Finally got some seat time yesterday mowing with the Ford. It would run fine for a bit, but sputter/stutter when I hit a bump. Thought possibly a bit of water in the carb bowl. As I finished up, it just died. No spark again. Pulled the sides off to check things out. Found a spot in the wire to the points that the insulation had worn off, grounding it out. So I now need to replace the wire.
Sorry for no pics, but the camera was here in Tulsa and I mowed in Collinsville. But I thought folks might want to think about this when dealing with a misfire/no start condition.
