As Mat already said Tom, you'll need that number 30 carb...
Tom H. cool flywheel, watcha gonna run with it?
I was bored this afternoon and made cardboard fender templates like Brad D's cub (found s'more pics in the vault...). If I get the steel, and can find a press brake that I can use... I will have to build them fenders... fun project... But I have one question, what type of lights did he use in the fenders??? I can only find 4" ones, too big I think.
