Ok I went down and bought some good oil. It is Dumonde castor racing mix. It says it blends with alchol and gasoline.

I made a batch of 65% gas and 35% alchol and mixed it 40 to 1 with The Dumonde.

It looks like it mixed well. I tried some and I got my 45cc homey to fire and run about 10 seconds but that was it. Did you richen or lean the carb at all? I kept having to richen the low end to get it to fire?

I saw some Klotz Nitro koolia at the motorcycle shop. It says its 50% nitopropane and 50% koolia. What do you think about that for nitro? I spent all day looking for nitro locally with no luck.

I am worried the Denatured alchol will swell up me carb gaskets but I havent noticed anything yet.
So far its been alot of fun.
