1650 cylinder shot

[Tim S.]

Pretty new to the forum been lurking here for a while. Rebuilt the carb on 1650 didn't know you were suppose to locktite throttle plate screws, they vibrated loose sucked into cylinder scored badly. Had a friend of a friend look it over and said also alot of play side to side on piston. he said the cylinder is part of the block and would be expensive to repair and said would reccomend finding a new mower.

I'm not much of a mechanic but I did replace the head gasket before the carb rebuild didn't know enough to check for cylinder slop tractor seemed like it had good power before but used a little oil, smoked very little. Does anyone have any advice as far as repairs or what is the best way out. What would be the cost of boring cylinder. The tractor is in good shape hydro works well needs a little adjustment on neutral setting. Thanks, Tim

Tim,

It's hard to say what needs done without looking at it. Expect to pay $500 to $700 to have your 16 horsepower Kohler rebuild. This is a ready to run motor. Some of the cost depends on if you use Kohler or aftermarket parts. You are removing and installing the motor.

I believe in the long run that you will save money fixing what you've got. Of course that may depend on if the motor has been rebuilt before and how large the bore is. If it's already out to .030 over that may be as big as you can go. May have to find another block to start over with.

Good luck!

You can resleeve a Kohler block if the block is .030 overbore. I have two K321 (14 horsepower) thats been done.

Thanks for the reply's guys can you visibly tell if the cylinder has been resleeved, I suppose you mic the piston and cylinder then check specs to see if it's been bored out before. Can anyone tell me where to find dimensions, or how much clearence is between cylinder wall and piston.
TIA, Tim

You need to contact this guy, I've bought a recon block from him with cam, valves, and head decked, and dipstick/tube shipped for $200.

You are correct. The motor was bored .020.

How is the motor doing?
How many hours one it?

Thanks for the info guys. Scott did you have to send your old block to have it reconditioned.

No I didn't, straight purchase. I never built this motor because I sold the 1450 it was to go in and I sold the motor. The guy does nice work.
