If your car bogs down exiting corners, your accelerator pump may not be pumping! When the throttle is opened all the way from idle, the accelerator pump should deliver a shot of fuel directly into the carburetor throat. If this shot is not visible (with the engine off), the diaphragm may have gotten stiff with age. A torn diaphragm will allow fuel to leak out of the carburetor. (Race gas may leave a tell-tale purple stain on the outside of the carb body.)
This diaphragm fits the Weber 32/36 DGV (including 5A), DGAV, and DGEV progressive carburetors as well as the DGAS/DGES synchronous carburetors. Not for DFV series.
Also available as part of the Weber 32/36 DGV Carburetor Rebuild Kit, Part No. 50-1588.
