my71 has been sitting for a while and is need of some carb attention. I was thinking of changing to a Holley 750. Should I use mechanical or vacuum secondaries? It has a 750 carter in place now. Or would you recommend something different?
personally i would rebuild the carb you have now, the carter carb is easy to tune. if you are set on getting a holley though, i would get a vacuum secondary carb for the street.
About the only tough thing to recondition on a carb is if the throttle shaft has worn the shaft bore too big. In this case, professional carb rebuilders can sleeve these easily.
true enough. between a friend of mine and i we have 7 edelbrock 1406's, and all but one runs great, and that one is more than 10 years old now and ready for a rebuild.
