Start with the mixture screws on all 3 carbs out 1 1/2 turns.Put your finger over each air bleed and adjust the screw for that air bleed in or out so that when you cover the air bleed the idle does not change. Last one I set up ended up at 1 5/8 turns on all 6 mixture screws.
1 1/2 turn out for all 6 mixtures seems bit much I don't want to wash the cylinders out. I will try by turning them out another half turn and see what it does.
