Cone Rubber met 2 Stalen Cups

Rubber Cup assembly for Weber DCOE & Dellorto DHLA Carburettors (CSA005)

This rubber cup washer is an alternative to the thackery washer which was designed to reduce high fequency vibration in the carburettors and prevent throthing.

Throthing causes the floats to rest on the throth and not the actual fuel level leading to the engine running lean.
