carburetor

A carburetor (also spelled carburettor or carburetter) is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the Venturi tube in the main metering circuit, though various other components are also used to provide extra fuel or air in specific circumstances.
Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, but carburetors are still used by some small engines (e.g. lawnmowers, generators, and concrete mixers) and motorcycles. In addition, they are still widely used on piston engine driven aircraft. Diesel engines have always used fuel injection instead of carburetors, as the compression-based combustion of diesel requires a greater precision and pressure of fuel-injection.

    Engine Carburetor issues

    My 82 CJ7 was having issues with starting after it sat for periods of time longer than a half hour. I had to continually pump the accelerator all the way to the floor in order to get it to start. I believed it to be an issue with the carburetor which I have replaced several times prior, so I did...
