High Standard pistol trigger not 'resetting' after firing

I've had a High Standard 107 Supermatic Trophy .22 pistol for many years. When I recently went to fire it, after not using it for a while, I find that the trigger will not 'reset' after firing. It is 'sticking' in the fired position. If I give the trigger a slight push forward, I can feel it reset, and then it will fire again. This happens after every shot. I've taken off the grips, cleaned (it wasn't really dirty) and lightly oiled the sear bar assembly, etc. but the problem persists. Thoughts?
 
If that does (not) work .. take off the grips, hold it with rubber gloves near the end of the barrel and pour several saucepans of boiling water over and through the guts of the pistol. Shake any residual water off and let the now hot metal dry. Then using a very light gun oil like G96 spray ... very lightly lubricate.

Probably just a bit of grease that turned gummy over the years.

You can also try spraying it with engine degreaser and then giving it a good cleaning afterwards..
 
It was working years ago and just sat and now it doesn't work... I don't think a screw needs adjustment...It really sounds like the sear return spring is gummed up with dried lubricant. If so it will require proper cleaning and free movement should be restored. I would not go adjusting any screws until you clean this return spring and test it.

Pretty funny (more 'smell', than 'ha-ha') funny how folks seem to default to "It's Broken!" when something that worked when put away, doesn't when dug out of storage.
 
I have seen these where the trigger pivot will rust and trigger get sticky, you have the trigger bar little spring in there yet?
Take the grip and side plate off and carefully #### it and see if the trigger bar engages the sear, don't lose the flat v shaped spring.
I have pictures of the parts, but not on the computer at the moment, I would not mess with the trigger adjust, unless it is way out of adj.
