The Carter WG Series 2-barrel carburetor, model 2207SB, is a classic automotive component designed to deliver optimal fuel-air mixture for the powerful 1955 Pontiac 287 V-8 engine. This carburetor is a key component of the engine's intake system and plays a crucial role in maintaining its performance and power output.
The 2207SB carburetor comes equipped with two hollow square-shaped barrels, each containing a float bowl that holds the necessary fuel for the combustion process. The bowls are connected to a common base plate through float levers and needles, which regulate the fuel flow based on engine vacuum and throttle position. The carburetor features an automatic choke mechanism designed to ensure easy starting, especially in cold weather conditions.
The intake manifold on this 1955 Pontiac 287 V-8 is topped with an eddy current throttle position sensor that offers smooth and precise throttle response. This sensor works in conjunction with the Carter carburetor's throttle valves. Located at the base of each barrel, these valves are controlled by a linkage connected to the accelerator pedal and the throttle cable. They adjust the size of the air passage between the carburetor and the intake manifold, ultimately influencing the engine's power output.
The Carter 2207SB carburetor is regulated by four main jets: two idle jets located below the float bowls and two main jets positioned in the center of each barrel. These jets control the fuel mixture's richness or leanness, depending on engine RPM and throttle position. Furthermore, this carburetor includes an automatic enrichment system known as a power enricher circuit, which provides additional fuel for enhancing engine performance under heavy load or wide-open throttle conditions.
Additionally, the 1955 Pontiac 287 V-8's Carter 2207SB carburetor comes with various emissions-related components, such as an air cleaner, secondary air system, and heat risers. The air cleaner ensures an adequate supply of fresh, clean air for combustion, while the secondary air system and heat risers help control emissions by mixing fuel-air mixture with air from the engine's exhaust gases.
The Carter WG Series 2-barrel carburetor, model 2207SB, is a carefully engineered component that incorporates advanced design principles and materials to guarantee a consistent and efficient fuel-air mixture for the powerful 1955 Pontiac 287 V-8 engine. With its smooth operation and superior performance, this carburetor has become a highly coveted piece among classic car enthusiasts and collectors. The rich history and iconic design of the Pontiac 287 V-8, combined with the Carter 2207SB carburetor, guarantee an exhilarating driving experience.
