I was just wondering how many of you have had a motor go bad, then replced it or shortblocked it, because you thought it wasn't worth fixing. A friend of mine was thinking of doing something like setting up a motor replacement, or a mail order service. So far, he has rebuilt 7 for local lco's (he is an lco himself) and now has 7 more fresh motors just waiting. These are all Kohler 25's. He did one for a friend of mine, and this friend told us that that motor NEVER ran like it does now. He can't believe the power and the smoothness. Anyway, this guys plan, is to be able to bring someone mower in, and within about an hour or so, he can have the motor swapped out with a new one. He's thinking he'll charge $1000. and give a 1000 hr. guarantee. I know for a fact that this guy definitely knows what he's doing, and his cousin that works with him has a degree in diesel mechanics (even though he works on everything, including racecars.) As long as no permanent block damage has occured, there should be no trouble rebuilding these motors. The way this came about, was he was told by our local dealer, that these Kohler 25's could not be rebuilt, due to the cylinder being out of round. Well, after just buying new for his seventh Lazer, (yes, he runs seven constantly) his cousin wanted to inspect one of the old motors that these mechanics had inspected and said could not be rebuilt. After scoping the cylinder walls, it was discovered that there was nothing wrong with them. Now, this is after $14000. has been spent on new motors. Don't think for a moment tht this friend of mine wasn't ticked at this dealership for being decieved. Anyway he started rebuilding them, and has had great success with these motors thus far, and has several people in this area coming to him for more. Right now, he is currently doing one of the new fuel injected 26 hp motors for someone. I'll let you know how this turns out. Anyway, I was just wondering, how many of you would be interested in going this route you were in need and it was available.
