PRONTOR-S shutter doesn't stay cocked

[Pancolart]

This is a bit urgent since i am repairing Isolette, already sold . I wanted only to clean it since longer times were unuseful but now problems are much bigger. Shutter doesn't stay cocked.

I don't know what keeps it cocked. I also unscrewed two parts (on photo), but no metter how i put it back it doesn't help. Before this accident happened i was also pushing different parts with screwdriver and might have cause the damage - anyway the shutter now fires very smoothly, so initial problem is resolved ;(.

Could someone please show me on the photo where colud i have made mistake - which parts play role in keeping shutter on place when cocked. Should i do that with two removed parts?



Two unscrewed parts. Right one goes under the left.

Thank you in advance,
Jure

Resolved! The tiny end of the part showed by red arrow was bent down. That's the stoppage. The other two parts on photo above are placed in the hole right near. They take care of B (time). Now this Isolette fires like charm at all times!



Now i have to do something to releave my painful back and neck .
