I've read over and over on many different posts about air leaks in your carb or having the wrong carb adjustments making the engine run lean can cause overheating.
The dumb question is, if the tractor seems to be running great, how do you know if it is running lean? ![]()

Pull the spark plug and post a pic of it. Obviously the pic you post need to be of the end that goes in the engine.

Adjust it until it blows smoke on a quick rev, then back it off just a little. Rich is better than lean on an air cooled motor. Obviously, you don't want it so rich it carbons the combustion chamber with coal black soot... but it needs to be on the rich side.

See, sometimes you just overlook the obvious. I'll pull the spark plug and post a pic of the end that goes into the engine.

Thanks, that's what I want. It really runs great for 1 3/4 hours solid. Then acts like it's starving for fuel. I've been tweaking a new carburetor.

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.
