George,
 
this flywheel is my design, it is steel = with the=20 cut outs for balancing. The steel section is 14mm thick, and the ring = gear is=20 250mm diameter, coming off a Metro Geo engine.
I calculated my hp from fuel flow using = a BFSC of=20 .5 . May be a little optimistic. Mixture was slightly rich at the tests. =
I am running now a Mikuni VM44 = carb.
