The Honda 16561-Z9W-000 Governor Spring is a genuine OEM component designed for GCV170 and GCV200 vertical shaft engines. As a direct OEM replacement, this spring is manufactured to Honda's exact tension specifications, ensuring the governor system responds correctly to load changes and holds the engine at its set speed. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and this spring may not apply to every production run of these models.
Key Features
- Genuine OEM Tension Accuracy — sourced directly from Honda, this spring delivers the exact load rate the governor linkage depends on for consistent speed regulation under varying throttle demand.
- Direct OEM Replacement — engineered to the same specification as the original, this part drops into the governor assembly without modification, restoring proper linkage action on GCV170 and GCV200 engines.
- GCV170 and GCV200 Fitment — built specifically for Honda's residential vertical shaft engine series; verify your serial number against the fitment table to confirm the correct part for your unit.
- Speed Stability Under Load — a worn or fatigued governor spring causes the engine to hunt, surge, or run at the wrong speed; replacing it restores steady, controlled operation across the RPM range.
The governor spring is a tensioning element within the mechanical governor system, working alongside the governor arm and linkage to regulate engine speed. It applies a calibrated return force that balances against centrifugal flyweight action, keeping the throttle plate at the correct position as engine load rises and falls. When the spring loses tension or breaks, the governor loses its ability to counteract the flyweights accurately, resulting in speed surging, hunting at idle, or an inability to hold a steady RPM under load.
