I have a 9 hp Vanguard OHV engine on a Generac Generator. The governor does not work. It appears a spring has broken or missing. Can I get a schematic of this engine? How can I repair this?
is that a brigg and strat vangaurd if so give me the model and serial #s i may be able to get you some diagramsis that a brigg and strat vangaurd if so give me the model and serial #s i may be able to get you some diagrams

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.
have a load test done on the battery as it appears to fail when the current draw is high as in starting taking the current needed to run the ignition syatem
It is a simple but tricky job to explain here..I suggest you go into utube and ask that very same question starting with utube and then the question there are good sites that cover this..good luck..
Just guessing here, but if there is no control of the throttle and the engine over revs, then more than likely the governor control is broke. Briggs if famous for that problem. Governor is around 25 dollars and a lower crankcase gasket. Requires the engine to be pulled, lower crankcase removed, remove all pieces of old governor and then re assemble with new governor and gasket.////Before doing all this check that both springs are on the governor on the exterior of motor. If you manually hold the governor arm back, counterclockwise, and it still revs, then you need to replace governor. Don't let it rev for long or it with throw a pushrod or worse. good luck
Check you float in the carb I had one a few years back and it was partualy plugged cleaned it out and everthing worked fine. Also is the PTO binding up or bearings going bad putting an excessive load on the motor.
Thanks it is taken care of. Ron
it has been fixed. Thanks.
