From your video, it looks to me like the idler gear is turning clockwise. See in the picture from Laitch it should be turning anti clockwise. The post by Olaf has a link how to fix it.
The earlier posts say the sprag clutch only spins free in one direction meaning it seems to be performing correctly. The usual issue is that it can spin in both directions.
