B1A015050 DIAPHRAGM ASS’Y METERING

One New Aftermarket Replacement Metering Diaphragm Assembly Fits Zama C1M and C1Q Series Carburetors

This carburetor metering diaphragm assembly is a critical internal component of Fits Zama C1M and C1Q series carburetors, regulating fuel flow through the metering chamber to ensure consistent fuel delivery, proper idle, and reliable throttle response. A worn, cracked, or perforated metering diaphragm is a common cause of hard starting, erratic idle, and lean-running conditions in small two-stroke engines. Replacing it restores proper carburetor function without the need for a full carburetor replacement.

Fits Zama carburetors are widely used across chainsaws, string trimmers, leaf blowers, hedge trimmers, and other handheld outdoor power equipment. Verify your carburetor model number before ordering to confirm fitment.
