Before you decide to "just" put rings in it, you should remove the head and check the condition of the cylinder. A significant ridge at the top, or a scored cylinder will require that it be re-bored before putting in a set of oversized rings. Kohlers have the tendency to score cylinders. I have two Kohler engines that smoke some. Fortunately both of them have smooth, shiny cylinders, with no ridge at the top. A good honing and a set of rings is all that they need.

Also check for valve/valve guide wear. While you have the head off, turn engine till each valve comes full up. If you can see/feel much side play at all, then you need new guides & valves also. Worn guides cause a lot of smoke by themselves.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
