As the fuel level rises , thefloatalso arise , and when it reaches a certain point , it activate the phonograph needle valve to shut off the flow of fuel into the carburettor . The needle valve is what prevent the carburettor from being glut with fuel .
If theneedle valvebecomes stuck in the closed emplacement , it will not be capable to shut off the flow of fuel into the carburetor when the fuel degree rise .
In addition , this can cause the fuel to cover to hang into the carburetor , even when the float has give its maximum pinnacle and is assay to close off the fuel supply .
