The Honda 99101-ZE8-0880 Main Jet (#88) is a genuine OEM component designed for the GXV340 vertical shaft engine. As a direct Honda OEM part, it carries the exact sizing and calibration specified for the GXV340 carburetor, ensuring the fuel metering characteristics match what Honda's engineers originally intended. Honda supersedes carburetor components at serial breaks, so confirm your engine's serial number against the fitment table before ordering to make sure part number 99101-ZE8-0880 is the correct jet for your unit.
Key Features
- Exact Fuel Metering — a genuine OEM #88 main jet delivers the precise orifice size the GXV340 carburetor requires for correct air-fuel ratio across the engine's operating range
- OEM Calibration — sourced directly from Honda, this jet matches the original specification without the guesswork of an uncalibrated substitute
- GXV340 Fitment — engineered specifically for the GXV340 vertical shaft engine; always cross-reference your serial number with the fitment table to confirm applicability
- Engine Performance — a correctly sized main jet keeps the engine running cleanly at full throttle; a worn, clogged, or incorrectly sized jet leads to rich or lean conditions, hard starting, and loss of power
The main jet is the small, precisely drilled orifice inside the carburetor that meters fuel flow into the engine's air stream at mid to full throttle. Its calibrated bore size — in this case #88 — controls how much fuel mixes with incoming air, directly affecting power output, fuel consumption, and exhaust cleanliness. When a main jet becomes clogged with varnish deposits or is replaced with an incorrectly sized unit, the engine will run lean or rich, resulting in rough operation, overheating, or a significant drop in available power.
