My ski is "cutting out/stalling" on acceleration. when I back off a little it catches up. It seems like a fuel issue but I'm wondering about this TOPS valve I've been reading about...what are the symtoms of a faulty TOPS valve. Also I noticed the hose on my catch has some kinks in it and wondering if this would affect my performance. I'm going to relocate the catch can, I don't like the current arrangement. Gotta get it ready for Mud Bug!
