Non governor side flywheel Originally from a 1HP Aircooled Tom Thumb engine. I believe it’s the same flywheel on the hopper cooled 1HP famous as well. Flywheel has no cracks or breaks. The hub on the inside does have a few bumps/rough edges which could be dressed up with some sanding in sure. Please see all pictures for the absolute best description. Keep in mind this item is not new. It’s a used item that is over 100 years.
