Zama Nozzle Assembly Check Valve Carburetor

Zama nozzle assembly check valves, also called main nozzle check valves or check valve nozzles, are replacement carburetor components for Zama diaphragm carburetors. They are used on small engines in outdoor power equipment such as chainsaws, string trimmers and blowers.

Key Features:

• Genuine Zama replacement part for Zama carburetors
• One-way check valve in the main nozzle keeps air from entering the metering chamber during primer operation
• Supports the idle circuit, priming, and consistent starting
• Available as pressed-in or screw-in nozzle styles, depending on the carburetor

If the check valve sticks or leaks, symptoms can include hard starting, a carburetor that won't prime, and an unstable or lean idle. Replacing a worn nozzle assembly can restore normal carburetor operation. During service, don't insert tools into the small check valve orifices, because that can damage the valve. Zama is a major carburetor manufacturer for the outdoor power equipment industry, and these parts are built to the same standards as its original equipment.
