Hi everyone. It’s been a long time since I last posted. I am having the devil of a time trying to setup a Briggs and Stratton Vanguard 24 HP motor on a friends lawn tractor.
The engine was running rough, and was hard to keep running, initially. After spraying some carb cleaner into the intake, and adjusting the armature gap for the ignition coils, the engine speed ran up and down (hunting), which led me to believe that the governor needed adjustment.
I have a copy of the Briggs service guide for these engines, ( this one is a 440000 series ).
The manual shows an adjustment procedure that does not work for me. It says to hold the governor shaft in place in the farthest clockwise position, while making sure that the throttle plates are in the wide open position, and then tightening the bolt that clamps the governor arm to the governor shaft. Various u-tube videos I have seen state the same thing.
The engine runs at full speed, ( out of control ), after adjusting the governor like the manual said.
In the early stages of trying to adjust the governor, I made some mistakes, like having the governor shaft fully counter-clockwise, and/or mistaking the throttle fully open versus fully closed position.
Trying to run the engine after the mistakes resulted in a very loud clicking sound coming from the motor. I immediately shut the engine down when I heard that sound, both times, but I can’t help but wonder if I have destroyed the governor assy inside the motor.
The spring connections and operation for the governor on this engine don’t make sense to me.
Can anyone enlighten me, please.
Thank you in advance.
Cheers.
Andy
