Is this true? A member of another forum that I am part of said something about the carb being advanced enought to adjust for the engine it was atop of. Something about the weighted flap on top or something. I've been unsuccessful in getting a reponce from him since. Anyway, is there any truth to that and if not other than trial and error how would I go about getting the correct jets to "jet it down." Also, did these engines ever have a four barrel offered in 1966? Is so could I jet go get those jets? | | |
