I have no spark. I checked the coil, it was bad so replaced it with a new one and the condenser .
Coil wires, plugs are good. Does not have points.

She is the P220G model

Any suggestions?

Do you have the TM for the tractor? It is most likely the electronic ignition module/trigger ring buried down under the flywheel. There is a way to test the module in the manual.
