Did you do anything else to the tractor, wiring wise? Same ignition switch?

 

First thing I would do is disconnect the kill wire from the coil and see if you have spark.

Bench test the coil?

 

Continuity test the wiring?

 

Check and clean the points?

There are no points, no bench test. Manual has you check everything else then replace the module.  Two modules no spark I agree with ZXT  make sure the kill wire isn't grounded

Did you replace the spark plug with a new Champion? If you did, try a different plug. Several of us had new Champions that would not fire.

Clean the flywheel magnets and tighten up the air gap.

I am not sure what ignition you have, but you might check my web site, www.enginesandmagnets.com, if it is a Solid State Ignition like on most HH120s.edstoller at earthlink dot net. I have also been working on a new ignition made from a GM LS2 ignition coil and a modified GM PC2 crank sensor that looks very promising.
