Default K321a has me stumped

I removed the engine and gave it a cleaning with brake parts cleaner on the ouside. I also removed the cylinder head and removed the carbon build up. The valves are working, and the seats look good. The bore is standard, and there is no obvious scuffing or hot spots on the cylinder walls.

I also changed the points and condensor. I did the static timing technique, and the points are breaking perfectly when the "SP" mark is showing.

I have spark at the plug and the carb is supplying fuel/air.

The motor turns over, but will not start. I also noticed that the ground wire on the voltage regulator is getting very hot when I crank the engine.

Any ideas?

Do you have a good ground from the battery to the chassis and from the chassis to the engine?? My K301 tried grounding through the throttle cable a couple of weeks ago. Found out when I tried rotating the engine by hand. Gonna be a nice scare when it finishes healing.

Mine did that. Turned out to be a short in SG. Did crank it, but drew all the amperage, insufficient spark.

If you have a spare SG, bolt it on and try it.

Is the ground wire getting hot on the voltage regulator a symptom of a larger problem or am I just cranking it too long?

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.
