Got stuck for a week on a shutter curtain that looked fine
Had a Nikon FM2 on the bench last month with a shutter that would fire but not expose. Everything looked clean and the curtains moved. I spent days checking the slow speed escapement and mirror timing. The real issue was a tiny, almost invisible, bit of old foam sealant stuck in the second curtain's track. It only caught at the very end of the travel. Took a full 7 days to spot it with a loupe. Has anyone else lost that much time to a speck of gunk?

Wait, isn't the FM2 a vertical travel titanium shutter? I thought those curtains ran in channels, not a track with a foam seal. Could it have been a different model, or maybe some weird repair hack from a past owner? That's a brutal week over a tiny speck. What did you use to finally get it out?
