I just finished my first build. An 80cc (I know it's only like 66, but whatever) boygofast kit.
The thing starts right up without the choke on and it seems to run ok although I'm not trying to push it because I want to follow the break in period. There seems to be two problems however...
1) I cannot get the thing to idle correctly, even with the idle screw all the way in.
2) There seems to be a dark almost oil like substance coming out of the muffler.
I tried to seal the connection between the carb and motor as best I could, I think I might have an air leak somewhere else though. Could an air leak cause those problems? If so, where could it be?
thanks in advance.
ps i can get some pics of the bike if needed...
