Idling on one cylinder. Bad stator?

Simple question....

Is it possible for a bad stator to cause a loss in spark to one cylinder?

I have an intermittent low idle issue (mostly coming down from high RPMs) and determined today that the cause is the ignition is not sparking on the MAG cylinder's compression stroke, but ok on the PTO.

I pulled the MAG cover and it smelled like burnt electrical. Also the stator is kind of black on the windings and poles.

When I tested the yellow leads, all are shorted to ground.

Previously when I was diagnosing, it tested ok.
