The Carter BBD float circuit is an essential component of the carburetor system. It plays a crucial role in regulating the flow of fuel into the carburetor bowl, ensuring a consistent fuel level for optimal engine performance. The float, needle valve, and seat assembly work together to control the fuel supply, allowing the engine to operate smoothly and efficiently. This circuit is designed to maintain the correct fuel level, preventing fuel starvation or flooding that could negatively impact the engine's performance. It is an integral part of the carburetor system, contributing to the overall functionality and reliability of the vehicle's engine.
This adjustment must be made with the bowl cover gasket removed. Hold the lip on float arm against the seated intake needle, making sure the float pin is at the bottom of its guide slots. The distance (A) from the top surface of the body casting to the top of each float (at free end) should be as listed on carburetor spec page. If one float is lower that the other, equialize by bending the float arm. If both floats require the same correction, adjust by bending lip on float arm. The floats must not rub anywhere against the inner walls of the bowl. If necessary, bend float arms slightly to provide clearance on all sides of floats.
CAUTION: Do not bend lip while float is resting against inlet needle to avoid damaging viton needle tip
