I have an 85 Brat with a new coil,plugs,wires,cap&rotor,battery,alternator,and fuel pump...I just recently re-built the carb for the first time ever and thought i did a decent job. However, when I try to start it, it turns right over, but the engine wobbles a lot and it will only stay running with my foot down at least half-way on the pedal... Could this be my carb or perhaps even my distributor? please help
