you can try some carb cleaner around the rim then warm water soaking will drop it .. anyway get the carb out to refurb it and check the float etc… you will need to clean the inside metallic filter also by soaking it in carb cleaner followed by air blasts .
sometimes after soaking a gentle wack with a small piece of wood will loosen it of gasket … work slow…. be patient nothing is holding it in but dried gunk
