I saw this at work today. It is on a gc190 e start push mower. Looks like it can go right a predator and give you a charge coil for gauges or a headlight with the factory flywheel. It is built into the coil. Thought I would share my find.
Any Honda HRX217 mower with e-start (type VKA I think) made within the last 7 years should have this coil. Ill see if I can get a part # from our database tomorrow
