Quick Fuel Slayer Rich!!!! installed LC-1 wide band

Ok thanks, the reason I asked was because I've ordered exactly the same carb and as I only have tuned a couple of Edelbrocks before I'm trying to learn as much as I can about Holley/Quick Fuel tuning and what issues I can get into.
I agree, the ignition must be set correctly before start tuning AFR and with all the actions you have described it could be a timing issue.
