Rubber cup assy

The carb mounting nuts should be tightened to compress the rubbers until a gap of approx 1mm remains between the steel caps - this should give the correct torque to allow an air tight seal on the MISAB manifold seals & enough flex for efficient absorption of the engine vibration.
Dampens vibrations and leaves the carburettors a little movement space.
The most commonly used in DCOE Weber carburetors.
The set includes 1 rubber washer 1 and 2 zinced steel washers.
