  • How does the throttle work on a carburetor?

  • Beneath the venturi, there’s a second valve called the throttle. The more the throttle is open, the more air flows through the carburetor and the more fuel it drags in from the pipe to the side. With more fuel and air flowing in, the engine releases more energy and makes more power and the car goes faster.

  • How does a carburetor work?

  • The vacuum moves around the carb and gas is pulled through different jets and is vaporized as it is pulled into the combustion chamber. Different jets and air passages in the carb are controlled by different throttle positions. At certain throttle positions, some of the systems will overlap.

  • What does the choke do on a carburetor?

  • The carburetor has two swiveling valves above and below the venturi. At the top, there’s a valve called the choke that regulates how much air can flow in. If the choke is closed, less air flows down through the pipe and the venturi sucks in more fuel, so the engine gets a fuel-rich mixture.

  • How does a car engine work?

  • The drop in air pressure creates suction on the fuel pipe (right), drawing in fuel (orange). The throttle (green) is a valve that swivels to open or close the pipe. When the throttle is open, more air and fuel flows to the cylinders so the engine produces more power and the car goes faster. The mixture of air and fuel flows down into the cylinders.
