I tried everything from 3 turns to 7 turns out. With that amount of idle gap, after a few hot laps, sometimes the idle will stay high. But it is inconsistent, sometimes it idles OK, sometimes it goes high, sometimes it goes low and dies. Seems sluggish on the bottom. Top end seems a little better but certainly not the monster that many others have reported. I'm able to get engine temps into the 220-230 range, but can't get higher because the performance is just not there.

I took the air filter off while running on the box to make sure the slide was operating normally and I noticed that there was a small amount of fuel splashing out of the carb throat. Don't know if that is normal because I never had to do that with my other engines . Didn't notice fuel on the exterior, but then I didn't look real hard either. The inconsistency is what is driving me nuts. Wish I had another carb that would fit, just to do a quick test. Not sure what to try next .
