Something else you might want to check on your Tecumseh Kyle, and that is the points push rod. If it's the original fiberglass rod, then I'm willing to bet it is swelling up with oil when the engine is hot, and isn't sliding back and forth like it's supposed to. I've had this problem with a couple of mine already. You could buy a replacement from Deere or any Dealer that might have some Tecumseh parts laying around, or if you want to go the cheaper way, cut a 16 penny common nail to the right length, round the sharp edges off the ends, and install. I haven't had any trouble with mine since. Just be careful when pulling the old fiberglass rod out, as it will more than likely be mushroomed on the cam side due to not sliding properly. I'd hate to see you break off any pieces inside the block and have that floating around in your oil pan.
