Sudden onset of over revving and high compression that wouldn't allow starter to crank the engine on Briggs&Stratton model 33R877-0009. Battery tested good with 12.7v and 370 cranking amps. Opened crank case and governor is broken into two pieces (on left side of attached picture), The other three pieces (on the right side of attached picture) were loose in the crank case and I'm not sure what they are or where they go. Any information greatly appreciated.
