Carburetors are responsible for supplying the engine with fuel and air, which mix together inside of it. They are used on most engines that use gasoline as a fuel source. The carburetor has many parts that need to be in good condition for it to work properly. Some of these parts include air bleeds, discharge nozzles, floats, dust covers and heat shields.
