Cam, if the leak is bad you probably have plugged air cleaner, or plugged idle passage vent, or bowl vent restriction.
~If the needle isn't too loose, probably a little Teflon pipe sealer [NOT Teflon tape] on the threads will do it. If the needle is loose or the leak is bad then using a small "O" ring or two between the needle & carb casting will stop your leak...

Perhaps the spring that loads the detent ball is weak. A strong spring will load the threads on the idle screw so that leaking is minimal. A weak or missing spring will allow the threads to rattle freely & allow an air leak.
