Catastrophic failure due to lack of lubrication

Mower wasn't really worth rebuilding, from a cost perspective (15 yr old Craftsman with 6.5hp Briggs), but it was my first engine rebuild so I gave it a go. After a few hours of YouTube and a new piston, rings and connecting rod, I was able to get it all put back together. Still need some fine tuning of the governor to mellow out some 'hunting' upon start, but otherwise, once warm, seems to be running pretty regularly now. I guess the real test will be if she lasts through next cutting season.
