Ah, there was 2 or 3 chainsaws on ebay at 85CC and 112CC engines(I think they were dual cylinder engines). 66cc sounds like a good size, but can they run on methanol ok? Have a good place to get it and has a but more punch for a price, but I think the engine needs a 8-9:1 compression ratio to run good with it. I think the frame will be the easy part , the rear drivetrain will be the pain in the rear to make. I dont want a chain driven rear end

Thanks guys
