To sum it up:
* If the ignition trigger is on the flywheel, you'll get a spark on every crank revolution (350X for example)
* If the ignition trigger is on the cam, you'll get a spark on every 2nd crank revolution (200S for example)
4-strokes only need a spark every other revolution (at the top of the compression stroke) but the 350x method (wasted spark) keeps things mechanically simple.
