If you have any knowledge of gasoline engines, you would know that a carburetor is an essential piece in making an engine run properly. The object of a carburetor is to mix gas with air to the proper ratio and supply this mixture to the engine for combustion. Approximately 10 milligrams of gasoline is needed for each combustion stroke. If someone tells you your engine is running lean, it probably means that you do not have enough fuel mixing with the air. But if there is too much fuel mixing with the air, it will run rich. All of this can be fixed with simple adjustments to parts on your carburetor. The theory of carburation is based off of the Principle of Bernoulli. This principle said that as the velocity of an ideal gas increases, the pressure drops. This is just what happens in the carburetor. In other words, as the pressure drops more and more within the carburetor, the velocity of the air increases, because the air in the high pressure wants to escape faster and faster into the low pressure. This loss of air pressure happens within the venturi. Standard air pressure is somewhere around 15 pounds per square inch. As the air from outside moves inside the engine it passes through the carburetor and picks up fuel on the way. There are many pieces that make up a carburetor. We will not get into the nitty-gritty details but cover the basic working parts of a basic carburetor. Basically, all a carburetor is, is a tube that begins to taper down creating a vacuum.
