i was given these 2 engines on Sunday. no marks or casting #'s.
10" flywheel with fan spokes and an oiler port for the piston.

the one with the mixer has a bronze casting for the crankcase cover/outer
support, vertical mag mount, flyball governor, copper gas tank, internal
cam gear for exhaust pushrod. the crank turns 2.5 rev to 1 on the large
gear.
the small pully has an inner groove with a hook for a starting rope.

the partial engine has a cast iron horizontal mag mount, etc.

both base castings have the same 3 bolt mounting pattern for something.
i'm wondering if this was used as a forge blower engine
running the fan belt on the flywheel perimeter?

thanks, marv
