RE: New Engine Break In
OK, well, 500 hours between rebuilds is pretty good in my opinion.
As to the fuel mix, just for example, my friend who taught me to fly in 2002 (Greg) has been running his Brison 50 on 100:1 full synthetic, as Brison recomends, for 4 or 5 years now, and he pounds on it pretty hard in the Pitts. My SV26 seems to love it as well. Im not at all worried about hurting my engine. Needle settings ? well, he aint touched his needles in years. Thats the other reason I wanted to go to gas. Actually, so far, I have been running my low end leaner than Greg because I don't like the 4 cycle sound so much. If you fatten to blubber, then lean to clean, on the fat side, you really can't go wrong I don't think. Gregs Pitts will go like heck after a 30 second warmup, but I need to warm mine up good before it will transition, but as I said, I don't dig the 4 cycle sound.
