Walbro 98-313-7 Throttle Return Spring

Product Description

The WALBRO 98-313-7 is a throttle return spring designed for use in small engine carburetor assemblies. This spring provides the return tension that pulls the throttle plate back to the idle or closed position after the operator releases the throttle input. Without proper spring tension, the throttle will not reliably return to idle, creating unsafe or erratic engine behavior. Licensed small engine technicians and equipment repair shops install this part during carburetor rebuilds, throttle linkage service, or as a direct replacement for a broken or fatigued original spring.

This throttle return spring is suited for small engine applications where Walbro carburetors are commonly found, including outdoor power equipment such as chainsaws, string trimmers, leaf blowers, and similar handheld or walk-behind power tools. It is a direct OEM replacement intended to restore proper throttle response and idle control in equipment equipped with compatible Walbro carburetor configurations.

Installation Notes

Installation is typically performed by a small engine technician or qualified equipment repair professional. Before servicing the carburetor or throttle linkage, shut off the engine and allow it to cool completely, and disconnect the spark plug wire to prevent accidental starting. Use appropriate hand tools and refer to the equipment manufacturer's service manual for throttle linkage routing and spring attachment points. Inspect surrounding linkage components for wear while the carburetor is accessible.
