As said earlier, you should flush the shutter and focusing helical of all of the spray lubricant. Lighter fluid (naptha) will do this, and it will take some time for it all to dissipate (evaporate). You should remove all of the lens elements before you do this.

You also should clean the helicals and regrease them. Also, carefully clean all of the lens elements.

This is a unit-focusing design, so if you remove the shutter from the camera, you will need to reset infinity focus (collimation).

The Solinette II is one of the simpler and easier cameras to service, because it doesn't have a rangefinder.

If you are really interested in camera repair, you should pick up Thomas Tomosy's books (search You will need proper tools to work on cameras. Screwdrivers, spring hooks, spanner wrench and forceps and tweezers -- to start.

Working on SLRs is a more complex process, and I would be very careful about trying to adjust the shutters in these cameras without the proper knowledge and equipment.

However, for most cameras with leaf shutters, it's not terribly difficult, and you'll be able to pick it up. Start simple, be careful and take your time.

Don't gouge parts. Use the correct-sized screwdriver for the screw. And be careful about your work.

By the way, I'm also tackling restringing the meter on an SRT 100 after the string snapped. Ugh.
