Getting everything ready for winter, the lawn tractor is being a pain in the butt again. Didn't want to start, evidence of water in the fuel system AGAIN despite using water remover, ethanol-free fuel, and stabilizer.
After much peepeeing around, finally got it to start and go into the garage to replace some other parts -- voltage rectifier, clutch spring, etc. Meant to make a project video on it but ended up not.
Came across this engine on marketplace. Nearly identical to mine, same year and plant and everything. He said the PTO bearing seized, engine stopped and threw pushrods. For parts only, $100.
Heck, a replacement genuine carb is $200 and the knockoffs don't work worth a darn, plus my ignition coils have seen a few mice in their years.
Picked it up and began tearing into it. One pushrod bent, the others are straight but fell out.
Put the straight ones back in, spun it around, and the camshaft is still good. Direct-gear so I doubt it could skip teeth without very obvious indicators.
Decided to go for broke and pulled the heads off, knowing I'd need to buy new head gaskets. No slop in the connecting rods and the bores themself looks 
Despite being 10 months older than my engine, it overall looks to be in better shape. I think I just need to toss some new pushrods in (which i have spares of already) and she'll run better than my own. $50 for head gaskets sucks but isn't terrible
