During this winter, I started the bike let it idle for about 2 minutes, went into the house, came back out and the bike was dead. Wouldn't start at all. I've taken the bike apart, petcock is delivering fuel, fuel goes into the carb, but doesn't fill the bowl. I've completely removed the floats and as far as I know it should dump fuel out of the bottom with them removed. The fuel is going into the carb through the brass fitting, but that's where it stops. What would cause this and how would I fix? Checklist: New fuel Clean plug Cleaned all jets, and bowl. Also, if anyone has a diagram of the carb I would greatly appreciate it.
