air cleaner clearence?

I suppose what you could do is get everything set up on the engine. The carb and the air cleaner your going to use in your Scamp. I have done this before, especially if I was unsure of air cleaner to hood clearance. I take a ball of tin foil place it on top of the air cleaner and slowly close the hood down to find out how much of a crush zone I have, and how much space is needed between the air cleaner and hood.
