The Honda 99101-ZDK-0650 Main Jet (#65) is a genuine OEM replacement designed for GX160 horizontal shaft engines, GXV160 vertical shaft engines, and HRC216 lawn mowers. As an authentic Honda part, this main jet is manufactured to the same specification as the original, ensuring correct fuel metering and air-fuel ratio for consistent engine performance. Honda supersedes parts at serial number breaks, so verify your machine's serial number against the fitment table before ordering to confirm part number 99101-ZDK-0650 is correct for your unit.
Key Features
- Correct Fuel Metering — the #65 orifice size is a critical specification; this genuine OEM jet delivers the precise fuel flow the carburetor was calibrated for, keeping combustion clean and efficient.
- Direct OEM Replacement — manufactured by Honda to original specifications, this jet installs directly into compatible Honda carburetors without modification.
- Broad Fitment — listed for GX160 horizontal shaft engines, GXV160 vertical shaft engines, and HRC216 lawn mowers, including multiple serial ranges within each model.
- Serial Range Awareness — Honda releases updated jets at production breaks; check your machine's serial number against the compatibility table to confirm this is the correct jet for your engine.
- Restored Throttle Response — a worn, clogged, or incorrect main jet causes rich or lean running, hard starting, and poor throttle response; replacing it with the correct #65 jet restores normal carburetor function.
The main jet is a small brass metering orifice seated inside the carburetor's fuel bowl. It controls the volume of fuel drawn into the engine under load and at higher throttle positions — the number stamped on the jet (in this case, #65) refers to the diameter of that orifice, and it is matched precisely to the engine's displacement and carburetor design. When a main jet becomes clogged with varnish or debris, or when the wrong size is installed, the engine will run lean or rich, resulting in loss of power, excessive fuel consumption, rough running, or difficulty reaching full throttle. Replacing it with the correct genuine OEM jet restores proper fuel delivery and engine response.
