Walbro 95-561-8 Metering Diaphragm Assembly

Product Description

The WALBRO 95-561-8 is a metering diaphragm assembly designed for use in small engine carburetors. The metering diaphragm is a critical internal carburetor component that regulates fuel delivery by responding to engine vacuum and maintaining proper fuel-to-air mixture. Over time, diaphragms harden, crack, or lose flexibility, causing hard starting, rough idle, and lean-running conditions. Replacing the metering diaphragm with an OEM-specification part restores proper carburetor function. This assembly is a Walbro-branded service part intended for technicians performing carburetor rebuilds on outdoor power equipment.

This metering diaphragm assembly is used in small engine applications commonly found in lawn and garden equipment, including handheld and walk-behind power tools. Typical applications include chainsaws, string trimmers, leaf blowers, hedge trimmers, and related outdoor power equipment fitted with Walbro carburetors. It is installed during carburetor overhaul or as part of a rebuild kit procedure when the original diaphragm shows signs of wear, distortion, or fuel degradation damage.

Installation Notes

Installation is performed by small engine technicians during carburetor disassembly and rebuild. Shut off the fuel supply and relieve any residual pressure before opening the carburetor. Handle the diaphragm carefully during installation to avoid stretching or tearing, and ensure the seating surface is clean and free of debris before reassembly. Follow the equipment manufacturer's service manual for torque and reassembly sequence.
