Re: hi everyone, does anybody have any ideas for me?
If your plug was not tight it probably just backed out. If the threads are fine the head should be fine, however your cdi doesn't like to run w/o the plug grounded to the motor. It is possible that your cdi is damaged; typically they work or don't but there is no law that says it can't be damaged and still work poorly or intermitantly. did your plug electrode get closed/damaged. Start by checking that you have a fat spark by removing and holding against the head and rotating the motor. If you have a repeated fat spark then that is not your problem. You could also just replace the plug and see if that fixes the problem.
