The Honda 16512-ZM7-000 Governor Weight Holder is a genuine OEM Governor Weight Holder designed for the GXV57 vertical shaft engine. Sourced directly from Honda, this component meets the exact tolerances the original design calls for, making it a direct-fit replacement for the factory part. If your engine is hunting, surging, or failing to hold a steady speed, this is one of the first components to inspect and replace.
Key Features
- Genuine OEM Precision — manufactured to Honda's original specifications, ensuring the governor weights seat and rotate correctly for accurate centrifugal speed sensing
- Direct Replacement — engineered to drop into the GXV57 vertical shaft engine in place of the original, with no rework or adaptation needed to the surrounding governor assembly
- Steady-Speed Performance — a correctly functioning holder keeps the flyweight arms in proper geometry; a worn or cracked holder allows inconsistent weight movement, leading to engine hunting and speed instability under load
- Verify Your Serial Number — Honda supersedes parts at production serial breaks, so confirm part number 16512-ZM7-000 against your engine's serial number in the fitment table before ordering
The governor weight holder is a core component of the mechanical centrifugal governor fitted to the GXV57 vertical shaft engine. It carries the flyweights that spin with the crankshaft and translate engine speed into a mechanical signal — as RPM rises, centrifugal force pushes the weights outward against the holder, repositioning the governor arm to reduce throttle and maintain a set speed. When the holder cracks, wears, or loses its geometry, the weights can no longer move freely or consistently, causing the engine to hunt, surge, or run at an uncontrolled speed. Replacing this part restores the governor's ability to hold steady RPM under varying load conditions.
