The Honda 16561-ZA0-L00 Governor Spring is a genuine OEM Governor Spring designed for the H4514 lawn tractor. Sourced directly from Honda, this part meets the exact specifications of the original component it replaces. If your tractor is surging, hunting, or failing to hold a steady engine speed, a worn or fatigued governor spring is a common culprit — and this OEM replacement restores correct governor response.
Key Features
- Genuine OEM Tension Calibration — manufactured to Honda's original spring rate, ensuring the governor mechanism responds accurately across the throttle range rather than over- or under-correcting engine speed
- Direct OEM Replacement — matches the original hook geometry and free length of the production part for a straight swap with no rework needed on the governor linkage
- Built for the H4514 Lawn Tractor — confirm your serial number against the fitment table before ordering, as Honda supersedes governor components at specific serial breaks
The governor spring is a critical link in the mechanical governor system that keeps engine speed steady under changing load. It works in tension against the governor arm, pulling the throttle toward open as engine speed drops under load and allowing it to return as speed recovers — the balance between the spring and the flyweights is what holds a consistent rpm. A spring that has lost its tension or taken a permanent set allows the governor to overreact or underreact, producing the surging and speed fluctuation that makes a tractor difficult to operate under load. Replacing a fatigued spring with a correctly rated OEM unit restores stable, predictable speed control.
