Carb choke not releasing/cutting off

This is technically a Poulan Pro made by Electrolux at the time.... However I'm not finding a sticker on the engine for parts. So... that's why I'm here. In the picture as you may know there is linkage to the carb from the throttle from low to high range. Once you push the throttle past max it pushes on the choke. The problem is the choke doesn't spring back or move at all when the throttle is reduced from the choke position back to max throttle. It moves by hand very easily and stops wherever you leave it. I don't see where any other pictures I've found on the net have anything connected via spring or rod to the choke flap. Any help or pictures pointing me in the direction of what to do would be greatly appreciated. Also where I could find the spring/part at would be nice! :help:

No sticker on the surround of the engine cover for model or serial

This is the sticker under the seat for the actual lawn mower model. Hope it helps.

Look around long enough and you might answer your own question.... Which leads to more questions! :ROFL I see a return spring in this pic since it's pretty much exactly what I have. With that being said... Where did the one on mine go? How do I find just that spring? Kind of a head scratcher? :dunno:
