Description
A015051 – C·T·S Metering Diaphragm Assembly (OEM Replacement Part)
The C·T·S A015051 Metering Diaphragm Assembly is a high-quality OEM replacement component designed to restore accurate fuel metering in compatible diaphragm-style carburetors used on outdoor power equipment. The metering diaphragm responds to engine vacuum, regulating fuel flow into the carburetor to provide consistent fuel delivery for smooth idling, responsive acceleration, and reliable engine performance.
Manufactured from premium fuel-resistant materials, the A015051 Metering Diaphragm Assembly is engineered to withstand modern gasoline blends, engine vibration, and demanding operating conditions. Replacing a worn, hardened, or damaged metering diaphragm helps eliminate common carburetor issues such as hard starting, rough idle, hesitation, flooding, and poor throttle response.
