The Honda 16511-883-300 Governor Weight is a genuine OEM replacement built for an exceptionally wide range of Honda equipment, including G150, G200, G300, and G400 horizontal shaft engines, GV200 and GV400 vertical shaft engines, E1500, E2500, E3500, E4500, ED1000, EG1000, EG1500, ES3500, ES4500, and EV4000 generators, F400, F500, FR500, and FR700 tillers, the HR21 lawn mower, HS35 single-stage and HS50 and HS70 two-stage snow blowers, HT3810 lawn tractor, and WA20, WA30, WB20, WB30, WT20, and WT30 water pumps. As a genuine Honda OEM component, this Governor Weight is manufactured to the same specification as the original part it replaces, ensuring proper governor system operation across every compatible application. Because Honda has superseded parts at various serial number breaks across this broad equipment range, always verify your machine's serial number against the fitment table before ordering.
Key Features
- Genuine OEM Governor Calibration — sourced directly from Honda, this weight is calibrated to deliver the correct centrifugal force for accurate engine speed regulation, which a worn or out-of-spec weight cannot provide.
- Broad Cross-Equipment Compatibility — a single part number covering G-series and GV-series engines, Honda generators, tillers, lawn mowers, snow blowers, a lawn tractor, and water pumps; confirm your model and serial number in the fitment table before purchasing.
- Direct OEM Replacement — replaces the original Governor Weight without modification, restoring the mechanical governor assembly to its intended operating condition.
- Serial Number Verification Recommended — Honda has updated parts across serial breaks on many of these models; check your unit's serial number against the compatibility table to confirm this is the correct weight for your specific machine.
The governor weight is a rotating flyweight inside the mechanical centrifugal governor assembly. As engine speed rises, centrifugal force causes the weights to swing outward; this movement is translated through the governor linkage to reduce throttle and bring rpm back down. When speed drops, the weights retract and the throttle opens again. This constant mechanical feedback loop keeps the engine running at a consistent speed under varying load conditions. A worn, cracked, or out-of-balance governor weight disrupts this cycle, resulting in hunting, surging, or an engine that runs uncontrollably fast or refuses to hold a steady speed under load.
