Kind of late now I suppose...but, did you happen to check the oil before you started it?

if its turning over and no air is coming from the spark plug hole then its got to be a broken connecting rod, with any kind of luck it didnt hurt the block to the point it cant be rebuilt. that said if its over your head theres plenty of guys on the forum that you can send the engine to for rebuilding. good luck

Sounds like you threw the connecting rod

The good news is................if there is not a big puddle of oil on garage floor and no holes in the block, maybe it will be an easier and less expensive fix.

Another vote for the engine needing rebuild.

Rebuild that Kohler and get another 30 years out of that bad boy. Whatever you spend will be less than a new throw-away sheet metal "tractor" from Lowe's Depot.

Sorry to hear about your engine problems, but you can't argue with TheSaturnV's logic. Once the engine is rebuilt, anything else that could be or go wrong with the tractor can be be repaired/replaced for cheap and you'll have a tractor that will give you many more years of faithful service.

Not sure but I think J-Mech has an exchange program if your in a rush it may be the way to go.

20 years ago I bought a 129 that had a broken rod. I replaced the rod, pan gasket and head gasket. That's all. Been running great since then. No overhaul. Not even a new spark plug.

Your just lucky. :biggrin2:
