M151-A2 warm engine carburetor fuel flow

This video will demonstrate the fuel flow into a M151-A2 fully warmed up (160F) engine as well as demonstrate that pumping the gas pedal on a M151-A2 Army jeep does not add fuel into a carburetor only the engine's pistons up and down movement creating vacuum pulls the fuel from the carburetor float bowl into the engine. At the end of the video when I turn off the ignition thus turning off the engines ignition (spark) you will see how the engineer designed the Zenith carburetor to allow the final few engine piston vacuum pulses with no spark at the spark plugs to pull fuel into the carburetor to better aid the next engine startup.
