BOB, on a TO 30 Marvel carb ,how many turns out from stop on the two adjusting screws would be a good starting point ?
 
Idle screw at the top of the carb 1.5 turns out. Main jet close to the bottom 2.5 turns out
 
That might be a bit much. The IT manual has 7/8 open idle and 1 3/8 power. I use these initially and then tweak from there.
