Question for Holley carb gurus

You're good! Hit it on the nose.

The problem I was having was running pig rich at idle and a tip in bog. I couldn't find a cure for either. Kept fouling the plugs, black smoke out the back...you know the story.

I adjusted the secondaries but now I wonder if it'll idle too high. I only opened them up enough to expose just a square of the transfer slot. I believe the carb model is a 3310. It's a VS 750 cfm.
