proform race carb / Idle trouble

Did you verify your fuel pressure and float levels? I have the same carb, similar idle problems, was idling over 1,100 rpm. My fuel pressure was unregulated and was 11-12 psi with my Carter mechanical pump. Plus, the float level was almost at the top of the sight glass. Solved those issues now it's at 850. Never touched a jet or an air bleed. IMO, air bleeds are really only for fine tuning.

Might also check to see if your throttle linkage is adjusted properly.

I think that the jets that come in these carbs are 74 and 84.
