Seth Thomas A200 movement snail problem

[CopterGene]

I have reassembled the movement up to installing the snail. Everything looks good, except that the snail turns freely. I don't think it is supposed to. What have I done wrong?

Do you have the minute wheel on right? Is it meshing with the snail?

In other words, you may have it upside down. It's the one right next to the snail, with the large washer on it.
