I think a 3 phase converter will give you about 70 % of the motor's hp. It has to do with power factors and efficiency. My dad used to make converters for farmers. He would take a lathe and shave off some of the armature on the motor used to make the 3 phase. He also make static converters using 2 different banks of capacitors. One bank was the starting capacitors and the other were the running capacitors. I forget what the rule was for capacitor size/hp. He would use adjustable timers and motor contactors to connect the start caps for about 1 second and then another motor contactor to pick up the run caps. After you got the motors under load, it was a matter of fine tunning the total capacitor size to minimize the current draw. He would also install bleeder resistors to drain the caps before restarting the motor.

On our first cosmetic restoration, not having a manual, we carefully marked the wires, taped the magneto in the position it came off, and were careful not to turn the engine over while we had these components off. We thought we could get by with this since the engine ran perfectly and would not need any internal work. After the cleanup and painting was done, we began reassembly and finally came to t
