Doesn't sound like the spary knew what he was doing other than charging you too much to NOT fix the problem. A new carby might fix the problem and hopefully it does. As for the governor, go to YouTube and see how to set the governor on your average 4 stroke mower engine and do the same. Firstly test that there is spring tension on it and that it does pull it back to position.
Can't think how I've done some a long time back but from my fadinng memory with the throttle at idle and engine stopped the governor arm should be at full throttle. Once it starts then it should return to idle IF not under load.

Working on more play time.
I know SFA about the generator/ alternator side of tis unit!
Wouldnt even know where to look for the regulator!
All you can do is send it to a so called expert, going by what you blokes are saying, this "expert"
may leave a bit to be desired!
With a fixed throttle instead of a govenor installed, I thought it would have been easier to control output voltage!
All you need to worry about with speed is frequency, were in Australia so it should be 50 hz
Revs control the frequency
Regulator controls the voltage
The governor controls what happens when current is drawn
So when Mum plug her curling iron in and switch it on, current then flows
The governor then tries it's best to keep the revs correct to maintain the frequency,the current drawn from Mums curling iron causes the motor to labour, the governor senses this and opens the carby a little, as speed recovers the frequency returns to normal and all is
The regulators job doesn't change, 240 volts and will stop it going above 240
So I think you need to sort the grain from chaff and start at the start
Whether carby is crook or not wont make much difference
If it gets a bit blocked in the carby, the governor will pull it open to try and maintain the revs
The regulator will still try and keep the voltage at 240
So Dad wakes up, puts the kettel on the current flow increases along with the demand for more power
The governor opens the carby up further and the motor picks up speed to maintain the frequency
Mums finished her hair and switches the curling iron off, current flow decrease so the governor closes the carby until revs are correct for the frequency
Kids plug their i phones into charge current increases, governor opens
Kettles done its job, current drops right off, the governor closes the carby a lot
This whole time the alternator should be doing its best to run at a constant speed (revs) to maintain the frequency 50 hz, this is very important for a few reasons
Voltage regulator should be constant at 240 volts
A capacitor is like a battery and will absorb spikes and dispate them slowly
I am guessing without ever seeing your generator the purpose of the capacitors purpose here are to smooth the power out, that is a guess only as I haven't seen any of this
Dunno if this of any help or not
Maybe check the regulator is grounded properly
Maybe check its connections, if the connections are crap it wont be able to reference anything to base the voltage on and will be all over joint chasing its tail
You will need to find a frequency meter now to set the governor again
Frequency is critical to safe operation
Keep us posted
Your better to die trying than live on your knees begging
