Rcimp,
You keep mentioning the carburetor isn't filling with fuel...how are you determining this? Short of pulling the top off, the only way to determine that would be a no-go on the accelerator pump squirt, and that test isn't iron clad.
If you can blow through the carburetor fuel inlet, and the fuel pump is squirting fuel, my guess would be the carburetor has to be filling with fuel.
The other thing to keep in mind is the suction side of the fuel pump. If it's plugged, even a good pump won't function. The fuel pump won't put out any more than a restricted inlet would allow.
