..SSR.. Posted August 19, 2005 Share Posted August 19, 2005 There could be a lot of things. Rev it high and bounce it off the limiter (if you have ignition cut, not fuel cut). If the engine flies apart, it was your valve tapping your piston. Link to comment Share on other sites More sharing options...
