What I was looking for were more specific instructions for adjusting the regulator. For instance what to look for that would tell you the motor is rich or lean on transition.

It is #8 on your list.

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.

One more thing, how fast should I be comfortable spinning the YS110? I am thinking I might have to jump up to a larger prop or drop back to YS 20/20 fuel. --maybe it is not an issue with the style of flying I do because I am rarely at full throttle for extended periods of time.

At what RPM would you expect the valves to float?

Thanks Dave
