I had Thumper fix that thing aft I tried to make it run...Save your self time and money, and just get a Thumper carb...For a $1200 carb, that's no place to start out.

Boosters are tight. I finally had time to closely examine. There were two different size idle air bleeds. Called Holley. 16 minutes on hold. Tech contact verified bleed size was wrong. I had the correct bleeds in 2 days. Pretty good service. Pretty bad Q.C.
