The carburetor was once one of the most important pieces of technology in the automobile.

Using little more than airflow, pressure differences, jets, floats, and mechanical linkages, it transformed liquid gasoline into the fuel-air mixture that powered millions of American engines. For generations, mechanics could tune, rebuild, and repair one with ordinary hand tools.

Then electronic fuel injection changed everything.

This automotive history documentary examines the engineering behind the carburetor, including the venturi principle, float bowls, throttle plates, chokes, four-barrel carburetors, feedback carburetors, and the legendary Rochester Quadrajet.

We trace the competition between carburetors and fuel injection from Chevrolet's 1957 Fuelie Corvette through the emissions era, three-way catalytic converters, electronic engine controls, throttle-body injection, and the final carbureted General Motors engines of 1990.

And the story doesn't end there. Carburetors survived much longer in NASCAR, aviation, lawn equipment, generators, and the classic-car community—proof that simple mechanical technology can remain useful long after the automotive industry moves on.
