shape of the Venturi tube looks much like that of an hour glass. The air cleaner cleans the air of dirt and other unwanted substances before it enters the engine. There are many little jets that accept the gasoline from the float chamber. The first jet, the pump jet, is located in the first wide section of the carburetor. The second jet is the main jet. It releases gasoline into the narrow section of the Venturi tube. When the tube widens back up, that is where the idle jet would be found. The decrease of the pressure in the narrow part of the tube, creates a vacuum that sucks gasoline from the main jet and into the Venturi. (Fuel) The choke valve controls the amount of air that enters the carburetor. Between the air cleaner and the Venturi tube is where the choke valve is located. When an engine is cold, it needs more gasoline and less air. A warmer engine needs more air and less gasoline. The choke valve controls all of that when the engine is cold or warm. The throttle valve regulates the amount of fuel-air mixture that enters the intake manifold. The throttle valve is located in between the main jet and the idle jet. The fuel tank is a tank that holds the gasoline. The gasoline is sucked from the fuel tank and into the carburetor to make its process through the engine. (Fuel)There are many different parts that make the car run. One of the major components that allows the car to run is gasoline. The gasoline makes its way throughout the whole system. Without gasoline, the carburetor would not be able to keep up in good shape. The metal would dry out and the carbon in the gasoline could not create a power source.The ignition starts the car. To start the car, the driver puts the key into the ignition and turns it. This closes the switch which allows electricity to flow through the battery to the electrical starter. (Under)The transmission is another major necessity of the engine. The transmission can adjust...
