Hi all, I imagine this will require a CLA, but wanted to pop the issue I’m having with my FM3a on here to get some thoughts. When I advanced the film, the shutter release seems blocked and will not depress. I rewound and removed the film, but this did not solve it. When I use the advance lever, it goes all the way and back, but the shutter release is still stuck. The only way to make it work is to move the slotted screw/spindle on the base plate counter clock-wise a quarter turn. This allows the shutter release to be fired. It’s almost as if the advance lever isn’t fully arming the shutter release. Is this a spring issue? Any thoughts greatly received!
