Free Eager Beaver chainsaw

I've run into something i've not seen before on a 2 cycle engine.I have an eager beaver chain saw and the fuel is running out of the muffler on it when I try to start it.
I've adjusted the carb (zama) to almost no turns out on both the idle and high speed and it still does the same thing. Any ideas. I've seen this on 4 cycle engines but never a 2 cylcle.

The carb needs repair, something inside is leaking.

Diaphragm pushing on needle, not allowing it to seat and fuel just keeps a running.

If you have that much fuel flowing out of the muffler, the crankcase is really flooded. In addition to the carburetor repair look at the vent on the gas tank cap. If that is plugged, the tank would build up pressure in this heat we've been having and force the fuel past the carb and fill the crankcase.
