This! How long did you crank the motor before giving up? If the fuel line is empty (and it will be if the car sits for a while), it will take a long time to get fuel to the carb. I'll probably get yelled at for saying this, but a couple of squirts of starting fluid into the primary throttle bores will get the motor running, and that will fill the fuel line quicker than anything. Other than getting an electric fuel pump, that is.
