(30) Complete Choke Diaphragm for Weber DAT Carburetor 47407.133

Complete Choke Diaphragm for Weber DAT 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.

This is the "complete" version of the diaphragm.

Please note that when you order this diaphragm, you get the diaphragm as shown in the picture, with the springs and plastic parts.

In case the plastic parts, spring etc are still salvageable, you could opt for purchasing the "bare" version of this diaphragm and transplant those small parts onto the new one.

This particular diaphragm has a stalk that stands 53.5 mm tall, measured from the top dish.

Required quantity per carburettor: 1

This is numbers 30 in the drawing.
