The Honda 16950-ZM0-003 Petcock Assembly is a genuine OEM fuel shutoff component designed for a wide range of Honda engines and power equipment, including GCV160, GCV190, GXV50, GXV57, GSV190, GC135, and GCV135 engines, HR-series lawn mowers including the HRX217, HRN216, HRC216, and HRR216, and HS520 and HS720 single-stage snow blowers. As a direct Honda OEM replacement, this Petcock Assembly is manufactured to the same specifications as the original part it replaces, ensuring a correct fit without the guesswork of sourcing a compatible substitute. Confirm your unit's serial number against the fitment table before ordering, as Honda introduces part changes at serial break points across its engine and equipment lines.
Key Features
- Genuine Honda OEM Fuel Control — manufactured by Honda to exact original specifications, delivering consistent fuel flow and reliable shutoff action across the full range of compatible engines and equipment
- Correct Fit for a Broad Honda Lineup — covers GC135 horizontal shaft engines; GCV135, GCV160, GCV170, GCV190, GCV200, GSV190, GXV50, and GXV57 vertical shaft engines; HR215, HRA215, HRB215, HRB216, HRC215, HRC216, HRM215, HRN216, HRR216, HRS216, HRT216, HRX217, and HRZ216 lawn mowers; and HS520 and HS720 single-stage snow blowers
- Serial Number Verification Recommended — Honda updates and supersedes parts at specific serial breaks, so check your machine's serial number against the compatibility table to confirm this is the correct assembly for your unit
- Fuel System Integrity — a properly functioning petcock controls fuel delivery to the carburetor and prevents fuel from flowing when the engine is shut down; a worn or leaking petcock can cause fuel seepage, flooding, or a no-start condition
The petcock assembly is the manual fuel shutoff valve mounted in the fuel line between the tank and the carburetor. It controls whether fuel flows freely to the carburetor, is held back for storage or transport, or is diverted for reserve. When the valve seat or internal seal wears out, the petcock can develop a slow leak, allow uncontrolled fuel flow, or fail to shut off completely — leading to fuel flooding the carburetor, a flooded engine, or a fire hazard during storage. Replacing a faulty petcock assembly with a genuine Honda part restores clean, controlled fuel delivery and proper shutoff function to the engine or equipment.
