The emulsion tube might be pressed in on that carburetor. 99% of the time there's some deposits built up from old gas and that's why it doesn't run / doesn't run well. Use thin wire or a carb cleaner kit or a torch tip cleaner kit to poke the junk out of all the parts you can remove/access, and use a can of carb cleaner to spray through all the channels you can't otherwise access.
