I have been scrubbing the posts trying to find some answers to timing. I have an Eddy 1405 sitting on my Performer RMP AG sitting on my mild 1975 318. The Carb has 2 vac ports on the base. One is 'Timed' and the other is 'Manifold'. Which one should my advance can be attached to??? When setting the initial timing, should the vac advance be disconnected? I see in other posts that my initial should end up in the 8*-12* range and that SHOULD put my total at 36ish. Does that all seem correct? or did I miss something crucial? Thanks to all of you for the great help.
