only idle with an airleak sounds like the pilot is rich, but that goes against what everyone else is running in them, at least on ported cylinders...the 50 pilot, try a 45 pilot, thats what my 34pj likes ????
and my airscrew wouldnt effect the idle at anything bigger
you're just gonna have to keep going up and down on the pilot till you find the one that idles the best with the airscrew under 2 turns out, and the airscrew actually has some effect on it
