The Honda 16166-Z8C-801 Main Nozzle is a genuine OEM component designed for the GC190 horizontal shaft engine. Sourced directly from Honda, this nozzle meets the exact specifications required for correct fuel metering in the carburetor. Confirm your engine's serial number against the fitment table before ordering to ensure this is the right part for your unit.
Key Features
- Exact Fuel Metering — as a genuine OEM part, this nozzle is manufactured to Honda's precise calibration for the GC190 carburetor, delivering the correct air-fuel ratio the engine depends on for clean, consistent running.
- Direct Carburetor Fit — this is the Honda-specified replacement for the GC190 engine; no modification is needed to install it in place of a worn or clogged original.
- Serial Number Verification Recommended — Honda supersedes parts at production breaks, so check your engine's serial number against the fitment table to confirm part number 16166-Z8C-801 is correct for your GC190.
- Restores Engine Performance — a blocked or damaged main nozzle starves the engine of fuel at mid and full throttle, causing hesitation, power loss, and hard starting; replacing it with this OEM nozzle restores proper fuel delivery.
The main nozzle is a precision-drilled metering component inside the carburetor. It controls the volume of fuel drawn into the airstream at mid-range and wide-open throttle, and its calibrated orifice size is what sets the correct mixture for the engine's displacement and tuning. When the nozzle becomes clogged with varnish deposits or wears out of spec, the engine runs lean, loses power, surges, or refuses to rev cleanly. Replacing the nozzle with a genuine Honda part restores the fuel delivery the carburetor was designed around.
