It's been awhile since I've looked for the record. 

I was thinking of maybe a Sten's set...

 

Can you take a .010 over set and file-to-file like on car engines?

He referenced Kohler. But again he said he couldn't find them and was disappointed. He said the ring set is normally $30-35. The one that was $184 was number 41874 which includes the piston. He said "three thousands over" so wouldn't that be .003?

Yes. Kohler and after market don’t make the .003 any more.

did he use a cylinder bore mic in the cylinder?

Tell us what he’s going to do?

80-90% what’s that? 
if he’s only going to just put rings in that then yes 80-90% for a few hours then back to smoking if it needed to be bored. 

 

I'm not an engine expert by any means, but what you are saying sounds reasonable. If it is "that bad" and the rings don't do the job, then it would continue to smoke. This guy grew up working on wheel horses in his dad's shop which was a dealer, so he has 50+ years experience with them I would guess and he still currently runs the shop in a rural area. I'm not saying he is right or wrong, just that he definitely has more experience with wheel horses compared to the average lawn and garden shop. He also mentioned that if it needs to be honed you would need a new rod as well most likely otherwise the original could break due to more stress.

Nope - I haven't taken the motor to him yet. Just had a phone conversation with him to get an idea of what he was suggesting for options.

then how does he know what needs to be done?

No disrespect but wow. I wouldn’t have this guy check the air in my tires.

I'd have to agreed. 

 

I've NEVER met a machine shop person who would give you a straight answer without seeing/measuring the engine.

He was simply telling me what the typical options are. I'm guessing that he had quite a bit of success in the past with that method. I'm also assuming that if I brought it to him, he would check it out and let me know if he thought it wouldn't work due to the condition of the engine. No idea, but I'm just saying he did the best he could to give me an idea of what I'm dealing with, especially without seeding it.

Can't argue with that, but I wouldn't say he gave me a straight answer. He was more just telling me what he's done in the past. I'm sure a lot got lost in my translation of the phone call. Also - I doubt he would be the one doing the machining. He works with other shops for that from the sound of it.

Considering what you guys are saying, it sounds like I should ask him if he can check it out closer if I bring it in and then indeed give me a straight answer. Then if he measures and checks everything out I would know he is doing the proper due diligence. On another note, my friend has an early 70's cub with a 12 hp Kohler and he's planning to pay someone 1200-1500 to completely rebuild it including paint. I would definitely consider that if I was using this to mow, but that's not the case.

Find out if there's a fee for that....

I have done this with good results when standard rings have a tad too much end gap.     :handgestures-thumbupleft:

wow. I need to raise my rebuild prices. 1500.00 is more then double what I typically charge.

This might be worth asking about.  However at this point I'm not ready to restore and rebuild the tractor, so if he can't get the oversized rings I'm not sure its even worth my time to have it checked out right now. I might just sit on it for a bit and look for another one that doesn't smoke. And then when that one craps out I will have extra partsB).
