Now I knew someone would find the post here. And no I have found that bad here yet but with extremely lightweight Briggs flywheels it happen at anytime. I got one those flywheels in the recovered parts bin that is in nearly new condition where the idiot brought the mower from Walmart, put gas in it and started mowing his lawn. In less than 30 thirty minutes he bent the crankshaft and threw the rod. The rod broke and put a hole in the crankcase all because never put oil in the engine.
