The Honda 16562-Z6M-000 Throttle Return Spring is a genuine OEM component designed for GX630, GX660, and GX690 horizontal shaft engines and GXV630, GXV660, and GXV690 vertical shaft engines. As a direct Honda OEM replacement, this spring is manufactured to the exact specifications required for correct throttle actuation and reliable return action. Confirm your engine model and serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks across these engine families.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this spring is manufactured to the precise tension and geometry the throttle linkage on these engines requires for consistent, predictable throttle response.
- Correct Return Force — a throttle return spring that has lost tension or broken will cause the throttle to stick or fail to return to idle, creating erratic engine speed; this replacement restores proper return action immediately.
- Broad Engine Family Coverage — fits GX630, GX660, and GX690 horizontal shaft engines as well as GXV630, GXV660, and GXV690 vertical shaft engines, covering a wide range of high-displacement Honda power units.
- Check Your Serial Number — Honda updates parts at serial number breaks within these engine families; verify your serial number against the fitment table to confirm this is the correct spring for your unit.
The throttle return spring is a small but critical component in the engine's throttle control system. Its job is to pull the throttle plate or throttle lever back to the idle or closed position as soon as the operator releases the throttle input, ensuring the engine returns to a safe idle speed rather than holding an elevated RPM. When this spring weakens, takes a set, or breaks, the throttle may stick open or respond sluggishly, making the engine difficult to control and potentially causing over-speed conditions in the equipment it powers.
