Thanks for the link. I will keep all of that stuff in mind.

What is the carb setting technique for these engines? Is it similar to a glow engine? i.e. set high speed needle for clean full throttle first. Then set low speed idle for reliable idle and good transition from idle to WOT?

Also, what are the signs of rich and lean running, particularly on the low speed needle.

I believe we're using a 20x10 Zinger Prop. Any guesses of what full throttle RPM would be?

Thanks again,

Tom
