Default 126 Running Rough
I don't know much about motors, so I'm sorry in advance if anything I say does not make sense.

My 126 runs kind of rough. Like small backfires. It is the worst coming down hill, but it does it at other times too. i don't believe it does at idle, at least not like at higher throttle.

Any suggestions what I could try to fix this, adjustments or tests?

Could be running lean..... Poor fuel flow, dirty carburetor, carburetor out of adjustment are some of what causes lean conditions. Does your tractor run better with the choke closed somewhat?

Yes, I meant to say I have to leave the choke closed about 1/4 of the way until it warms up, I haven't tried leaving it closed after its warm though.

I adjusted the carburetor and it seems to be running much better now. Should I still clean it anyway, or leave it alone since its running fine now?

If it ain't broke, don't fix it.

a little Seafoam in the fuel goes a long ways to avoiding carb issues

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.
