The Honda 16561-Z9P-000 Governor Spring is a genuine OEM component designed for GCV170 and GCV200 vertical shaft engines and the HRX217 lawn mower. As an authentic Honda part, it is manufactured to the same specification as the spring installed at the factory, ensuring the governor system responds exactly as intended. This part fits across several serial ranges, so confirm your machine's serial number against the fitment table before ordering.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this spring meets the tension and travel specifications the governor system depends on for accurate throttle regulation.
- Correct Tension for Stable Speed Control — governor spring tension determines how quickly and precisely the engine responds to load changes; a stretched or broken spring causes hunting, surging, or runaway speed.
- Broad Fitment — designed for GCV170 and GCV200 vertical shaft engines, including those powering the HRX217 lawn mower.
- Check Your Serial Number — Honda supersedes parts at serial breaks, so verify your machine's serial number against the fitment table to confirm part number 16561-Z9P-000 is correct for your unit.
The governor spring is a small but essential part of the mechanical governor assembly. It works in tension against the governor flyweights to set the target engine speed, keeping the throttle in balance under varying load conditions. When the spring loses tension, stretches, or breaks, the governor loses its reference point — the engine may surge rhythmically, hunt for a steady speed, or in some cases accelerate beyond the set RPM, making a replacement spring critical to smooth, controlled operation.
