carb help

First thing, check idle vacuum, the power valve should be 2" below idle vacuum. If your engine pulls 7", then you need a 4.5" power valve. This is typical with a big cam, then you want to get the main jets tuned in at about 3000 rpm cruise, then reset idle mixture and RPM, set WOT secondary jets, finally set the vacuum secondary opening rate with springs ( if vac secondaries)
