Troy,

I have ~2 gal run through my 110. I've adjusted the valve tappets at .0025, I'm using pro-pattern 25%, swinging an APC 16x6, and burning an OS "F" glow plug. I get top end at 9,200 (richened down from 9,500), and an idle at a steady 2,000.

Now my question is directed at the mid-range of 4,000rpm's. How steady would you consider that rpm needs to be before you're satisfied with the regulator adjustment. For example, mine fluxuates +/- 40 rpm. I feel like that's pretty good, but should I strive for a more "rock-steady" 4K?
