Well, I have 22x8 props (menz, MSC, NX) and they turn from 7200 to 7000 RPM on the ground. This doesn't seem like too much prop since DA recommends not going much over this RPM. I also can't seem to go to the rich side on the high needle. Isn't it possible that the selected carb worked fine at higher elevations / temperatures (i.e. AZ), but it was on the edge so that it required a fully opened high needle to get a drop in RPM. Then those of us that run at sea level at lower temps can get it just to around the peak and can't go over to the rich side? I am really thinking about drilling out my HS needle because it makes me uncomfortable to not be able to tune to the rich side on the high end.. I can't get it rich even with 100:1 amsoil.
