Have seen a rash of defective "new" condensers lately.
Also run this test. Before you do this at each step verify you have voltage from your ignition with a volt meter or 12 volt light. A light is better to make sure you are getting proper current flow. One other word of warning. A lot of these tractors have insufficient fuse protection from the factory. I would advise as a matter of practice splicing blade fuses into the lines and testing jumpers. A ten amp blade fuse should be okay for the ignition and testing. It also minimizes catastrophic boo boo damage.
1. Remove the distributor cap.
2. Take a tongue depressor or insulated screw driver and manually pop open and close the points repeatedly. Make sure you are not grounding the points with the screw driver when you do this.
3. If there is no spark rotate the distributor cam until the points are open. Clip a jumper wire on the external nut that connects the points to the coil. Now using insulated pliers repeatedly pop the jumper wire to ground.
4.If no spark remove the wire going from the distributor to the coil. Run the same spark test by clipping a jumper to the distributor side of the coil.
I know this is probably not necessary, but do not of course try this on the coil terminal that is supplied by the ignition switch. This will fry your jumper and possibly the ignition switch since it would be a dead short.
If you do not get a spark by briefly popping the jumper to ground it is probably your coil. It eliminates the points and condenser, but will result in a larger spark since there is no condenser to absorb the opening of the ersatz points made from the jumper.

Today's Featured Article - Restoration Story: Fordson Major - by Anthony West. George bought his Fordson Major from a an implement sale about 18 years ago for £200.00 (UK).
