That is good advice from Paul on checking the rotor for rotation could be a stripped gear.

Here's a step by step for troubleshooting for no spark:

Be sure distributor cap is dry & clean.
1. Is there battery voltage at the coil? Use test lite or volt meter.
2. Is there battery voltage at the points? Use
test lite or volt meter.
3. Remove distr. cap, rotor & points cover; remove coil wire from distr. cap & hold within 1/4" of a good ground.
4. With points closed and ignition switch on, snap the points open and closed a few times & check for spark at the coil wire end.
5. No spark: may have dirty or burnt points, bad condenser or coil. Coil wire must be attached to + on coil if battery is + grounded.

If this tractor has been converted to 12 volts and uses a ballast resistor they are known to cause problems. One last thing is to check for voltage at your ignition switch. Check for input voltage to the switch and with the switch on check
the output side for voltage. If you have voltage on the input side only, use a clip lead and jump
past the ignition switch and see if the engine will start. Hal
