About 2 years ago I had the carburetor rebuilt on my 51 Champion and it worked great up untill about 2 months ago. Now when I push on the go pedal it just falls on its face. Somtimes it even dies and then it is very hard to start. It will idle all day long and never miss a lick. I have two new fuel filters, one before the pump and one before the carb. I assume it is the accelerator pump but I dont know much about these carbs. Infact I dont know where the pump is on these carbs. Does anybody have a diagram? Any suggestions
