I had my first good run with my Listeroid 6-1 Saturday. I call it a huge success, the culmination of many hours of thought, elbow grease and studying the wisdom of others. Particular thanks to George Brekenridge.
The 6-1 is coupled with Harbor Freight 10KW, 3600rpm, 2-bearing head. It was found still in the box on Facebook Market Place for $200 at an estate sale. While the 6-1 will never put out much more than 3KW at the reduced power it should outlast me. This simple, unregulated brushless head handles the unbalanced 120V / 240V loads much better than the 3 brush type Chinese ST-5 heads I tried.....
The rudimentary flywheel balancing / equalizing I did two years ago is pretty close. It tends to slide a little bit under a 2500 watt load, but that might be because the governor is drooping 8hz from 62hz at no load to 54hz at 2500 watts...... (In the picture it shows 61hz at load, but that was after a manual adjustment.)
I'll work on the governor next.......
