The Honda 16166-Z1A-003 Main Nozzle is a genuine OEM component designed for GC190 horizontal shaft engines. Sourced directly from Honda, this part carries the same specifications as the original, ensuring the carburetor meters fuel exactly as intended. Confirm part number 16166-Z1A-003 against your engine's serial number and parts diagram before ordering to ensure this is the correct nozzle for your serial range.
Key Features
- Genuine OEM Fuel Metering Accuracy — manufactured to Honda's original calibration, this nozzle delivers the precise fuel-to-air ratio the GC190 carburetor is designed around, preventing the rich or lean running conditions that an off-spec nozzle can cause.
- Direct Carburetor Replacement — this nozzle installs into the GC190 carburetor as an exact match, eliminating the guesswork of sourcing a compatible substitute.
- Fits GC190 Horizontal Shaft Engines — designed specifically for the GC190 engine; verify your unit's serial number against the fitment table to confirm applicability within your serial range.
The main nozzle is a precision-calibrated metering jet inside the carburetor. It controls the volume of fuel drawn into the airstream during normal throttle operation, directly governing how cleanly and efficiently the engine runs. When a main nozzle becomes clogged, worn, or damaged, the engine will typically run rough, stumble under load, or stall — replacing it with a correctly sized OEM nozzle restores proper fuel delivery and stable power output.
