Roger I am using about 4cc MMO to 60cc camping fuel white gas. When I pulled the piston everything was nice and oily (including the combustion chamber)
I think the fuel lube can be leaner still. I am also cutting back to oiling the crank and rod/wrist pin about once an hour. (30w) oringsandmore.com has about everything covered, I think 25 were just 3 or 4 bucks.

I'm at the point now where I don't think I can hurt it!
If you play with fire, you're gonna get burned.
