I've been having trouble getting the carb to fit on this bike so I've gone through a few different extensions and bent intakes to get it to fit. I finally found one that works after some persuasion with a propane torch and a pipe wrench. Anyways there was a small leak where the exhaust clamps to the carb and i had to wait a couple weeks to get an o-ring to stop it. In that time it ran well and would start on the second or third pedal (I have a shift kit). I put the o-ring in and now it won't start. I've got it on the leanest c-clip setting right now and have tried all the others. I can sometimes get it to start for 30 seconds or so with a high idle and as son as i try to adjust the idle lower it dies. I'm completely stuck at this point.
