There are two sets of points opposite each other on the armature plate and two condensers. I would think that each set of points/ condenser would be wired to one ignition coil/ one spark plug to fire once per revolution, instead of combining both sets of points to each ignition coil/ spark plug. Each cylinder will fire if I remove the plug cap from the other cylinder. The manual doesn't say. It's the only reason I can figure why both cylinders won't run the same time is the spark is at the same time, once per revolution. The sparks look a little different. One spark is brighter and lasts longer than the other spark plug. I am trying to investigate if a bad condenser would account for this and delay the spark so they would fire about the same time. The above was wrong. Upon removing the flywheel, it has CDI not points.
