Multiquip EM16166 Main Nozzle

The Multiquip EM16166 is a genuine OEM Main Nozzle designed for a wide range of Multiquip and Whiteman equipment, including plate compactors, rammers, walk-behind trowels, mixers, masonry saws, rollers, pumps, generators, and welders. As a factory-sourced component, EM16166 meets the original engineering specifications for every machine it serves — from MVC and MVH series plate compactors and MTX series rammers to WM and MC series mixers, MP series masonry saws, AR series rollers, QP series pumps, and GA series generators. Stocking this part ensures you can keep a broad fleet of equipment running without hunting down multiple supplier sources. DHS Equipment supplies this part direct as an authorized Multiquip OEM replacement.

Key Features

• Genuine OEM Fuel Delivery Accuracy — Manufactured to Multiquip's original flow specifications so the carburetor circuit receives precisely metered fuel, not an approximation.
• Drop-In Carburetor Compatibility — Engineered to seat and seal exactly as the original, requiring no reworking of surrounding carburetor components during installation.
• Broad Fleet Coverage — A single part number covers MTX rammers, MVC and MVH plate compactors, MP masonry saws, MC and WM mixers, AR and V series rollers, QP pumps, GA generators, and more — simplifying parts inventory across a mixed fleet.
• Consistent Engine Starting and Throttle Response — A correctly functioning main nozzle maintains the air-fuel ratio needed for clean starts and stable power output; a worn or clogged nozzle causes hard starts, rough running, and loss of working power.
• Fuel System Integrity — Correct nozzle fit prevents unmetered fuel bypass within the carburetor body, supporting safe and efficient combustion across all covered equipment.

The main nozzle is a precision metering component located inside the carburetor. Its role is to control the volume of fuel drawn into the air stream during normal engine operation, maintaining the correct air-to-fuel ratio for efficient combustion. When the main nozzle becomes worn, corroded, or blocked — whether from stale fuel deposits or particulate contamination — the engine loses the ability to sustain a steady fuel mixture, resulting in rough idling, power loss, black smoke, or a complete failure to run at working speed. Replacing a degraded nozzle with a genuine OEM part restores the precise metering the carburetor was designed around.
