The CEVY 2 barrel carburetor is a downdraft carburetor that is used on many General Motors vehicles. It is a simple and reliable carburetor that is easy to maintain and adjust. The carburetor consists of two main barrels, which are controlled by a single throttle valve. The primary barrel is responsible for providing air and fuel to the engine at idle and low speeds, while the secondary barrel opens up at higher speeds to provide additional air and fuel. The carburetor also has a choke, which is used to enrich the air/fuel mixture when the engine is cold.
Here are the main components of a CEVY 2 barrel carburetor:
* Throttle body: The throttle body is the main housing of the carburetor. It contains the throttle valve, which controls the amount of air that enters the engine.
* Venturi: The venturi is a narrowing of the air passage in the throttle body. This causes the air to speed up and create a vacuum, which draws fuel from the fuel bowl.
* Fuel bowl: The fuel bowl is a reservoir that stores fuel for the carburetor. The fuel level in the fuel bowl is maintained by a float.
* Jets: The jets are small orifices that allow fuel to flow from the fuel bowl into the air stream. The size of the jets determines how much fuel is delivered to the engine.
* Choke: The choke is a valve that restricts the airflow into the carburetor. This enriches the air/fuel mixture when the engine is cold.
* Idle speed screw: The idle speed screw adjusts the amount of air that bypasses the throttle valve at idle. This controls the engine's idle speed.
* Mixture screw: The mixture screw adjusts the amount of fuel that is delivered to the engine at idle. This controls the engine's air/fuel mixture.
The CEVY 2 barrel carburetor is a simple and reliable carburetor that is easy to maintain and adjust. It is a good choice for anyone looking for a reliable and affordable carburetor for their vehicle.
