Here was the aftermath when I pulled the case apart on my Briggs and Stratton 11.5HP engine, lots of metal bits.
After I got the piston out this is what I found after I cleaned up the bore, unbelievable how just that one divot is all the damage.
And here is the culprit of the whole thing. As you can see, the rod is just not in one piece anymore.
Thankfully one of my coworkers is going to give me his old spare engine so after some paint and elbow grease my mower will look much better and run once again.
