The Multiquip 16166ZF6V00 Main Nozzle is a genuine OEM component designed for MRH800GS walk-behind rollers, WM120SH and WM120PH Whiteman mortar mixers, and EM120S and EM120P Series Essick mixers. As a direct OEM replacement, it meets the original engineering standards set for each of these machine families, ensuring the carburetor delivers the correct fuel-air mixture your engine depends on. Sourced directly through authorized Multiquip distribution channels, this is the same nozzle that ships with new equipment — not an approximation of it. Confirm your model code against the fitment list above before ordering to ensure a correct match.
Key Features
- Genuine OEM Fuel Metering Accuracy — Manufactured to exact bore dimensions, ensuring the carburetor delivers a precisely calibrated fuel-air ratio rather than an approximated flow rate.
- Drop-In Carburetor Fitment — Designed to seat directly into the carburetor body without modification, using the same thread spec and nozzle geometry as the original component.
- Broad Model Coverage — Compatible with MRH800GS, WM120SH, WM120PH, EM120S Series, and EM120P Series equipment across multiple Multiquip product families.
- Consistent Engine Performance — A correctly functioning main nozzle keeps fuel delivery smooth across the RPM range; a clogged or worn nozzle causes rough running, hard starts, and poor throttle response.
- Fuel System Integrity — Using the correct OEM nozzle helps prevent lean-running conditions that can cause overheating and accelerated engine wear over time.
The main nozzle is a small but critical component inside the carburetor responsible for metering fuel flow into the engine's air stream during normal operation. It controls how much fuel is drawn through the carburetor at mid to full throttle, directly affecting engine power output, fuel efficiency, and combustion consistency. When the main nozzle becomes clogged, corroded, or worn, the engine will run lean, surge under load, or fail to reach full power — making timely replacement essential to keeping the engine running as intended.
