Thank you for your comprehensive commentaries. I'll check the dist. rotation. I'm hoping it is correct because I'm certain it is the same Delco number as others on this forum use for the same tractor. I might even ask that in a separate post. I had liked the mag ignition on this tractor and probably would never have changed it over. When it quit, I decided in the long run it would be easier to maintain the distributor than the mag. I'm not sure I want to sell it at this point. It is not a Case mag, but rather a WICO replacement. Sounds as if you are looking for an original Case mag.
I'm beginning to feel better about this now and really appreciate this forum, (as I have in the past as well).
