The unit cranks up and immediately over revs and then shuts down. This problem has occurred several times over the last year during crank up for it weekly exercise. I typically reset the control board and everything works fine for a few weeks. The unit will now not stay running even in the manual mode. I checked the choke and it does not seem to be stuck. Any help would be appreciated.

Hi
My 20kwh propane generac was doing this last year. Ended up being the stator, check how free the throttle is. If stiff replace it.

thanks

I replaced the Bosch Gov Driver Part#0E31610 with a new one I ordered from Ziller. The new part # is 0E31610SVR. Cranked the unit up and it runs fine now.

Before going the Governor Driver you should check the mag pickup. You can get the same fault. Over speed / under speed.
