Manual choke carb issue

[LSUMurse]

The choke on the carb does not want to release when I push the button on the dash back in. It stays out whether the truck is up to temp or not (not sure if that makes a difference). It's not that much of an issue for me, I can get out and manually push the lever the choke is connected to back into position, but the wife drives the truck now and then and I don't want her to have to go under the hood if at all possible. She's a girl, they mess things up!

I don't know much about carbs. Is there anything in particular I should look for? Lubricate? I sprayed the carb down with carb cleaner a few months ago, does it need another hosing off? Are there springs or something mechanical I need to check? I'm planning on replacing this carb within the next year, so I don't really want to rebuild it.

I have a stock 307 with a HEI distributor and the stock 2 bbl carb.

Thanks,
