Zama A015077 Metering Diaphragm Assembly for C1Q-S and C1U Carburetors

The Zama A015077 Metering Diaphragm Assembly is a genuine OEM replacement component designed for Zama C1Q-S and C1U series carburetors commonly found in two-stroke small engines. This critical fuel system component regulates fuel flow to ensure proper engine performance and reliable operation.

Key Features:

• Genuine Zama OEM replacement part ensuring exact fit and optimal performance
• Made from flexible convoluted material designed for greater movement and durability
• Controls fuel flow in the metering chamber similar to a float system but unaffected by engine orientation
• Works in conjunction with the metering lever and inlet needle to maintain proper fuel pressure
• Replaces multiple OEM part numbers including A015011, A015016, A015019, A015041, A015042, A015044, A015050, and A015077

The metering diaphragm is an essential component of the carburetor's fuel metering system. As the engine runs and draws fuel from the metering chamber, the diaphragm moves upward to contact the metering lever, which opens the inlet needle and allows fresh fuel to flow into the chamber. This precise control mechanism ensures consistent fuel delivery regardless of the engine's position, making it ideal for handheld equipment like chainsaws, trimmers, and blowers. Regular replacement of worn or damaged diaphragms restores proper fuel flow and eliminates common performance issues such as poor acceleration, rough idle, or difficulty starting.
