Thank you so much!!! I realized what I did. It's been over year since I removed the carb cause I had a gasoline leak after cleaning for letting it sit with old gas. Connected all the hoses and could not find where this screw and bracket went. Reviewing your pic I recalled when I took this apart and pulled the carb out, one of the black caps was missing a screw (weird?!
) and replaced it. Well DUMB me that's where the screw with choke bracket belongs....
