Did you happen to run the tractor more then usual with heavy choking? I would check the spark plugs to see if they are fouled with black soot. In particular look at the internal center porcelain cone that the electrode comes up through. If they have black soot on them that is conductive and the spark will ground out through that soot coating. Spray some carb cleaner on it and use a hand wire brush on it. Maybe do this a couple times to each one blow it off with compressed air. Then for a final touch take a propane torch and heat up the electrode end focus the flame down towards that porcelain cone. It is okay if the ground electrode get red hot for a bit. After it cools another short blast of carb spray and compressed air. Re-gap and install. No one has came right out and said it but by increasing the gap for the spark to jump causes a greater saturation of electrons in the secondary coil winding, in other words it raises the spark voltage when you make it jump that gap. So in the case of the fouled plugs, the higher voltage will jump the normal spark gap instead of shorting down the fouled porcelain.
