I'm having a problem with the pick up of the car. I have rebuilt the carb, flushed the oil to try to clear any blocked passage ways. I don't know much about the car, or the engine. When normal driving it seems to do well, but when I press the gas it seems to putt out. It doesn,t do it all the time , but I haven,t figured it out yet. It just started maybe a couple of weeks ago. Today I,m going to tune the car up and change the one pipe to a dual system. please help me put this beauty back one the road.
