I just made a big mistake. First I paid too much for a 1974 ($600) but it looked real sharp and I knew what I was buying iy for, sort of a yard tractor for my wife and I could cut the rough stuff out back a few times a year. Well, it didn't last five minutes. I would say it ran for two minutes before my son ran the rpm's up real high then engaged the deck. I was coming after him to slow it down when I heard that unmistakeable sound of a rod letting go. I got the engine out and tore it down (It's a Kohler 10 hp) model K241AS. The only apparent damage is the busted rod. My question is how dumb would it be if I just replaced the rod & bearing assembly, threw on a set of piston rings and put her back together without pulling the crank and having it machined? Should I just throw the whole thing out and kiss off my $600? Should I buy another engine, or should I take the engine to a shop and have them put it right. Either way I go I'm in too deep. Any market for John Deere lawn ornament? Has a nice paint job and a brand new seat. Thanks for any advice. John Gov.
