Carburetor leaking

[terabytemc]

I cleaner up the zenith carburetor put in new gaskets everything was running great, went to start it 2 weeks later and it won't start keeps dying like it was not getting any fuel, I added gas thinking gravity feed low on gas, got it running backed it out got 10 feet and died would not start again. Now when I turn on the gas valve gas is pouring out of the carburetor. Any thoughts?
