Interested in what Richard Salt refers to as “the crude mechanical/vacuum system”, are you refering to the V12 ?
Do we mind if we expand the discussion to the V12 vacuum system ? My CC doesn’t function but its not important to me so I haven’t looked at it yet. On the other hand I do like all parts of a car to function properly so maybe this will trigger me to action ! I am hands on.
So Richard please let me/us in to the secret, where are these “tiny brass strip flap valves” and the “big vacuum cylinder” too please.
