Voodoo Posted July 21, 2008 Share Posted July 21, 2008 Try changing the spark plugs, sounds like its not burning the fuel sometimes, hence the pop when it does eventually ignite. Quote Link to comment Share on other sites More sharing options...

Sam The Man Posted July 22, 2008 Share Posted July 22, 2008 Sounds similar to my problem ( viewtopic.php?t=13182 ) which i think it is the spark plug Quote Link to comment Share on other sites More sharing options...
