You can see from the diagram #jeffc posted where the override stop goes. I just want to emphasize that it is not supposed to touch or stop the armature. The cradle arms (drive pawl) at the end of the armature need to fully engage the gear wheel (ratchet), otherwise the stepper will not work correctly.

The override stop is just supposed to prevent the cradle from digging too far into the gear wheel after making a full engagement. It's really difficult to set this stop properly on AS relays that have a printed circuit board on both sides of the relay.

If you can't get the override stop adjusted exactly, just make sure it's not touching the armature when the cradle arms are fully engaged with the ratchet.
