If you have a dislike for the Tec engine you will never be happy with one so why spend any money on it? I would go for the Kohler and see how the replacement would work out. Can always fab up something that will work.

If you get the 212 and it needs the engine rebuilt you will have way more than $158 rebuilding it.I suggest you pull the head off of the K301 in the 212 and make sure the cylinder bore is good and straight.If you put the piston down in the bore the whole way and see an abnormally large gap between the piston and cylinder it's gona need bored out and oversized piston and rings installed.Max out of round on a kohler is .003 Fresh bore is 3.3755/3.3745 with a max wear limit of 3.3780.
But if it runs and your happy with the way it runs,no smoke or knocks then just swap her over.
Wiring should be the same.2 wires from the stator to the regulator and 1 wire from the regulator to the key switch.Use the regulator off of the 212 and hook it to the 112s wiring.

our frame should look like this. the motor should have a flat bottom.
this is what the 212 frame looks like. note the motor supports.
the pan on the 212 is not flat, it is deeper. there are two different motor pans for the 212.
a steel pan and a aluminum, the steel pan uses the two piece support, the aluminum pan uses the single support.
