I have an old 125 atc honda 3 wheeler that has been sitting in my shed for 14 years. I recently got it out to see if i could revive it. Cleaned carburetor and installed new gasket kit also in installed new gas tank. I got it cranked but it won't idle on its own. Any ideas would be appreciated.

 

Welcome to the forum. I know you said you cleaned the carb. but after sitting that long maybe at least get a new pilot jet only about $5.00 from the dealership. Also if it only runs on choke that usually means a clogged idle jet. Other than that try unscrewing the cable out a little from the thumb throttle if that's not enought or if it can't be adjusted there try unscrewing it a little from the top of the carb. that should get you close then you can tweak it with the idle adjust screw.
