Multiquip 16562 Throttle Return Spring

The Multiquip 16562 Throttle Return Spring is a genuine OEM component designed for a wide range of Multiquip, Whiteman, and Essick equipment including rollers, rammers, plate compactors, pumps, concrete mixers, masonry saws, generators, and power trowels. As a direct OEM replacement, this spring is manufactured to the same specifications as the original part, ensuring consistent throttle response and proper engine control across every compatible machine. Verified fitment includes models such as AR13H, MTX70HDR, MTX80HDR, MVC82VHW, MVH408GH, WM120SH, QP3TH, SP118, and many more — confirm your model code before ordering to ensure compatibility.

Key Features

• Genuine OEM Spring Tension — Manufactured to the original spring rate specification, ensuring the throttle snaps back to idle consistently without sluggish or incomplete return.
• Direct Drop-In Replacement — Installs in the same throttle linkage position as the original, with no modification to the carburetor or throttle lever assembly required.
• Broad Cross-Equipment Fitment — Compatible across rollers, rammers, plate compactors, pumps, mixers, saws, generators, and trowels including AR13H, MVC82VHW, MTX70HDR, MVH408GH, WM120SH, QP3TH, and SP118 series.
• Throttle Control Integrity — A correctly tensioned return spring keeps the engine from over-revving when the operator releases the throttle, protecting both the engine and the equipment being operated.
• Engine Safety Function — A failed or stretched throttle return spring can prevent the engine from returning to idle, creating a runaway throttle condition — replacing it promptly restores safe engine speed control.

The throttle return spring is a small but critical component in the engine's throttle linkage system. Its job is to pull the throttle lever back to the idle position the moment the operator releases pressure — without it, the carburetor butterfly valve may stay partially or fully open, causing the engine to continue running at elevated RPM. Over time, these springs can fatigue, stretch, or corrode, leading to sluggish throttle response or a throttle that fails to return to idle entirely. Replacing a worn spring restores precise throttle control and protects the engine from unnecessary wear caused by unintended high-speed operation.
