Walbro 98-3228-7 Spring Metering

Product Description

The WALBRO 98-3228-7 is a metering spring used in small engine carburetor assemblies. Metering springs regulate fuel delivery by controlling diaphragm tension inside the carburetor, which directly affects the air-fuel mixture at varying throttle positions. This component is a service replacement part intended for use by small engine technicians and equipment repair professionals working on outdoor power equipment and lawn and garden machinery.

This metering spring is suited for carburetor repair and rebuild applications on small displacement engines commonly found in handheld and walk-behind outdoor power equipment. It is typically replaced during carburetor overhaul when the existing spring shows fatigue, deformation, or loss of tension that contributes to poor fuel metering, rough idle, or hard starting conditions.

Key Features

• Designed as an OEM-specification metering spring for carburetor diaphragm assemblies
• Controls diaphragm tension to maintain consistent fuel delivery across throttle range
• Direct replacement intended to restore proper carburetor function
• Manufactured by WALBRO, a recognized supplier of small engine fuel system components

Compatibility

Designed as an OEM-style replacement metering spring for WALBRO carburetor assemblies used in lawn and garden equipment applications.

Installation Notes

Installation is performed by small engine technicians during carburetor disassembly and rebuild. Shut off all fuel supply and allow the engine to cool completely before beginning carburetor service. Handle the metering spring carefully to avoid deformation, as altered spring tension will affect fuel delivery calibration. Follow the equipment manufacturer's service manual for correct reassembly sequence and diaphragm orientation.
