Mine only has 9000 miles on it. I Idle on high but everyting else is a fail. On mine with so much testing, dunking in part cleaner. full dissassembly/ rebuild. untrasonic cleaner. everything.... and same problem.

i believe i have a vaccume leak somewhere. that would mess with the mixture going into the carb or lack there of. if you can get it to idle low ish, and spray some sea foam, or hell carosene gas (NOT LIT) around your hoses and connectors, and notice an RPM spike BOOM theres your vac leak. where i suspect mine is a lil tricky. i think its between the carbs on the O rings. This way you have something else to test instead of repeat continuouse cleaning over and over again.
