The Honda 99101-ZDK-0700 Main Jet (#70) is a genuine OEM carburetor component designed for GX200 horizontal shaft engines. As a direct Honda OEM part, this jet is sized and calibrated exactly to Honda's specification for the #70 orifice, ensuring the fuel metering your engine depends on is restored to original design parameters. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes carburetor jets at serial breaks and the correct size must match your specific unit.
Key Features
- Correct Fuel Metering — the #70 orifice size is precisely calibrated to deliver the fuel-to-air ratio Honda specified for the GX200 carburetor; an incorrect or worn jet causes rich or lean running, poor throttle response, and hard starting
- Genuine OEM Part — sourced directly from Honda, part number 99101-ZDK-0700 matches the original jet in orifice diameter and thread pitch, dropping straight into the carburetor bowl without adaptation
- GX200 Fitment — listed for GX200 horizontal shaft engines; verify your serial number against the fitment table to confirm this is the correct jet size for your carburetor variant
- Restore Clean Combustion — a clogged, damaged, or wrong-sized main jet starves the engine at full load or floods it at idle; replacing it with the correct OEM jet brings fuel delivery back into spec
The main jet is a precisely drilled brass metering component seated inside the carburetor body. It controls the volume of fuel delivered to the engine at mid to full throttle by restricting fuel flow through a fixed orifice — in this case, a #70 bore. When the jet is clogged by varnish deposits or damaged, the engine runs lean under load, surges, loses power, or fails to reach full rpm. Replacing the main jet with the correct OEM size restores the fuel delivery curve the engine was tuned for, bringing combustion efficiency and throttle response back to specification.
