To any body that may be listening. I just picked up a 2005 John Deere Buck 500 with Rotax Engine with only 105 miles, and six hrs. It had a rough idle, or more like a miss or a cough every 4 to 5 seconds that would make it stall. Drained the old gas, new gas and treatment, clean the carb.
And still get the cough at idle, and back fires when you kill the ignition ...runs fine when your driving it. Any Help??

I'll check throttle cable. and carb looked pretty clean. have it off now for good cleaning. Could timing or valves be an issue with such low hours?

Those engines are pretty solid and a push rod design generally haven't heard much of them being out of time unless you have reasons for it to be out???

No reason for vales or timing to be out. There is an electrical element on the bottom of the carb. Could be carb heater??? could this be an issue?
