Default Timing
For the engine builders what is a good timing mark to run a k321 at or a ballpark and is 22 degrees to much?

What is your top end RPM? What fuel?

IIRC, 20° is the stock setting so, 22° is probably a good place to start. Timing depends on a lot of things. You have to play with it.... it's like tuning a carb.

Don or Austin would be better to answer, hopefully they will come along.

Since it's an open RPM motor, I would say that 22° may not be near enough timing. I would think more along the lines of 25/26°.

timing depends on a few things, what type of ignition, plug location, number of plugs, stock or billet head, chamber design, compression ratio, carb size, fuel. I've run everything from 20 to 35 degrees ,

Just my 2 cents but if your building a puller engine dvogtvpe is the master. Listen to his advice and consider it to be like going to school.

Don might feel differently but, I think you are wasting your money buying 110 fuel. Can you tell us more about the engine internals? Cam spec, bore, how much was removed from the head?

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.
