holley carb help,transition/stage
You need a 4 corner idle circuit carb . Square the primaries and idle off the secondaries. Stumble should get better .
Vacuum at idle divide that in half and that is your power valve number. Any motor under 4.5 valve should have a 4 corner carb or drill holes in the venturis until it idles with the primaries squared. If your past square your into the emulsion jets and it will stumble like a dead spot when feathering the throttle
