6 Barrel Pro's - I need your input

Idle problems can be many with these things. Make sure ALL of the air bleeds are clear. The engine idles on all three carbs. I have both my outboard carb idle screws set at 1/4 turn out. My center carb is about 1.5 turns out. I'm running #65 jets in the center carb and a 6.5 power valve. You have to make sure ALL three float levels are adjusted correctly too and NO vacuum leaks anywhere. Make sure the outboard carb throttle shafts are not sticking. I have seen that happen too. Time and patience will be needed but you'll get it.
