JVretenar is an unknown quantity at this point
Default no spark on 1 cylinder

I was running the sled slow dragging my ice fishing tent. It seemed like a plug fouled, I changed the plug and it was good for another day and then fouled (or quit firring) on the same plug again. One plug hot, 1 cold to touch. I changed the plug again and no change, hooked plug to wire without plug in hole and no spark. Can half the coil go bad or is there another control to the coil. It will run on the one cylinder.
