The Honda 99101-ZC3-0680 Main Jet (#67.5) is a genuine OEM component designed for EX350 inverter generators. As an OEM part sourced directly through Honda's parts program, it carries the exact calibration required by the factory carburetor. This Main Jet (#67.5) is sized to the #67.5 specification, and buyers should confirm that designation matches the jet currently installed in their unit before ordering.
Key Features
- Exact OEM Calibration — as a genuine Honda part, this main jet is drilled to the precise #67.5 orifice size the EX350 carburetor requires for correct fuel metering at full throttle
- Direct Carburetor Fit — this part installs into the carburetor's main circuit without modification, replacing the original jet on a like-for-like basis
- Variant Confirmation — the #67.5 sizing is a specific calibration; verify part number 99101-ZC3-0680 and the jet size against your carburetor before purchasing, as multiple jet sizes may be listed for the EX350
- Restored Fuel Delivery — a worn, clogged, or incorrectly sized main jet causes rich or lean running, rough operation under load, and poor fuel economy; replacing it with the correct OEM jet restores stable output
The main jet is the primary fuel-metering component in a carburetor's main circuit. It is a small brass fitting with a precisely sized orifice that controls how much fuel enters the airstream when the engine is running at mid to full throttle. In an EX350 inverter generator, correct fuel metering directly affects combustion quality, load-handling stability, and the clean power output the inverter stage depends on. A jet that is clogged restricts fuel flow and causes lean-running hesitation under load; one that is oversized or worn results in rich running, excessive fuel consumption, and black exhaust smoke.
