Remove it, remove the bowl, the float, float needle, and all of the jets, and spray carburator cleaner through ALL of the ports. (You should see it come out some where else.)
Note the idle, or pilot jet may have holes along the side of it, make sure they are all clear.
If the carburator is too gummed up, then the parts need to be soaked in a chemical called "hydro seal." This is available at auto parts stores. Keep in mind that this chemical will eat gaskets, and plastic.
