The Honda 16555-Z0L-801 Governor Rod is a genuine OEM component designed for GCV160 and GCV190 vertical shaft engines, the GSV190 vertical shaft engine, and HRB217, HRC216, HRR216, HRS216, HRT216, and HRX217 lawn mowers. As a direct Honda OEM part, it is manufactured to the same specification as the rod installed at the factory, ensuring the governor linkage operates exactly as intended. Honda supersedes parts across serial breaks, so confirm your machine's serial number against the fitment table before ordering to make sure part number 16555-Z0L-801 is the correct rod for your unit.
Key Features
- Genuine OEM Linkage Geometry — machined and formed to Honda's exact dimensions, so the governor arm, throttle plate, and rod work together with the correct travel and spring tension rather than binding or running loose
- Direct Drop-In Replacement — connects to the existing governor arm and throttle linkage without modification, restoring the governor circuit to its original operating condition
- Broad Fitment — covers GCV160, GCV190, and GSV190 vertical shaft engines as well as HRB217, HRC216, HRR216, HRS216, HRT216, and HRX217 lawn mowers; verify your serial number against the fitment table to confirm applicability
- Speed Stability Under Load — a correctly functioning governor rod keeps engine speed steady as cutting conditions change; a bent, worn, or disconnected rod allows the engine to hunt, surge, or overrev under varying loads
The governor rod is the rigid link that translates movement from the mechanical governor assembly into throttle position. When the engine speeds up under a lightening load, the governor flyweights push outward, rotating the governor shaft and moving the rod, which pulls the throttle toward closed to bring speed back down — and vice versa when load increases. This feedback loop keeps engine speed consistent regardless of what the equipment is doing. A rod that is bent, cracked, or has worn connection points breaks that loop, causing the engine to surge rhythmically, hunt for a stable speed, or climb past its governed limit — all of which reduce power delivery and accelerate wear on the engine.
