Walbro Carburetor Diaphragm Assembly

The Walbro Carburetor Diaphragm Assembly is a replacement diaphragm, also called a carburetor diaphragm or metering diaphragm. It is used in diaphragm-style carburetors. Walbro is a well-known maker of carburetors, fuel pumps and fuel system components for small engines and powersports equipment.

Key Features:

• Flexible diaphragm that responds to engine vacuum pulses to help regulate fuel flow in the carburetor
• Built for use with gasoline and the fuel blends common in small-engine applications
• Helps restore smooth idle, throttle response and consistent fuel metering when the original diaphragm is worn, stiff or torn
• Designed as a direct replacement part for Walbro carburetor service and rebuilds

A worn diaphragm can cause hard starting, rough running, stalling or poor performance. Replacing it is a common step in carburetor maintenance and rebuilds. Choose the variant that matches your carburetor.
