Badger running fine than no spark. Pulled plug and laid against head and no spark. Moved plug about 1/8" away from ground and plug sparks.New plug sparks correctly and atv run fine for 1/2 hour and no spark again. Held plug away from ground and plug sparks. Tested coil and primary side okay but secondary side tested higher than manual spec. Im no electrical expert so any body got any ideas? Spring has sprung in ohio and its time for junior to get out of the house before he drives his mother crazy!!!!

 

Seems like plug fouling, either too much oil getting to it, or too rich a mixture. If the plug nose is black and sooty, it is fouling.
