Another prop question: 20' MA advice?

[rkarran]

Thanks Sandman! I did the decarb today but haven't tried to see the difference yet. Stiff wind dispersed the smoke pretty good.
I do run non-ethanol fuel and do have Champion plugs. The motor only has 417 hrs. Will take your advice on the leg lube, wp, and t-stat. Thanks much for all that. I gotta find some other props to try, once I benchmark the one I have with speeds and rpms. I know I must turn more at WOT.
