Can you explain what you want to know in a little more detail please. I find it difficult to understand that long single sentence, and how does it relate to your heading?

3 ph ~300v 750w genset alternator: wamt tp feed in ac power from inverter. to start petrol motor 200w should do it. single ph might be ok 50hz ideal. would need start capacitor to next ph. dont understand maths/motor theory.

He is the guy who keeps wanting to do this thing. Same guy seemed to think a sewing machine motor could start the generator.
A sample of how this thread will go, over time. -

You said in the other thread the gen was hard to pull start. If you are capable of carrying and moving around 8 to 10kg, why can't you pull the starter cord? I'm doubting it would take 1/2 of that amount of weight to pull start the motor.
can lift dead mass, but not pull starter cord/hold genset down. without much pain. very weak. can just hold 1kg with arm extended for few sec.
