You should be set at 5 lbs at idle. You could also raise the needles and see what happens. The needle will affect the fuel up to about 3/4 throttle so you may have issues with both needle and main jets. The pilots honestly don't really do a whole lot in the big scheme of things. I wouldn't bother running it with no airbox as that won't point you in the right direction.
