Hello, I am hoping someone can help me with my new Yashica Mat. I took off the face of the camera and I can fire the shutter when it is off the camera. When I put the camera back together, the mechanism that cocks the shutter is not aligning properly and it is unable to cock the shutter (seems to slip past it- or gets stuck and I back off so not to force anything). There is nothing that looks bent so I think I am doing something wrong in aligning something? Everything seems to work well independently. Thanks for any help.
