The Honda 99101-ZC3-0620 Main Jet (#62.5) is a genuine OEM component designed for the EX350 inverter generator. As a direct Honda OEM part, it is manufactured to the exact specifications required for the carburetor in this generator, ensuring the correct fuel metering calibration for the EX350. Verify your unit's serial number against the fitment table before ordering, as Honda supersedes parts at specific serial breaks — confirming the match protects your repair.
Key Features
- Exact OEM Fuel Metering — a genuine Honda main jet sized at #62.5, delivering the precise orifice diameter the EX350 carburetor requires for correct air-fuel ratio at full throttle
- Direct OEM Replacement — sourced from Honda's own parts catalogue for the EX350 inverter generator, this jet installs directly into the carburetor without adaptation
- Serial Number Verification Recommended — Honda updates carburetor jetting at production serial breaks; always confirm part number 99101-ZC3-0620 against your generator's serial number in the fitment table
- Restores Clean Running — a clogged or wrong-sized main jet causes lean running, hesitation under load, or hard starting; replacing it with the correct OEM jet returns the generator to smooth, stable output
The main jet is a precision-calibrated orifice fitted inside the carburetor's main circuit. It controls the volume of fuel drawn into the airstream when the engine is running at mid to full throttle, and the orifice size — in this case #62.5 — is tuned specifically to the displacement and airflow of the EX350 inverter generator's engine. When the jet becomes blocked with varnish or debris, or is replaced with an incorrectly sized unit, the engine runs lean, loses power, surges, or refuses to start reliably; fitting the correct OEM jet restores proper combustion and stable electrical output from the generator.
