Disconnect wires and use a Fluke meter 16, typically used by HVAC techs. (It has a capacitor charge function) You cannot use a multimeter accurately. An old analog meter on ohms, will show a reading then decay, all that tells you is it isn't open, it does not tell you if it is holding correct mfd capacitance

The circuit board controller is monitoring the engine rpm and frequency and thus controls the frequency, via the governor actuator, or stepper motor as you say. You can't adjust it. I doubt this is the problem it sounds like either engine is not delivering HP, or there is a stator short causing excessive load / current draw bogging the unit down, incorrect wiring of the stator output. Ha someone taken the stator output leads off the breaker? check the stator resistance and shorts to ground.

Check the online support of these generators, or look at this operating video for information: Generac 5000 watt 6250 surge watt generator running

It sounds like the main jet is still clogged, or there is an air leak- like one of the carb gaskets is not seated properly.

Does it stall when open the choke? If yes, thoroughly clean the carb.

At 240v, a 15KW generator will produce appx 62A or 31A per 120V leg. Therefore allowing for some overload, a conductor sized for 35A per leg would be adequate, but you should verify local code requirements.

check spark plug or plugs then carburator.

Remove and clean carburator
