Man, that is awesome! Nice find, Rj!

He'll of an idea......would like to see one in action.

That's pretty cool. Although I'm sure it's tested and quite sturdy, that circular/wobbly reciprocator movement gives me the "heebie jeebies" though.

Next...where can I get one to retrofit into my S Series ??

It is a wobbler

Wow! An interesting variation of the radial engine with far more moving parts. I wonder how that wobble plate is lubricated to keep from wearing out. Of course rather than a heavy crank shaft used to convert linear motion to rotary motion you have a heavy wobble plate instead with a lubrication problem, but is is probably solved by the 2 cycle way the engine runs and we all know how well they ran until emissions killed them.
NEAT!

Wow that thing is cool.
