My AC 716H has started to really smoke! How hard is it to put rings in one?

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.
