Moderator Airhead Posted January 29, 2012 Moderator Share Posted January 29, 2012 Try a new spark plug first, better still warm the plug in the oven until its hot, then fit it quickly and try again. It would be best to remove the old plug and leave it out overnight to allow the flooded cylinder to evaporate Link to comment Share on other sites More sharing options...
