Well Don all carbs and motors are not the same but here's what I do. Low speed 1 to one and a half (some say up to 2 turns) On the high side your motor will be the judge of that, the hotter it gets the more fuel you'll have to give it, start it at 1/4 turn and tune it until it runs strong. Also you'll want your RPM's to be between 14.200 to 14.600 hope that helps

Don:
Be careful. Every engine builder blueprints their carbs differently. It depends on the popoff setting and fulcrum height along with the hole sizes. I would ask your engine builder on the settings. If you haven't had it blue printed, I would suggest Kyle Adkins in Port Washington, OH 740-498-5157.
FYI we set ours at 1 5/8 on the low and 1/4
