Just a quick update... I took the carb apart again...this time I removed the idle screws and cleaned and blew out those passages. Seemed to make a difference! Now I'm back to good again. The transition circuit between idle and full throttle was messed up...a gap between idle and mains was happening. I guess when I first "cleaned up" the carb, I didn't take out the idle screws and blow those circuits out. Dumb! It's usually something simple.
I have another Holley...a 4 barrel off an old Mustang... I took it apart this time also and "practiced" on it just to see what was going on. Now I feel like I can really work on a Holley. May even get some cams and squirters and experiment with my old '52 truck. Thanks for all your help and ideas...really gave me confidence to tear into that carb again with more knowledge!
