Thank you Inertia, Ok just worked on this Holley, started with fuel level adjustment, then set idle, next moved on to the air fuel adjustment, before I touched the adjustment screws I just wanted to see where they where, as I turned them in they only moved about 1/2 turn on both of them till they stopped, I thought this maybe my problem, because they tell you to turn the air fuel screws in to stop and turn out 1-1/2 so that is where I started at, adjusted both side air fuel screws in to stop and out 1-1/2 turns , started car ran very poorly , I then did a 1/4 turn out got worst, I had a vacuum gauge hooked up trying to get the max. inches of vacuum, the best I could get was 15 inches of vac. and to get that I had the screws turned just about where I started at, only less then 1/2 turn from being fully seated, so I know this is not correct, I want to get so brake fluid to spray around to see if I have any vacuum leaks. If I moved the idle up to near 1000 rpm I would get about 17 inches of Vacuum.
