As it looks like a governor problem you could try........

Disconnect everything except the water pump, start the genny and then use a bit of string, baling wire or bootlace to manually get the revs into the correct zone and stay there.

As it's a constant load it should stay wherever you leave it, with a bit of luck whatever is stuck could well free up with the warmth and vibration, should you be that lucky the motor shouldn't overspeed, the governor ought to shut it down.

Anyway, if you stand by it for half an hour or so you'll have moved some water in the right direction whilst Bob continues with the non bush engineering side of the problem!!

Cheers

Hi Bob
How is your time to further test / check the engine governor side please?

Jackie, you are lucky.  EdDee on this forum is a genius and he lives in EL.  I'm sure he can help you if he pops his head up.

Hi Jackie, I did send you a dropbox link where you should be able to download the workshop manual. Since I have very little faith in modern technology, I also printed and scanned the relevant pages and have emailed them to you. I also attach a couple of photos of of the governor assembly on mine before I rebuilt it.

When you get my email, please see the top left hand corner of page 39, it is very possible that you have this speed adjustment on your engine. If the spring is damaged it might well bog down under load.

If EdDee lives locally he would be an ideal man to help resolve these issues.

Bob

Hi Jackie, yes that type of governor works very well on my generator and holds RPM to within 1/2 a percent, even under heavy load. My generator is a Startomatic so it has a solenoid to switch the fuel rack on and off. It also has the adjustable throttle mechanism shown in the photo. the RPM can be adjusted by loosening and tightening the long bolts.
