Wow that's strange, I have never seen one like that before. Looks well made! I would like to find more information on these. Thanks!

In SW Wisconsin the going rate is $75.

Our local Vo Tech school has a fixed honing machine. I took a nite course for small engines and managed to use it a couple of times. It works great. For one engine I honed it a few thousands to get the cylinder round and straight again and then knerlized the pistons (puts a cross hatch on the piston skirt and expands them slightly).

I aint never seen that trick before. I guess thats what paid lernin' will get ya. I read once that the piston skirt is where the compression comes from and the rings are just there to keep the oil in.

I just had my Kohler 16 hp sleeved this year. I believe I paid about $200 including the sleeve. Cylinder was .060 oversize. Boring should be about $100 unless you live somewhere out in the boon docks where the cost of living is a lot less expensive. Took mine to a automotive race shop, not too many places around that do sleeving anymore. I could have shipped it to down south but by the time I paid the freight I'm back to $200.

A little less than 50 bucks a hole here.... at the local auto parts store that has an in house shop... has 'em resurface the valves too, another 25 bucks. I had to boil/ clean the block afterward though. They did a poor job of that...

That's the same basic hone that I have. The big knob gets it out close and the little knob moves the stones in thousandths. Stones are replaceable and come in coarse, medium, and fine.

Doug would that be able to do a cylinder that had some taper to it ? One that comes to my mind right now was worn about .008" bigger at the top , thanks , Al

I was just checking locally today and was quoted $50 to bore the cylinder, and $50 to grind the crankshaft, with another $35 to reseat the valves.

I have that hone. I took a 12hp Briggs aluminum that was scored and honed it out to 0.010" over. It took an hour because I clean frequently and let the tool do the work. It came out straight and round( plus or minus 0.001") by taking it slow. The scratches were too deep so I got another block at the dump and overhauled it. But honing with the right tool and technique works well.

Sure, it will take out the taper or out of round. The thing you need to watch is bore size. I forget exactly what range mine is but I think it will only go down around 3 inch or a little more. They do make the same thing for smaller or bigger bores.

Well I just got back from dropping my block off to be bored out. I just hope the cylinder is at least round when I get it back, I am so not used to other people doing work for me. :biting_nails:

Might want to start pricing new pistons. May I suggest this style?

OHHHHHHH!!! Where? I got a K341 I need that done to. I do think I found a guy about 30 minutes from me, some go kart racers use him. I would like to have options though.
