I have two Zorki 4's, the one I bought from Rick which works perfectly, and another body someone gave to me because the shutter doesn't fire.
With the back off, it's obvious that the shutter doesn't fully return to firing position after the rewind release is returned to normal and the gears don't rise high enough to engage the film sprockets.
I've messed around with it some and occasionally it'll pop back up. At any time I can pull it up with a cable release. So the camera's nearly functional, except for this bit of sticking. Once up, it shoots fine for the entire roll. But after a film change, here we go again ...
Does this sound like something fairly simple to fix? Can it be easily lubed or cleaned or something so it pops back up when the rewind release is turned back to normal?
The body is in pretty nice condition and I'd like to turn it into a user.

Gene:
Sounds like a sludge problem. Might be solved with a judicious application of lighter fluid in the proper sponts--but be very careful to keep the fluid away from the curtain area as it will dissolve the glue holding the curtains and tapes.

Thanks Wayne. I caught a semi-related thread on RFF that said something about a tension screw existing underneath the film-advance knob but I wasn't sure if it was related.

Gene, the same thing was wrong with the 4 when I got it. the main reason it was such a deal. I cleaned it with Ronsonol and it worked just fine as you well know.

Adjusting the spring tension on a FSU camera with a slow shutter usually doesn't solve the problem. The shutter is slow because it's gunked up. If you just tighten the springs it may be faster but the speeds will be erratic.

Hi Gene,
Canadian Tire, Home Hardware, Walmart, I believe they all carry Ronsonol. Just look for the yellow plastic bottle in the lighter fluid area usually in the paint or chemicals section.

In the UK, all lighter fluids, so far as I know, comes in tins with a flip-up spout. There are various brands about, but I think they're all naptha. I've never found any difference betwen any of them for cleaning and disolving old grease.

Just be careful. A leeetle bit of the stuff goes a long way. Keep it away from the area of the rangefinder. It can migrate in there and cause big headaches.

Gene,
I find it difficult to control the flow of the lighter fluid directly from the can.
You can buy large hypodermic syringes with blunt needles at Lee Valley. They call them Glue Syringes. Five syringes and ten needles for $9.50. They should last forever. Page 160 of their latest catalougue. They are also good for glue if it is not too viscous.
There are three stores in the GTA.
Lighter fluid is available in almost any store that sells cigarettes.
A diabetic on insulin could give you plenty of used hypos.

You can also use the ink refill hypos from a printer refill kit or simply squirt a bit of fluid into any bottle cap and use the fine end of a toothpick to dab the fluid where you need it.
