( Brand: Carter ), ( Manufacturer Part Number: 352S ), ( Type: Carburetor )
The Carter W-1 1-barrel carburetor, specifically the model 352S, is a vital component of the 1937 and 1938 Pontiac 6-cylinder engines. This carburetor is a testament to Carter's long-standing reputation for producing high-quality fuel delivery systems.
The Carter 352S W-1 carburetor is a single-barrel, downdraft design, which means the intake manifold is located below the carburetor. This layout allows for a more direct path for air and fuel to enter the engine, improving combustion efficiency. The 1-barrel configuration is ideal for smaller engines, like the 6-cylinder powerplant found in the 1937 and 1938 Pontiac models.
The barrel of the carburetor is constructed from high-quality materials, likely aluminum or brass, to ensure durability and resistance to corrosion. The barrel houses the main fuel jet, which delivers fuel to the engine under vacuum. The jet size can be adjusted to fine-tune the fuel-air mixture for optimal engine performance.
The carburetor features a manual choke, which is activated by a lever on the driver's side of the vehicle. The manual choke allows the driver to control the amount of air entering the carburetor, which in turn affects the fuel-air mixture. This is particularly useful in cold weather, as it allows the engine to start easier by enriching the fuel-air mixture.
The Carter 352S W-1 carburetor is also equipped with a float bowl, which stores excess fuel. The float bowl level is controlled by a float that rises and falls with the level of fuel. As the fuel level drops, the float falls, which triggers the fuel pump to draw more fuel into the bowl. This ensures a consistent fuel supply to the engine, even during heavy acceleration.
The carburetor is mounted to the intake manifold using carburetor mounting bolts. The intake manifold is connected to the cylinder heads, creating a path for the fuel-air mixture to be drawn into the engine's cylinders.
In summary, the Carter 352S W-1 1-barrel carburetor is a crucial component of the 1937 and 1938 Pontiac 6-cylinder engines. Its downdraft design, 1-barrel configuration, and manual choke make it an efficient and reliable fuel delivery system. The construction materials and design features ensure durability and ease of adjustment, making it a popular choice for classic car enthusiasts and restorers.
