Part-Load Enrichment Diaphragm Solex 32 PBISA carburetors as used on, amongst others, the Citroen Visa 1100 and Peugeot 205.
These diaphragms now tend to suffer from age and the ravages of aggressive modern fuels which causes the "rubberized textile" material to harden and even crack, causing erratic running of the engine and fuel leaks.
Replacing the diaphragm is then the only sensible option.
As visible in the pictures, this is the diaphragm that has a spring-loaded stem.
Other, "flat", versions can be found HERE.
Please note that not every Solex PBISA is equipped with this diaphragm!
This product is priced, and sold, as a single unit.
Required quantity per carburetor: 1
