When my 1969 Z/28 was idling poorly and almost stalling at a stop sign or red light my mechanic, in addition to other things he did to the carb, made the vacuum advance inoperative. The car has run fine and no longer has the decreased idle or stalling at a stop.

I hooked up the vacuum advance. I had to turn the idle down because of the extra timing. It seems to run pretty good. I do have to shoot a little extra fuel in to get it to start.
