Ray, George, and Chris:
All's going very well. Just a few more heat cycle runs, and it'll be ready for flight. I figured out the compression setting and am getting high RPM with a steady run. The exhaust is clear; no color. It seems to like the 7x4 prop for the higher RPM range (with higher compression), but it sure eats the fuel! I'm alternating the 7x4 with the 8x6 for break-in.
Thanks for all your help.
Dave...
