The Honda 99201-ZG8-1150 Main Jet Set (#115) is a genuine OEM component designed for GXV610 and GXV620 vertical shaft engines. As a direct Honda OEM part, this jet set is manufactured to the exact specifications required for proper fuel metering in these engines. Confirm fitment using the compatibility table and verify that the #115 sizing matches your carburetor's specification before ordering.
Key Features
- Correct Jetting for These Engines — the #115 designation identifies the metering size; OEM manufacture ensures the orifice diameter is exact, so fuel delivery matches the carburetor calibration Honda engineered for the GXV610 and GXV620.
- Genuine Honda OEM — sourced directly from Honda, this jet set carries the same part number 99201-ZG8-1150 used in Honda's own service network, so you know you are installing the correct specification.
- GXV610 and GXV620 Fitment — listed for GXV610 and GXV620 vertical shaft engines; Honda supersedes jet specifications at production breaks, so cross-reference your engine's serial number against the fitment table to confirm this is the right set for your unit.
- Fuel Delivery Integrity — a worn or incorrectly sized main jet causes rich or lean running, hard starting, and loss of power under load; replacing it with the correctly sized OEM jet restores clean throttle response across the RPM range.
The main jet is the precision metering orifice inside the carburetor that controls how much fuel enters the airstream at mid-to-full throttle. Its bore diameter is calibrated to the engine's displacement and air flow, so the air-fuel mixture stays within the correct range for efficient combustion. When a main jet becomes clogged with deposits or wears oversize, the engine runs erratically, produces black smoke, or loses power — replacing it with a correctly sized jet restores the carburetor's intended fuel curve.
