The Multiquip 16166ZH7W50 is a genuine OEM Main Nozzle designed for a wide range of Multiquip and portfolio-brand equipment including MVC-64H, MVC-64HW, MVH-R60H, MVH-R60W, and MVC64VHW plate compactors, MC-42S, EC-42S, MC44S, CMS-44S, CMS-4S, and WC-42S concrete mixers, CA4.4HM, CA-4-4H, CA4HM, and CA4HC walk-behind power trowels, and MQ-D206H, MQD2D3H, MQ-D305, D306, MQ-D306HA, MQD2H, SDP-2, SDP-3, and CA90749 diaphragm pumps, as well as QP2H, QP-204H, and CP-20H centrifugal pumps. As a genuine OEM component, part 16166ZH7W50 is manufactured to the exact specification of the original part it replaces, ensuring a direct fit without modification. Sourced through authorized channels, this Main Nozzle is the dependable choice when your Honda-powered Multiquip equipment needs a carburetor fuel circuit restored to proper working order. Verify your model against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Fuel Metering Accuracy — Manufactured to the exact fuel-jet sizing of the original carburetor component, preserving the correct air-fuel mixture for consistent engine operation.
- Direct Carburetor Drop-In — Designed to thread directly into the main jet circuit of the Honda GX-series carburetor used across multiple Multiquip equipment families, matching the original port dimensions and thread pitch.
- Broad Cross-Family Fitment — Covers MVC and MVH plate compactors, MC/EC/WC/CMS concrete mixers, CA-series walk-behind trowels, MQ and SDP diaphragm pumps, and QP/CP centrifugal pumps.
- Restored Engine Throttle Response — A correctly sized main nozzle maintains proper fuel flow at mid-to-high throttle; a worn or clogged nozzle causes lean running, power loss, and hard starting across all compatible equipment.
- Fuel System Integrity — Using the correct OEM-spec nozzle prevents lean-condition overheating and protects downstream engine components from damage caused by improper fuel delivery.
The main nozzle is a precision-drilled jet fitted inside the carburetor body that meters the volume of fuel drawn into the engine's air stream under normal running conditions. Its calibrated orifice controls the fuel-to-air ratio at mid and full throttle, directly affecting engine power output, fuel efficiency, and exhaust emissions. When the nozzle becomes clogged with varnish deposits or worn beyond its original bore diameter, the engine runs lean — symptoms include rough idling, loss of power under load, overheating, and difficulty maintaining speed on compactors, mixers, trowels, and pumps alike.
