Hello, need help. Working on a john deere buck. I believe it's the same as barmbarier trax.it will turn over seems to be firing outside of cylinder. I put gas /b-12 in head and it's not firing. Any one know what's up. Thanks eddie.

 

Easy to test plug, pull it, put wire back on , ground the ground strap to metal and have someone crank it over, use insulated pliers, etc, or you'll get zapped.
