Did you make sure the bearing only turns one way? Do you hear anything while turning the motor over? Take a look at my picture.. The spring should be pushing that small pin into the starter shaft. If you rotate the motor backwards with the flywheel, you should hear it click.

Now, if that seems alright, make sure that bearing only spins freely one way. They are a common problem, and when they let go, they either lock up, or spin freely either way. You can try cleaning the one way bearing with some denatured alcohol. If it spins both ways, or is locked you need a new one.

See when when the bearing is on the starter shaft it still spins the shaft just not catching, not turning the motor over.

Does it spin both ways? If so, clean it with some denatured alcohol, and if it still does, it's time for a new one. They are designed to freely spin one way, and lock in the other direction. This allows the starter assembly to rotate freely so the motor isn't pulling it along, but also allows you to start the engine. If it is slipping, it usually means it's shot, but a cleaning might help it.

the bearing does only spin one. its beyond that. The starter shaft spins but doesn't spin the motor over.

Thanks for all the help everyone. I finally got it worked out.
