From your vid, it would appear that the engine spins too freely, and offers no resistance,as if there is no compression.

I concur with rohmell. It shouldn't spin over like that if it's got compression. Possibilities are stuck valves, missing spark plug, or a holed piston.

Alright, so it doesn't have compression, it does backfire though. I was thinking about cracking it open to check out the piston rings maybe.
