I have read many posts on the idle mixture screw adjustments on Holley carbs.I read 1-1/2 turns out for a starting point on all carbs. I have read 3/4 turn out for a starting point.
I have been told from cab. experts 1-1/2 turns out on a 2 corner carb. and 3/4 turn out on 4 corner idle circuits.
Does anyone know for sure what is the right amount of turns for a starting point? 3/4 to 1-1/2 is quite a difference.
