What does the bowl do in a carburetor?
Mounted on the side of the carburetor is the float-feed chamber, or “bowl,” which is essentially a miniature fuel tank fed by the main fuel tank. Because the carburetor can’t use fuel under pressure, whether delivered by a fuel pump or gravity, the float chamber is kept at atmospheric pressure.
Why is there no fuel in my carburetor bowl?
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.
