The Honda 16950-797-A01 Petcock Assembly (English) is a genuine OEM fuel shutoff valve designed for GX630, GX660, and GX690 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the same specification as the original component, ensuring a proper fit and consistent fuel control. This petcock is the English-labeled variant — confirm that your machine calls for this version before ordering, as Honda lists this engine series with more than one petcock configuration. Verify your engine's serial number against the fitment table to confirm part number 16950-797-A01 is correct for your unit.
Key Features
- Genuine Honda OEM Fuel Control — built to the same specification as the original petcock, delivering consistent on/off/reserve actuation and a leak-free seat that an aftermarket substitute may not replicate on high-displacement GX-series engines.
- English-Variant Labeling — this assembly carries English-language markings; Honda lists more than one petcock variant for this engine family, so match this designation to your unit's original part before purchasing.
- Fits GX630, GX660, and GX690 Horizontal Shaft Engines — sourced directly from Honda's parts catalog for this engine family; check your serial number against the fitment table, as Honda supersedes parts at serial breaks within a model line.
- Leak-Free Fuel Shutoff — a correctly functioning petcock allows the operator to cut fuel flow during storage or service, preventing carburetor flooding and fuel seepage; a worn or cracked valve body can result in uncontrolled fuel delivery or persistent fuel odor.
The petcock assembly is the manual fuel shutoff valve mounted on the fuel tank. It controls the flow of gasoline from the tank to the carburetor, giving the operator the ability to stop fuel delivery when the engine is not in use, during transport, or for service work. When the petcock fails — through a cracked body, a worn seal, or a stuck valve — fuel can leak past the shutoff or flow unchecked to the carburetor, causing flooding, hard starting, or fuel odor during storage. Replacing a faulty petcock with a genuine Honda unit restores positive fuel control and keeps the engine ready for reliable operation.
