The Honda 99101-ZE8-0820 Main Jet (#82) is a genuine OEM component designed for GXV270 and GXV340 vertical shaft engines. As a direct Honda OEM part, it carries the exact orifice sizing Honda specifies for these engines, ensuring the fuel metering your carburetor was built around. This Main Jet (#82) is the correct replacement for GXV270 and GXV340 engines — confirm your serial number against the fitment table before ordering, as Honda supersedes jets at production breaks.
Key Features
- Exact Orifice Sizing — genuine OEM construction means the #82 calibration matches Honda's original fuel-metering specification for the carburetor, delivering the air-fuel ratio these engines are tuned to run on
- Direct OEM Replacement — this jet installs into the carburetor float bowl exactly as the original, with no reworking of threads or passages required
- Confirmed Fitment — listed for GXV270 and GXV340 vertical shaft engines; check your engine's serial number against the fitment table to confirm the correct jet for your production range
- Fuel Delivery Integrity — a worn or partially blocked main jet causes rich or lean running conditions, leading to poor power output, rough operation, or hard starting under load
The main jet is the precision-metered orifice inside the carburetor that controls how much fuel enters the engine at mid to full throttle. Fuel is drawn through the jet's calibrated bore by engine vacuum, and the size of that bore — designated here as #82 — determines the fuel-to-air mixture at operating load. When the jet becomes blocked with varnish deposits or wears beyond its original calibration, the engine runs lean or rich, resulting in loss of power, overheating, or excessive fuel consumption. Replacing a damaged or fouled jet with the correct OEM-spec part restores proper combustion and protects the engine from the damage that sustained incorrect fueling causes.
