Am I missing something on the sight? All I found was #8 above in bold...

8. Allow the fast idle to continue for a few seconds, then advance the throttle to full. If the transition from low to high is rich, the regulator screw should be turned clockwise. If the transition is lean, turn the screw counter-clockwise to richen. Adjustment should be made 1/4 turn at a time until you are very close then 1/8 turn for fine adjustment. DO THIS ADJUSTMENT WITH THE ENGINE STOPPED FOR SAFETY.

I cannot find more of a description -- am I missing something?

I was afraid that I was setting it too rich but...

1) The only time I have much of a smoke trail in the air (yes on 30% heli) is at lower throttle settings. BTW, I did not notice an increase in smoke when I went from YS 20/20 to CP 30%.

2) The motor seems to be pulling the 16 x6 more toward the top of max rpms. I have leaned out the high speed enough to see it transition to 9,900 and pull back to 9,780 with a 16 x 6 apc on the high but as I went leaner I did not gain any RPM so figured I was maxed.

Thanks for your help Dave
