So then i was thinking that i might be running to lean so i put a different carb on and it did the same thing at this point i am not sure what it might be so if somebody might have any suggestions please send them my way.Iknow this is just a brief description but if you have a question please contact me thanks Jeff.
have you adj. the valves? the next thing i would do is check the comp. with a gauge and get a vac. reading.
