scottg17 Posted May 20, 2008 Share Posted May 20, 2008 Have a compression test done... mine was doing it when cold and then progressed to doing it all the time..... turns out its a burnt valve... im in the middle if rebuilding it now.... Does it sound like the engine is 'spitting' when cold? Link to comment Share on other sites More sharing options...
