Multiquip 16511 Governor Weight

The Multiquip 16511 Governor Weight is a genuine OEM component designed for a wide range of Honda-engine-powered Multiquip equipment, including generators, rollers, plate compactors, concrete mixers, masonry saws, pumps, welders, and walk-behind trowels. As a direct OEM replacement, this part meets the same specifications as the original installed at the factory, ensuring consistent engine governing behavior across every application it supports. Confirmed fitment spans models including GA9.7HE, AR13H, AR13HA, AR13HC, MRH800GS, MVH408GH, MVC82VHW, MVC88VTHW, MC12PH, WM120SH, WM70S/P, QP3TH, QP402H, SP118, MP2090HP, GAW180HE, V305EH, R2000H, WRSPUDF, WRS5200, and many additional series.

Key Features

• Genuine OEM Centrifugal Mass: Manufactured to the original weight specification that determines flyweight throw — critical for accurate RPM regulation on Honda engines across this broad equipment range.
• Drop-In Governor Assembly Fit: Installs directly onto the Honda engine governor shaft assembly with no modification, maintaining correct flyweight spacing and pivot geometry.
• Broad Cross-Equipment Fitment: A single OEM part number covering generators (GA9.7HE, GA6HEB, GA3.6HR), rollers (AR13H, AR14H, V305EH, R2000H), plate compactors (MVH408GH, MVC82VHW, MVC88VTHW, MVH128GH), mixers (MC12PH, WM120SH, MC94P/S), saws (SP118, MP2090HP, MP1455HP), pumps (QP3TH, QP402H), and more.
• Stable Engine Speed Under Load: A correctly weighted governor flyweight keeps engine RPM at the set point as load changes — a worn or damaged weight causes surging, hunting, or uncontrolled RPM that reduces output quality and accelerates engine wear.
• Fuel System Protection: Proper governor action prevents over-revving under no-load conditions, protecting the carburetor, fuel system, and connected drivetrain components from damage caused by unregulated engine speed.

The governor weight is a flyweight component mounted on the engine's governor shaft. As engine speed rises, centrifugal force causes the weights to swing outward, mechanically signaling the throttle linkage to reduce fuel delivery and hold RPM at the target setting. When the engine is loaded and speed drops, the weights retract, opening the throttle to restore power. When a governor weight is worn, cracked, or out of specification, the governor loses the ability to sense and respond to speed changes accurately, causing the engine to surge, hunt between RPM points, or run dangerously fast at no load — all of which affect both the output quality of the connected equipment and the longevity of the engine itself.
