gotta_goatsfast Posted April 3, 2011 Report Share Posted April 3, 2011 Are you sure it is in your top end? What is your compression at? It could just as easily be a problem in your carburetor. Pick up a clymer's manual and start getting greasy. Quote Link to comment Share on other sites More sharing options...

Did you let it idle for extended period of time? Were you hard on it right away? Quote Link to comment Share on other sites More sharing options...
