Zama A015055 Metering Diaphragm Assembly Carburetor

The Zama A015055 Metering Diaphragm Assembly is a genuine OEM replacement component designed for select Zama carburetor models. This critical carburetor part regulates fuel flow from the metering chamber by responding to engine vacuum and fuel demand, ensuring proper fuel delivery for optimal engine performance.

Key Features:

• Genuine Zama OEM replacement part
• Precision-engineered flexible diaphragm material for reliable fuel metering
• Essential component for maintaining proper air-fuel mixture
• Designed for use in 2-stroke small engine carburetors
• Includes diaphragm and mounting gasket assembly

The metering diaphragm assembly works in conjunction with the metering lever and inlet needle to maintain consistent fuel pressure in the carburetor's metering chamber. When the diaphragm becomes worn, cracked, or loses flexibility, symptoms may include hard starting, rough idle, poor acceleration, or engine stalling. Regular replacement of this component during carburetor rebuilds helps ensure reliable engine operation.

Commonly used in outdoor power equipment including chainsaws, string trimmers, leaf blowers, hedge trimmers, and other handheld equipment powered by 2-stroke engines with Zama carburetors.
