The Honda 99101-ZK7-0620 Main Jet (#62) is a genuine OEM carburetor component designed for a wide range of Honda engines and power equipment, including GX120 and GX160 horizontal shaft engines, GXV160 vertical shaft engines, WB20 and WB30 water pumps, WT20 and WT30 water pumps, WH15 and WH20 water pumps, F401 and F501 tillers, HRA215, HRC215, and HRC216 lawn mowers, WD20, WD30, WMP20, and WP20 and WP30 water pumps, and the HP400 power carrier. As a direct Honda OEM part, part number 99101-ZK7-0620 carries the exact calibration required for correct fuel metering across all listed applications. Because Honda supersedes jetting across serial ranges, confirm your unit's serial number against the fitment table before ordering to ensure this #62 sizing is correct for your specific machine.
Key Features
- Exact Jetting Calibration — the #62 orifice size is factory-specified for correct fuel-to-air metering; an incorrect jet size causes rich or lean running, power loss, or difficult starting
- Genuine Honda OEM Quality — sourced directly from Honda, this jet meets the same metering specification as the original, ensuring the carburetor delivers the right mixture under load
- Broad OEM Fitment — listed for GX120 and GX160 horizontal shaft engines, GXV160 vertical shaft engines, multiple Honda water pump models, tillers, lawn mowers, and the HP400 power carrier, including models such as the WT30 and WB30
- Verify Before Installing — Honda updates jet specifications at serial number breaks; always cross-check your machine's serial number against the compatibility table to confirm the #62 is the correct size for your carburetor
The main jet is the precision metered orifice inside the carburetor that controls how much fuel enters the main circuit under normal running and load conditions. Its calibrated hole size — in this case #62 — determines the fuel-to-air ratio the engine runs on: too small and the engine runs lean, overheats, and loses power; too large and it runs rich, fouling the spark plug and burning excess fuel. When a main jet becomes clogged with varnish deposits or worn out of spec, the engine will stumble under load, idle poorly, or refuse to reach full power, and cleaning or replacing it with the correctly sized OEM jet restores proper carburetor function.
