while i was reading one of the small engine books i own *trying to figure out some thing very simple* any ways i was looking at the flywheel when i got an crazy idea. If I take a fly wheel

and had a friend who welds like a Pro take some square peaces of metal or aluminum if the wheel is, have them welded on every other port on the flywheel and grinded flush to the side. Then form some type of band that wraps around the wheel and is enough to cover up the ports on the rotor and cut holes into the band so it will act like a stator. Now it gets even more tricky should it be mounted to the old engine or on to a high torque stationary buffing wheel. Now in theory it should work if it stays balanced and if the vains on the flywheel catch the air and pull it towards the ports.
but that just in my head and I may just try it since I have allot of extra parts in the shied.
and feel free to tell me it wount work just gives me more to work on in my head. and if your self feel like trying this go right ahead!
