If you are living in the Toronto area, there is a fellow that supplies parts and does machine work in Brampton, On. His name is Michael Paznar. I have recently sold him a bunch of Kohler crankshafts. Just google Michael Paznar in Brampton.

Thank you, that's what I did!

As always, I appreciate all of your advice!

Quick question to you guys in the know. The time will come when I'll buy a .010 rebuild kit for the STD block that's on its way to me. I prefer to buy things from local people, to support them, but out of curiousity I have looked around and see wildly varying prices, from $80 to more than $200. How does that make any sense? - is it the quality that's so different? Or simply the trust in who you get it from? Or a combination of factors?

My opinion:

From my GT pulling days using Kohler K's, I like quality parts in the rotating assembly. Kohler, Stens, aftermarket racing manufacturers, etc. The last thing you want is to destroy the engine by saving a few bucks on a cheap connecting rod. Gaskets, carbs, and the like, the cheap ones are fine. Just watch out for some of the goofy head gaskets I've seen floating around. The cheap fuel pumps are junk too. I did a post about those.

There are companies that sell middle of the road priced kits that stand behind their parts. Those will be fine in a stock rebuild for one of our tractors. I used one to rebuild the K301 in my dads JD 212 and it has been cutting grass for several years without a problem.

Make sure your machine shop has the piston before they bore your block. A good shop will require this since pistons have variations. Your machine shop might be able to supply their preferred kit as well. I'm not familiar with Mike but he seems to be highly recommended by the group.

Good luck on your rebuild.

Ordered the engine kit for my K321 rebuild from this fellow on ebay. It's been mowing 6hrs/week for the last couple summers and running perfectly. Would suggest the kit with the valves to save potential time. Bearings were purchased from a local bearing house.
