MG MGA - carburetor damper

Hi all
My actual dampers are ACU8114 (short piston) with a ventilation hole in the hex brass cap. Carburetors are internally ventilated though, therefore I need a damper that is not vented, i.e. no hole in the damper cap. However it seems impossible to find this combination on the market. Were non-vented ACU8114 ever available? Can anybody help?

Andre, You can easily block the existing holes by soldering them. Five minute job.

I bought unvented brass caps from Burlens in the UK. I actually needed the vent hole so I had to drill them out.

Frank: I also thougt of that but didn't want to mess around the originals.
Steve: Did you get the older version of piston or the improved one (shorter piston)? See image.

I transferred what I had to the new cap (see photo).

Hi all
Here I have the answer to my question:

"Dear Sir
Thank you for your enquiry.
The AUC 8114 vented damper has an identical damper but non vented (dust proof part number AUC 8115.
I hope this helps.

This helps for sure!
