Aero nut,

What is the mix ratio you use for your fuel? Also does it run fine inverted? I did run a poulan 42cc on glow and it did run well upright. I didn't put it in a plane inverted so I don't know how it would have done. I used 1 part car fuel, 12% oil and 20% nitro. I mixed it with 2 gallons of methenol. I did need to enlarge the fuel passages to get enough fuel in. It would not go rich enough without doing that. I like your idea alot more. The carbs will take the alchohol no problem, but with your setup, they will not need to be modified. I have some 18cc'c I would love to try it on.
