I've had this little motor for ten years. Its always run really well. That is until last time I used it. It wouldn't start. It wouldn't even tro to start. After looking it over awhile, I noticd that the wires that go up underneath the flywheel had somehow gotten against the flywheel while the engine was running. The insulation had been rubbed off of them. I separated the wires out and used electrical tape to insulate them and routed them better.

The motor then started but it ran really bad. I pulled the spark plugs. The top one was clean but the bottom one was really oiled up. Cleaned and regapped them. No change in how the motor ran.

I know i'm gettin long so I'll just say that when both spark plug wires are attached it's only running on the top cylinder, but if I pull the wire to the top plug, it will run on the bottom cylinder. My theory is that when those wires rubbed the flywheel, they grounded out or arced and messed smething up........maybe a component under the flywheel. Its never been off that I know of.

I have a manual, but its not really giving me any clues as to what I should look at. I'd really apprecate any thoughts you guys might have. My 11 yr old boy is lookin forward to a fishing trip when he ges out of school next month (an his dad is too)

Appreciate the response. According to my manual, this lttle motor doesn't have a points system. It has a sensor coil and a power pack. The coils look to be outside the flywheel. The manual is confusing because it only seems to deal with testing these components on a larger motor with electric start. The plugs on the wires that run to the power pack and the coils are smaller and have less holes than my manual says they should have. I was hoping that someone might have an idea what could have been burned given what I described above. If any or all of it could have gone bad, then maybe someone could direct me to a link on how to test the individual pieces.
