Thank-you to everyone with all the good tips. I solved the issue. I did a voltage check where the starter switch wire attaches to the solenoid. Whilst my wife turned the key, I measured voltage and found when it did not engage, I only had 6volts! So after tracing the three red battery wires from the big square connector on the top of the cowl, I found the issue. Down behind the distributer, the previous owner had 4 wire breaks butt connected poorly and corroded. One of them even had a short piece of 16 gauge wire in between the butt splices! All of course hidden under electrical tape. I re-spliced, soldered and sealed with heat shrink. And wallah! Strong perfect starts every time. Finding hidden masterpieces of these hot messes is never ending!
