Or were the pawl wheels disassembled at some point and reassembled incorrectly? (I doubt it as I thought these wheels were not meant to be disassembled, but I know from personal experience that relative beginners do all sorts of things out of ignorance!) It's not possible to tell with any confidence, but it kind of looks like both pawls are set to turn the bottom half anticlockwise. If that were the case, installing the rotor would make it impossible to turn in one direction and ineffective in the other.

I definitely didn't take those wheels apart, like I explained, all wheels will spin in both directions when the rotor is off but the Drive wheel won't turn when the rotor is on

There's something not right but I can't make it out from the photo.

This is what a good one should look like.

And here's the one with the pinion.

[GPrideaux]

Check the operation of each pawl wheel individually. Holding the larger wheel stationary, you should be able to turn the smaller wheel in one direction only. The direction should be different for the two wheels. The one without the pinion should turn freely anticlockwise, the one with the pinion should turn freely clockwise.

I might have that backwards ... it's hard to visualise ... but they should turn freely in just one direction, and they should be opposite directions.
