I tried to upload the book for your plant but it doesn't let me.  Send me your email and I will try to get it to you that way

You can pick a 3 phase 1000v  50 amp bridge with heatsink from ebay for about $20.00 as I assume the dc goes to the X and X1 terminals.  If not it will be 6 1000v 20 amp diodes again off ebay.

Send me your email I will send you the book

This might help you.

On page 11 of the S.O.M. manual there is mention of a wedge which is on the valve lifter mechanism which I assume is some sort of compression release. It appears to release compression until the fuel solenoid is operated according to the book. On page 33 it shows a fuel cut off and exhaust valve lifter mechanism I have no idea how it works not owning that machine but this might be the place to start looking.

In your proposed setup the armature is made up of a ring of copper bars that are a short circuit. The stator ( the outside windings ) induce a current in these bars (by transformer action and set up a magnetic field in the bars which tries to keep up with the 50 c/s current in the stator. In your setup there only adjustment for load is to change the value of the external capacitor.                                                          In a proper generator the rotor has DC fed to the windings and provides a rotating field. Adjust the current flowing through this and you can control the voltage of the generator usually the voltage is fixed by the regulator and it adjusts the current to keep the voltage constant.    Delta means that the full line voltage ( nominally 415v ) is measured across each winding the The windings are shown as a triangle. The other connection method is Star these connections are shown with the 3 windings going to a common centre connection the voltage between the winding and the centre point is 240v. Google star and delta windings and you will see what I mean.  It is a bit more complicated than what I have described by that is a good starting point

This type of generator is only useful for fixed loads(preferably resistive) as the regulation changes with load. If you connect reactive loads like motors with a lagging power factor you will have to increase the size of capacitors to compensate. A rheostat won't help
Have a look at https://en.wikipedia.org/wiki/induction_generator

These values will only be valid for a set load. If it varies or draws reactive power the capacitor bank will have to be varied to compensate.

Don't forget you will be wiring these in delta so you only need 1/3 of the capacitance. Then the total of 64Ufd sounds about right by my back of the envelope calculations.

Don't have anything on the HA3 but the HA4 takes 25 pints so probably a bit less

There is no stop lever. The solenoid pulls the throttle governor lever open via linkage#2 and the external spring returns it to the stop position when power is cut to the solenoid.

If the ceramic former is still intact you can rewind them to the correct resistance. My Aux field resistor was crook and the resistance of it was so low that I was able to rewind it with 0.9 mm stainless mig wire.

I would have a look at the engine speed switch which is supposed to operate the main contactor or check the contactor coil for continuity.

Yes.  What you need is probably only a diode get it from ebey
