One of the engines on my houseboat has started to backfire. The higher the rpm the more I notice the backfire. At less than 1200 rpm it does not backfire at all. It is a 350 Crusader (454cc).
Any idea what causes backfire and what might fix it? I put in new plugs this year but now am ready to do the points and all. Hoping that might fix it, but what else might cause a backfire?
