At maybe 15 tanks of fuel through it, I'll give it a thumbs up!

Oh, and one other thing. I was pretty sure I'd be OK, but confirmed it this afternoon. 20cc engines are supposed to run 32:1 fuel/oil mix? They run fine on the 20:1 that the 10 needs. It's not soaking wet underneath, in fact I noticed no difference after a day of flying. Carb did need to be tweaked, but this engine hasn't been run since last summer, so I don't know if it was that or the difference in oil. HS needle was maybe a blade width rich. That's it, so no big deal either way. Noticed no difference in power. It's in a 70" GP Revolver, so it's kind of a hot rod. Pretty sure I would have noticed much difference in power, but in all fairness it was not tached before and after.

Point is, I'm no longer concerned about running 20:1 in my 20cc engines. We can still have just the one container of fuel for the 10 and the 20's. Will check out how a 30cc does on 20:1 when I get a chance, but I suspect I'll see similar results. -Al
