Hi - I've just cleaned the blades on a seized Konica Auto S f1.9 and all was working well until...winding the advance lever started triggering the shutter. Now I can hold the winder midway when the shutter is fully closed, but when I wind further the shutter fires. The only 'solution' is to wind to midway and fiddle with the self-timer button until there's a faint click, which cocks the shutter and holds it. The main suspect is a small lever inside the shutter at 6 o'clock (bottom centre) which doesn't return fully. I can't see what is preventing it doing so - unless I've lost an invisible spring. Is there a clear diagram I can refer to anywhere? All advice appreciated. Many thanks.
 
A good question, are you sure you haven't trapped something during reassembly? Also, form own interest, did you disassemble the aperture blades themselves?
