I recently picked up a black rose and it had some cannon issues. I replaced the cannon housing and door but the rotation was off a bit. It would go to the left to the lock but only as far over as to the middle. It would not go to anything to the right at all. I started looking into it and it seems like the link was handmade and the blocks on the motor the link connects, one was welded up and. It able to adjust. The actual block that turn off the motor will adjust and I don't think it was messed with at all.

Basically what I'm trying to figure out is how far should be ration go and how can I get it to rotate the correct way. I really don't want to purchase a new motor but if that's all I have left to do to get it fixed, I will. Or if I can buy new link pieces that would work too. I just want to get this thing working like it should
