Re: Briggs 28N707 15HP Died and Won't Start
I would take the flywheel off and directly check the key. It may look intact, but the only thing that 'happened' was the extra load of the grass.
Otoh, if the governor tried to open the throttle, and tried a bit too hard, it could have messed up the linkage or the internal governor parts.
Does the throttle open all the way when you move the hand control to the fast setting? It should, and the governor link should let it. You should be able to move the governor arm back and forth, and feel a slight resistance as the bobbin moved up and down on its shaft. If the governor arm just flops, I suggest dis-assembly and inspection...
simplificate & add lightness
It's not how hard you work, it's how much you get done.
