Gary, I think your right ! It has to be in the blood, maybe a high methanol level. I like your 110 Offy a lot nice work. Did you make the top half of the magneto? Are you planning on fuel injection or carburetors? I wound up using the FI from the old Lindberg Offy roadster kit as well as the vented side cover, the scale vs. engine size seems close enough for this project. But there's still a lot left to finish when I'm able to get back to my work bench again.
