Cutaway model of a vertical twin carburettor system mounted on a solid base. This compact trainer displays the internal structure and operation principle of a twin-barrel carburettor used in older petrol (gasoline) engines. The sectioned view reveals the fuel mixing chamber, throttle valve, choke mechanism, float chamber, and venturi design. This automotive education tool is used for visual demonstration of air-fuel mixture regulation and delivery in internal combustion engines.
