The Honda 16016-ZE0-005 Pilot Screw Set is a genuine OEM component designed for a wide range of Honda engines, generators, tillers, lawn mowers, riding mowers, lawn tractors, multi-purpose tractors, power carriers, snow blowers, water pumps, outboard motors, and welder generators. As a direct Honda OEM part, this Pilot Screw Set is manufactured to the same specification as the original, ensuring the correct metering geometry for proper fuel-air mixture control. This part covers an exceptionally broad fitment range — including GX160 and GX390 horizontal shaft engines, GXV160 vertical shaft engines, EB and EG generator lines, WT30 and WB20 water pumps, BF2 and BF20 portable outboard motors, and many more — so buyers should confirm their model and serial number against the fitment table before ordering.
Key Features
- OEM Fuel Metering Accuracy — as a genuine Honda part, this Pilot Screw Set delivers the exact taper angle and thread specification needed to set idle mixture correctly, preventing rough idle and lean-run conditions.
- Direct OEM Replacement — this set threads in as the original did, with no re-tapping or adjustment to the carburettor body required beyond standard pilot circuit tuning.
- Broad Honda Fitment — compatible with an extensive list of Honda equipment including GX-series and GXV-series engines, EB, EG, EM, EX, EW, and EXW generators, HR and HRC lawn mowers, HS snow blowers, water pumps, tillers, tractors, and BF outboard motors, among others.
- Serial Number Verification Recommended — Honda supersedes carburetor components at specific production breaks, so always check your unit's serial number against the fitment table to confirm this is the correct set for your machine.
- Restores Idle Circuit Performance — a worn or damaged pilot screw disrupts the idle fuel circuit, causing stalling, hunting at low throttle, and difficult starting; replacing it with this OEM set restores stable low-speed operation.
The pilot screw — sometimes called the pilot jet screw or mixture screw — is the fine-adjustment needle that meters the fuel-air ratio through the idle and low-speed circuit of a carburetor. It controls how much fuel enters the engine at and just above idle, making it critical to smooth starts and stable low-throttle running. When the screw is worn, corroded, or damaged, the idle circuit loses its calibration, resulting in rough idling, stalling under light load, and hard starting that no amount of choke adjustment will fully correct; replacing the complete set returns the carburetor to its original metering baseline.
