The Honda 99101-ZC3-0700 Main Jet (#70) is a genuine OEM component designed for the EX350 inverter generator. As a direct Honda OEM part, this main jet carries the same specifications as the original, ensuring the carburetor meters fuel at the correct rate for the engine's design. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks.
Key Features
- Correct Fuel Metering — the #70 orifice size is calibrated to Honda's specification for the EX350 carburetor, maintaining the proper air-fuel ratio the engine relies on for steady output
- Genuine OEM Part — sourced directly from Honda, this main jet matches the original in orifice diameter and thread form, so it threads directly into the carburetor body without rework
- Single-Model Fitment — listed for the EX350 inverter generator; verify part number 99101-ZC3-0700 against your unit's serial number to confirm this is the correct jet for your carburetor
- Restore Clean Running — a worn, clogged, or incorrectly sized main jet causes rich or lean running, rough idle, and poor load response; replacing it with the correct jet restores crisp throttle response and stable power delivery
The main jet is a small precision orifice installed in the carburetor body that controls the volume of fuel drawn into the engine under load. Its calibrated bore size determines how much fuel enters the air stream at mid-to-full throttle, directly affecting power output, fuel consumption, and emissions. When the jet becomes clogged with varnish deposits or is damaged, the engine runs lean or rich, resulting in hard starting, surging, or loss of power under load.
