Lionel 3435 Aquarium Car problems


I have a 3435 Aquarium car that vibrates just fine, but won't revolve.

Both sprockets revolve freely, I've tried increasing and decreasing the tension on the spring with no luck.  There is a loop and a half of cord going around the drive sprocket.  Here are pictures of the unit with the film strip removed along with a video clip.

If anyone has advice on this it would be greatly appreciated
