The Pro Mac 1010s is alive well. Turned out the first replacement coil was also bad. Thanks to Heimannm for a good coil. I noticed the bad coils were gray plastic while the good coil is brown plastic - see photo. Maybe a trend with the gray ones? I was going to shoot a video but ran out of time. The saw wanted to die when I turned it on it's side so I suspected an air leak. Pressure/Vac test was good so I checked into the carb for possible flooding. One carb kit later and all is well. Video will come at a later date. Thanks to All for the input and suggestions, especially Heimannm and Maintenance Supervisor.
