Standard .049 MkII but with a pin on the thrust washer and an added mount riveted on the bottom mounting hole.  The pin is solid and looks like an interuptor for an ignition, but isn't.  Boat engine maybe with some sort of a drive shaft? Wrap a string around it and pull???

Dedicated engine out of a Wen Mac model, or home built?

lol, i had to go to my web site to look it up, i forgot what it was called, i was thinking Flex-O-Matic?

"Flex-o-Power-Ring", First appeared in 1956 on the Wen-Mac engine Mk. II model 3 as a option to the pull cord starter used on entry level models through the 1961 Mk III series. It's a large O-ring didn't work real well, maybe get a couple rotations at best.

Wow Mark, You came up with that quick.  Your forgiven for not including the taper crankcase transition date on your Cox engine info picture.

I can't figure out what the black tubing O ring? wound through that mount fitting does though.

I got it now, you slip the unsecured O ring end around the pin, wind and let it go. Dumb, but interesting.

I am just wondering what imbalance that little pin may have caused to the engine revving at 15k?

lol, I do think Flex-O-Matic sounds better than "Flex-o-Power"!

The idea was to slip the O-ring over the pin and rotate the prop in the opposite direction, not really sure why the Corsair had that crossbar under engine unless it was to hold O-ring in place and make it easy to grab?

Interesting, I don't know much about the Wen Mac's but that little sharp looking sheet metal bracket looks like it would cut that O-ring in short order. Huh... (Bandit)

Mark, you posted this pic to another thread before, but I couldn't find it. Does the "scar" on one of the crankcases mean something else besides a manufacturing glitch? My never-run Black Widow has a similar pattern on the underside of the crankcase.
