I have a 1986 Ford Taunus GL.
I want to ask for help about vacuum advance source for the distributor. What must be the source for vacuum chamber on the distributor? Will it be ported vacuum (from the carbureteur) or manifold vacuum or just a combination of both?
I have a thermal vacuum switch installed under the inlet monifold (original! surprised me). It has three ports. One is for the input of ported (carbureteur) vacuum, one is for manifold vacuum and one is for output to the distributor (I think) or to the pneumatic control unit (because I have an original air condition on my ford). Do I have to use this for the vacuum advance source or do I have to use ported vacuum from the carbureteur?
