I can put this one to rest. Upon very close inspection I found that there was a small rip in the wire insulation on the condenser. Being such a TINY points box on that 1250 I'm sure it was intermittently shorting out on the engine block. I ordered all original Wisconsin parts which included a coil, plug, wire, points set. I got everything installed and adjusted the points using a meter. The tractor runs very well now. It's nice to have it back.
Just a quick thank you to Bolens Parts and Supplies for his quick turn around time on orders placed. Our sponsers here great. I've bought from several over the years.
So, the points setup on this 1250 is a nightmare. There is almost no room to install a set of points and condenser in the tiny box on the side of the engine. There's a small copper grounding strip that is near impossible to install onto the points and hold it all together when trying to secure the points onto the engine block. The Bolens engineer who came up with that design was out to lunch. Here's a couple pictures of the points box before I replaced the points.
