Question: Why Do I Have To Pour Gas In Carburetor To Start?

Why do I have to pump the gas to start car carburetor?

Why is my carburetor not getting gas?

No fuel at your carburetor can be caused by many things. It could be a simple issue like a fuel filter plugged so tight that no fuel can pass through. Another logical cause could be the fuel pump. A hole in the fuel line on the tank side could also cause the fuel pump to suck air instead of fuel from the fuel tank.
