So I replaced the non-firing points and condenser. Also replaced the points grounding wire. Then all the parts were put back on the motor. Guess what NO spark on the upper cylinder. Hmmm. So I dug into it a little. After ringing all kinds of circuits I realized that everything rings to ground !!! Well that was not very useful. So I removed the coil and realized that there is a little metal piece through the middle of the coil. On the firing coil that piece rings to ground. On the non-firing coil it rings to nothing. So a new coil ?? One has been ordered along with some new spark plug wires. This is getting frustrating. Once the parts are here I will report if we have fire on the upper cylinder.
