This is a replacement diaphragm designed for the accelerator pump circuit on classic Weber carburetors. The diaphragm's function is to inject an extra squirt of fuel into the carburetor throat when you press the accelerator pedal, preventing the engine from running momentarily lean during rapid acceleration. A defective, cracked, or dried-out diaphragm will inevitably cause the engine to hesitate, stumble, or bog down when you open the throttle. Replacing the diaphragm is a simple and highly effective way to restore a crisp and reliable throttle response.
