The large hole in the tank brings a line from the filter to the upper carburetor fitting. The lower carburetor fitting goes to the primer inlet (which is found by plug and try). The short line from the tank goes to the outlet of the primer. With fuel mix in the tank, try one of the ports in the primer with the line from the carburetor. If correct, the primer bulb will fill with fuel--otherwise, try the other primer port and see if fuel will come into the bulb. This may take over 6 pumps if the carburetor is empty of fuel. Did you check the fuel filter for plugging? If it was ok, and with new lines, fuel should pump into the primer provided the carburetor is not plugged itself. If the problem seems to center on the carburetor, be sure to check the diaphragm in the lower chamber for flexibility--no holes or cracks. Also, there is a very small filter screen in the mid-body section that may be plugged. Use spray carburetor cleaner to clean the carburetor inside and out. When you get fuel to come into the bulb, the short line from the tank goes to the empty port. Hope some of this helps!

Who connected these hoses? the normal routing for a machine with a primer is like this, the fuel hose from the tank with the filter on the end goes to the carb fuel inlet nozzel ( not to the primer ) nearest to the pump cover ( cover on carb held with one screw ) the pipe from the metering side of the carb connects to the shorter nozzel on the primer bulb ( suction side ), the longer nozzel on the primer ( pressure side ) connects to the pipe going back to the tank, just remember the primer pulls fuel from the carb,into the bulb, and pushes it back into the tank, it is not actually a primer it is a purge. because it is connected this way it is impossible to flood the engine no matter how many times the bulb is pressed.
Let me know if it starts and runs.
