Moderator Airhead Posted January 2, 2013 Moderator Share Posted January 2, 2013 take the sparkplug out and leave it out for 24 hours, try again after you have checked theres a spark Link to comment Share on other sites More sharing options...

Moderator Airhead Posted January 2, 2013 Moderator Share Posted January 2, 2013 Listen joe, I have no idea fella but dont rush into it just yet. Leaving the plug out overnight and then try again tomorrow, preferably with another plug...have you checked it's sparking? Link to comment Share on other sites More sharing options...
welshjoe Posted January 2, 2013 Author Share Posted January 2, 2013 yea mate checked the spark plug and its sparking proply but then i check the compression and its really low. So i think it must be something to do with the pistion. Link to comment Share on other sites More sharing options...
