Zorki 6 - second curtain not working

[franciscojhh]

I was given as a present a Zorki-6 in OK cosmetic condition but with problems in the shutter, such as second curtain not closing completely or closing too slowly.

I assumed that the camera was OK, only needing some cleaning and lubricating, so I opened it (following the instructions of http://www.rangefinderforum.com/foru...ad.php?t=45110). However, now the second curtain does not close after the first one opens. I can cock the shutter and the first curtain retracts as it should, but the second curtain does not move.

What can I do?

Might be the roller spring for the second curtain has come loose or is broken. Or maybe it's dirt in the channels.

You mean, one of the springs that can be tighten at the bottom of the camera (after taking away the bottom plate)? I don't think so, because I never took away the little screw that keeps it tight.
