The Honda 99101-ZDK-0680 Main Jet (#68) is a genuine OEM carburetor component designed for GX160 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the exact sizing and flow specifications that Honda engineers calibrated for this engine. The #68 designation identifies the orifice size, which determines fuel delivery rate — matching it correctly to your engine is essential for proper carburetor performance.
Key Features
- Correct Orifice Sizing — the #68 designation is a precise fuel metering specification; an incorrect jet size will result in a rich or lean condition, rough running, or poor throttle response
- Genuine Honda OEM Component — manufactured to Honda's exact tolerances, ensuring the fuel-to-air ratio the GX160 carburetor was designed to deliver
- Direct Carburetor Fitment — sized and threaded to install directly into the GX160 carburetor body without modification; verify part number 99101-ZDK-0680 against your engine's serial number and carburetor assembly before ordering
- Restores Proper Fuel Delivery — a worn, clogged, or incorrectly sized main jet causes hard starting, erratic idle, and loss of power under load; replacing it with this OEM jet returns the engine to correct fuel metering
The main jet is a precision-calibrated orifice inside the carburetor that meters the flow of fuel into the engine's air stream during mid-range and full-throttle operation. Its size — indicated by the number stamped on it, in this case #68 — controls how much fuel enters the venturi, directly affecting the air-fuel mixture and overall engine performance. When a main jet becomes clogged with varnish deposits or worn beyond its original dimensions, the engine will typically run lean, stumble under load, lose power, or refuse to reach full speed.
