Wow, a lot to look at. Thanks a 1/4 mile for all the suggestions. The engine was rebuilt 4000 miles ago so issues related to an aging engine I will skip until I have run through all the others. Of course, there could have been an error in the rebuild as well....At any rate, I will begin with the ignition system and work from there. The neighbor has a used stock one on the shelf since he is doing a rebuild now. He says it worked fine. This might tell me a little or tell me a lot. Will have to see and it won't take long to find out.

Thanks everyone. If interested, I will let you know what was going on when I find out.
