The Honda 16512-ZM0-000 Governor Weight Holder is a genuine OEM Governor Weight Holder designed for GCV135, GCV160, GCV170, GCV190, GCV200, and GSV190 vertical shaft engines, as well as HRB216, HRB217, HRC216, HRN216, HRR216, HRS216, HRT216, HRX217, and HRZ216 lawn mowers. As a direct Honda OEM component, this part is manufactured to the same specification as the original, ensuring a correct fit without modification. Honda supersedes parts at production breaks, so always verify your engine or mower serial number against the fitment table before ordering.
Key Features
- Genuine OEM Governor Precision — sourced directly from Honda, this holder maintains the exact centrifugal weight geometry the governor system depends on for accurate throttle control
- Direct OEM Replacement — matches the original part's dimensions and mounting interface, dropping into place without rework on any listed engine or mower
- Broad Vertical-Engine Fitment — covers GCV135, GCV160, GCV170, GCV190, GCV200, and GSV190 engines, plus HRB216, HRB217, HRC216, HRN216, HRR216, HRS216, HRT216, HRX217, and HRZ216 lawn mowers — confirm your serial number to be sure
- Restores Stable Engine Speed — a worn or damaged holder allows governor weights to shift improperly, causing surging, hunting, or runaway RPM; replacing it brings engine speed back under control
The governor weight holder is the structural carrier for the centrifugal flyweights in Honda's mechanical governor system. As engine speed rises, the flyweights pivot outward against spring tension; the holder keeps them correctly positioned so that movement is translated accurately into throttle adjustment. When the holder cracks, wears, or loses its geometry, the flyweights no longer respond consistently — the result is unstable engine speed, surging at idle, or an engine that cannot hold a steady RPM under load. Replacing this component restores the precision the governor needs to keep the engine running smoothly across varying load conditions.
