Bill,
I could not find a schematic, sorry.
Before we totally condemn the coil (that dude is pricey) I would like for you to try something (I just look back at your original post and happen to think of something).
Reconnect both plug wires to the coil, check the plug gap .035 and install them and connect the plug wires.
Check the point gap, .016 to .018 (closer to .018 is better).
Pour about 1oz. of fresh gasoline in the throat of the carburetor and leave the air cleaner off (that is better than using starting fluid). Open the throttle to about half, do not put the choke on, (that amount of gas should slightly have the engine flooded but that is ok).
Crank the engine. It may take a little more cranking than normal but it should fire and run even on one cylinder for a short time.
If this tractor quit running and has been sitting for a year or more their may be a fuel problem also. If the engine is getting fuel and the timing (point gap) is about right it will run on one cylinder (not good but it will run).
Pleas try this and let me know.
Post a Followup
