Bought a 94 serow , had been standing for a while, was running lean, noticed inlet manifold was perished. Changed that and the o ring. The guy had a piece of foam as an air filter, so put in proper foam element. Changed plug for correct one. But still seems to be running rough on full throttle. Dies if you crack open throttle from idle, ok if you do it slowly. What s worth checking in the carb. Could diaphragm be perished? Any help great fully accepted.
