The Honda 99101-ZE8-0800 Main Jet (#80) is a genuine OEM component designed for the GXV270 vertical shaft engine. As a direct Honda OEM part, it is manufactured to the exact sizing and flow specifications the GXV270 carburetor requires. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes carburetor jets at production breaks and the #80 sizing must match your specific carburetor application.
Key Features
- Exact Fuel Metering — the #80 orifice size is calibrated to deliver the correct fuel-to-air ratio for the GXV270 carburetor; an incorrect jet size causes rich or lean running conditions that affect power and fuel consumption
- Genuine OEM Construction — sourced directly from Honda, this jet is manufactured to the same specification as the original, ensuring consistent metering performance without substitution risk
- Direct Carburetor Replacement — this part installs directly into the GXV270 carburetor body with no modification, restoring correct fuel delivery after wear, blockage, or damage to the original jet
- Serial Number Verification Recommended — Honda issues jet supersessions at engine serial breaks; check your GXV270 serial number against the compatibility table to confirm part number 99101-ZE8-0800 is the correct fit for your unit
The main jet is a precisely sized brass orifice located inside the carburetor's main fuel circuit. It meters the volume of fuel drawn into the venturi under mid-to-full throttle operation, directly controlling the engine's air-fuel mixture at higher loads. When a main jet becomes clogged, worn, or is replaced with an incorrect size, the engine will run erratically, lose power under load, run excessively rich, or fail to reach full operating speed — making this small component critical to consistent GXV270 performance.
