Canonet QL17 - shutter lock/release problem

[brbo]

My Canonet QL17 G-III has a problem with shutter locking (and then consequently with shutter release).

It seems like it never fully cocks the shutter. The shutter also doesn't lock, I can wind the film forever. It also doesn't fire the shutter. If I help it to fully cock the shutter it will fire when I return the wind lever to original position.

I've recorded the problem in a video with my phone as I don't know if I can explain it clearly enough:



(click on the image, it should take you to flick where you can play the video)


Anyone have an idea what is going on?

Is the timer stuck?
Try dripping a few drops of lighter fluid down the timer slot.

Selftimer woks fine. In fact all speeds seem to work (if I help to cock the shutter as in the video and release the wind lever the shutter opens and closes at proper speeds). Aperture blades also move into proper positions.

According to Rick Oleson...

...this is the part that locks the winder.

And I would assume that his next picture shows the shutter in uncocked and the winder in unlocked position:

And this is the same on my camera:



The problem is that on my camera the position of this lever is the same before and after winding. Obviously the rail below this winder lock lever retracts too far back into the uncocked position. There is obviously some mechanism that should prevent that to happen after winding that is not working correctly in my camera...?!
