Choke Diaphragm for Weber DHTA Carburetors.
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 over the years, a variety of these diaphragms were used which are not necessarily interchangeable.
This particular diaphragm has a stalk that stands 53.5 mm tall, measured from the top dish.
Required quantity per carburettor: 1
