Might make a good lil mini bike or go cart motor. I have used some small bore/cc 2 stroke motors on mini bike frames. Some bigger ones on go carts also (like wha you have). don't toss it, for $10 if it runs than you cant go wrong. If it don't run than I am sure you will get more than your $ back in parts if you take it apart. but if she does run , than slap her on some type of frame and I guarantee you will get your $10 worth out of it before she blows up

Or you could run it like it is (no pipe) and possibly tick off your neighbors

All in all you have a decent learning tool for $10 ,,really. Take it apart,,, look at how things work and make sense of them.
I would buy that thing all day long for $10 ..
