Part-Load Enrichment Diaphragm for a Solex PBISA carburetor.
Following ancient "Solex Tradition", there are no lists of which diaphragm was used in exactly which version of the Solex PBISA carburetor...
The version with a spring-loaded stem can be found HERE but apart from that one, we have been able to identify 3 different versions of the "flat diaphragm".
The differences in these 3 versions can be found in the diameter of the collar around the little notch.
You can purchase the desired verson by selecting it through the Version ? * drop-down menu just above the Add to cart button.
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.
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
