my motobecane bogs down at full throttle sometimes. i cleaned the carb and i dont have a pepcock (sp). my fuel line is clean and its not pinched anywhere. it was leaking fuel but i fixed the float and its fine now. i dont know what else it could be. please help. im also running a 12v light in the front headlight and it should be a 6v. when i use the brakes the headlight goes out, is there any way to fix this other then getting a 6v light which ive looked everywhere for when the original burnt out.
