Nice way to waste a couple of perfectly good Tee Dees.

I think this was part of a lot of "twin" engines that was on ebay a month or two ago.

Look closely as the side of the engines. There's a bar(thin aluminum sheet maybe?) that is connecting the lugs of each engine. Holding them together maybe?

There's possibly one good TD there. Depending on how the crank was made.  Maybe two if they aren't even connected.lol!

Why do people post things up for sale without enough pics. It still has the problem of running two pistons on one crank, does it work and how was it done....

To scam you. I honestly can't imagine how it would work.

It would probably work if the crankshafts were timed correctly. As in both engines fired at the same time. I am assuming the rear engines crank is "keyed" into the crank of the front engine.

Still though, is it worth it? Maybe to some.

You are correct! Didn't see that. Seeing as it doesn't share a common crankcase it would work if it was 180 degrees out.

Hey... I just thought of an idea. How about doing a twin with a friction 1-way bearing. These are commonly used in RC Helicopters

I get the credit for mentioning "ball-bearings".......... "What do you mean; I've exceeded my credit limit?"
