The Honda 16166-ZM1-003 Main Nozzle is a genuine OEM component designed for GCV135 vertical shaft engines. As a direct Honda replacement, this nozzle meets the original engineering specifications for fuel metering — the precision that keeps the carburetor running correctly depends on it. Verify your engine's serial number against the fitment table before ordering to confirm this is the right nozzle for your unit.
Key Features
- Exact Fuel Metering — genuine OEM construction ensures the orifice diameter matches Honda's original specification for the GCV135 carburetor, maintaining correct air-fuel ratio across the engine's operating range
- Direct OEM Replacement — sourced from Honda, this nozzle installs into the GCV135 carburetor without modification, restoring the fuel circuit to its original condition
- Serial Number Verification Recommended — Honda updates carburetor components at production serial breaks; confirm your engine's serial number against the fitment table to ensure part number 16166-ZM1-003 is correct for your unit
The main nozzle is the primary fuel-metering jet inside the carburetor. It controls the volume of fuel drawn into the air stream during mid-range and full-throttle operation, and its calibrated orifice is what keeps combustion efficient and power output consistent. When the main nozzle becomes clogged, worn, or damaged, the engine typically runs lean — resulting in hesitation, loss of power, or overheating — and cleaning alone may not restore correct fuel delivery if the orifice geometry has changed. Replacing it with a genuine Honda nozzle restores accurate fuel metering and brings the carburetor back to proper working condition.
