Default Can't get motor to run right.
Well I got my K241 (10HP) kohler in my 71 with everything hooked up and got it started, but I am unable to get the carburator adjusted right. I took it all apart soaked it in carb cleaner, blew everything out with air put it back on and still no luck. The motor runs but it backfires a lot and "skips" but still runs fine. The muffler that I got with it is all rotted out so it is bacically straight through. Is is possible that the empy muffler is the reason for my troubles, and if so I really don't want to spen the money on a new one, so would a small stack backfire also or could I just readjust the carb to the stack and it run smooth?

The muffler shouldn't cause that kind of issue. Have you replaced the points and condenser?

I got a K321 running and it ran like you described.

The condenser wire was disconnected.

It had a pretty blue spark without the condenser.

1) Carb-- Did you feel for air coming out all the passages? I use a carb cleaner to spray and look for liquid coming out each passage.

http://onlycubcadets.net/forum/showt...=carb+settings
post 2 has the correct carb settings for the needles

2) points-- verify .020 gap or better yet, use a timing light to set them. Also make sure they are CLEAN

Double check wiring and connections.

Just a thought. Make sure the condenser is on the negitve post. It will run on the positive but with symptoms as you discribed.

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.
