u/An-Rend

I have an 86 Honda fourtrax. Was running great before it sat for awhile. The friend I got it from thought he’d be helpful and replace the carb with an aftermarket one. I know the OEM is best and I have it.

Idles great. 1 gear has all the usual power.

When you first get on it. First gear great, second gear great, 3rd gear top end power starts to fail, 4th gear bogs out.

After that 1st gear still works fine 2, 3, and 4th bogs out.

Any ideas?
