i've had the carbs rebuilt, timing belts and ingnition pulse coil assembly replaced. Had the carbs looked at by a different tech. after the rebuild. Having issues with what seems to be a sticking float like symptom. Very sporadic. Some times works fine, especially when i bring it to a mechanic. Other times it wont get out of its own way. Low power at hwy speeds, sometimes the smell of gas. Poor gas millage. Anyone have these issues out there before?
