The Honda 16562-Z6L-010 Throttle Return Spring is a genuine OEM component designed for GX630, GX660, and GX690 horizontal shaft engines and the EB10000 generator. As a direct Honda OEM replacement, this spring carries the same specifications as the part it replaces, ensuring the throttle linkage responds exactly as Honda engineered it to. Confirm your machine's serial number against the fitment table before ordering, as Honda supersedes parts at specific serial breaks.
Key Features
- Genuine OEM Tension Spec — manufactured to Honda's exact load rating, so the throttle plate snaps back to its rest position with consistent, calibrated force every time the throttle is released.
- Direct OEM Replacement — this is the same spring supplied through Honda's own service network, connecting directly into the existing throttle linkage with no adaptation required.
- Broad Fitment — covers GX630, GX660, and GX690 horizontal shaft engines as well as the EB10000 generator; verify your serial number against the compatibility table to confirm the correct part for your unit.
- Throttle Response Integrity — a fatigued or broken throttle return spring causes sluggish or uncontrolled throttle response, which affects governed speed stability and can make the engine difficult to manage under load.
The throttle return spring holds tension on the throttle linkage, pulling the throttle plate back to its idle or closed position whenever operator input is released. On governed engines and generator sets, this spring works in conjunction with the governor to maintain steady engine speed — without it, the throttle may hang open, fail to return smoothly, or respond erratically to load changes. A worn or broken spring disrupts the entire governor-throttle relationship, so replacing it promptly restores predictable speed control and protects the engine from over-revving.
