Use 2.5 turns and reduce idle.. I did mention it could be the bottom. I own an Inferno and it was a difficult puppy to run in and tune the settings from factory

If your engine over runs hi rpm when you've cleared the crank of fuel after revving it out at full throttle then the idle gap is still too large and you need to lean the bottom needle and reduce the idle until she revs out and drops in idle nicely. It should have a healthy puff of smoke after idling for a few seconds.
