Default K341 will not start

I have a Kohler K341 in a Cub Cadet 149, I rebuilt the engine last spring (‘17) and it ran well all summer. It last ran in late October, and in early December I tried starting it to clear snow with no luck. It seems to turn over ok, but I am getting exhaust out the carb. I tried removing the muffler with no change, and removed the valve cover and checked the valve clearance.

Any suggestions would be appreciated.

What does the bold mean?? Makes no sense.


Engine like that only takes 3 things to run. Fuel, air and fire. Which one isn't it getting?

I fixed it. It was supposed to say ‘exhaust out the carb’.

Well, what would cause exhaust out the carb?

That was my thought, which is why I pulled the valve cover, and the valve was following the lifter with the appropriate gap when closed.

I guess the next step is to pull the head and check it from above.

Give the timing a check, it is possible that somehow it is very advanced, firing while the intake is open, thus belching out the carb.

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.
