Blown Engine Repair
Now this isn't your typical car engine... it is your typical 11hp Briggs & Stratton lawn mower engine.  The piston rod snapped into several pieces, one of them slamming into the crank case wall right next to the starter motor. It only cracked the metal and pushed it out a little. I pounded it back flat. The question is, if I get it welded up, insides cleaned, and the piston rod replaced, would it work?
I know you know don't need compression in the crank case, just need to keep the oil from leaking.

 Actually, I HAVE raced it in the past.... but the thing is twenty years old. That and it was trying to move a flat tire backwards up a hill.

probably, but while you are at it, go ahead and do a rebuild with new rings at least, since it's so old, it could use some new life in it

while youyr at it youy should go for a bigger bore, port it out, high flow reid valve, lightend flywheel, nitrogen hardend piston, decomp plate to 12:1, and nice big garret on the side. you'll have to replace your welsh plugs coz you'll prolli end up with more pressure in your crankcase than in your cylinder. lolz =[]
