Okay, a bit more digging finds me 611094 -- Flywheel (W/Ring Gear). This one seems rather expensive at ~$200 to $250. This model has a bunch of magnets for the charging magneto. I do not need any of the charging system, only the gear teeth.
I gather that essentially the same flywheel was used in several 8 to 14 HP models. I would be looking for one originally for a 120V electric start snowblower or something -- with no battery or charging system.
Thanks
