The Honda 16166-ZH8-E80 Main Nozzle is a genuine OEM carburetor component designed for GX160 horizontal shaft engines and Honda EB, EM, and EP-series generators including the EB2200, EB2500, EM1600, EM1800, EM2200, EM2500, and EP2500. As a direct-sourced Honda OEM part, it delivers the exact fuel metering calibration the carburetor was designed around, ensuring the engine runs at the correct air-fuel mixture straight out of the box. Confirm your unit's serial number against the fitment table before ordering, as Honda updates parts at specific serial breaks within a model run.
Key Features
- Exact Fuel Metering — genuine OEM construction means the orifice diameter matches Honda's carburetor specification precisely, so fuel delivery stays within the narrow tolerance that correct combustion depends on
- Direct OEM Replacement — this nozzle slots into the carburetor body exactly as the original, with no fitting adjustments needed
- Broad Honda Fitment — covers the GX160 horizontal shaft engine alongside the EB2200 inverter generator and EB2500, EM1600, EM1800, EM2200, EM2500, and EP2500 generators; verify your serial number against the fitment table to confirm the correct part for your unit
- Restore Lost Power and Smooth Running — a clogged or worn main nozzle starves the engine of fuel at mid-to-high throttle, causing surging, black smoke, or hard starting; replacing it restores clean, stable power output
The main nozzle is the primary fuel-metering jet inside the carburetor. It controls the volume of fuel drawn into the airstream at normal operating speeds, and its calibrated orifice is what sets the correct air-fuel ratio for steady, efficient combustion. Because the orifice is extremely small, it is highly susceptible to blockage from varnish deposits left by stale fuel — a partially blocked nozzle causes the engine to run lean, surge under load, or lose power at higher throttle positions. Replacing a fouled or damaged main nozzle with a correct OEM unit is one of the most effective steps in a carburetor service.
