I have an old Craftsman snowblower with an HS50 engine on it. It used to run great, but we stripped a gear in the snowblower and put it in the barn. I got it out to put the engine on another snowblower, tried to start it, and there was no spark. I tore it apart and set the points, timing, air gap, etc. The flywheel key looks fine. I put it back together, grounded the plug, and gave it a few pulls. It had a bright blue spark everytime. So I put the plug in and tried to start it. Nothing. I took it out and grounded it again and it had no spark. This is becoming the most frustrating thing. What could be happening?

Probably build up on the contact points causing high resistance and intermittent operation. Try filing the points and resetting and see if that makes a difference.

Best of Luck....

That was the one thing I hadn't tried. So I sanded them down a little, and it started. Thank you 30yearTech.
