Its only been 2hrs and its Sunday evening,Im sure everone is with their families.  Someone Im sure will be along to help. Whats your compression and or dome size cause that will have an effect as well. What is the jetting now,have you run it yet? If so how does it run in all ranges of throttle,is there an issue with how it runs,ie are we trying tonsolve a ridability issue or just a new setup? Whats the temp where your at?

Start fat. 180 or larger main. 52 pilot. Set air screw to achieve highest idle. If more than 2.5 turns out put a smaller pilot. Less than 1.5 go larger on the pilot.
