevent over-revving of the engine, which could cause the connecting rod to break. The high speed governor limit for a stock engine is set at 3,600 rpm

I am going to purchase one of these when I get my 128 finished and am ready to start the motor.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
