I love this. Great mystery of life.

Hub doesn't work if assembled wrong, works when assembled correctly. Who would have guessed?

(sorry, I couldn't resist)

Anyway, it's a reminder that freewheel clutch pawls have to be oriented to engage the ring they work with (on bikes, that's clockwise looking from the right side). The tip also has to be such that it acts like a snow shovel and catches and locks the pockets in the ring, rather than skiing over the tops.
