Edelbrock Fuel Pump and Carburetor

I was able to adjust the floats and test the accelerator pump. I finally have fuel coming out of the accelerator pump into the carburetor itself like it is supposed to do. However the motor still only runs when I pour fresh gas in it. I am going to assume that the fuel that is in the system now is too old, and two of the clues are going to be that the fuel has a strong green tint to it, and the smell is like a stale gas. I am going to try and empty the system out and replace it with fresh gas to see if I can keep it running.

Thanks
