Sourced directly through authorized Multiquip supply channels, part number 16166ZE3F10 is the correct replacement when restoring carburetor function on these machines. DHS Equipment stocks genuine Multiquip parts to help you get the right component the first time.
Key Features
- Genuine OEM Fuel Metering Accuracy — Manufactured to the original carburetor specification for the GX340 engine, ensuring the correct fuel-to-air ratio is maintained at idle and under load.
- Drop-In Carburetor Fit — Replaces the original main nozzle in the carburetor bore without machining or adjustment, restoring the assembly to as-built condition.
- Confirmed Fitment — Compatible with GA6HB, GA6HEB, GAW180HE, GAW180HE1, and GAW180HEA gasoline generators and arc welders in the Multiquip lineup.
- Consistent Engine Output — A worn or corroded main nozzle causes rough idle, rich or lean running, and loss of power; replacing it with part 16166ZE3F10 restores clean, stable engine operation.
- Fuel System Integrity — Correct nozzle sizing prevents fuel flooding and uncontrolled enrichment, which are leading causes of hard starting and excessive emissions on small gasoline engines.
The main nozzle is a precision-drilled jet located inside the carburetor body that meters the volume of fuel drawn into the airstream during engine operation. Its orifice size is calibrated to the engine's displacement and carburetor design, and any wear, corrosion, or deposits that alter that opening will directly affect how the engine runs — causing symptoms such as rough idle, black smoke, or an inability to reach full power. Replacing a degraded main nozzle with the correct OEM part restores the fuel delivery calibration the engine was built around.
