Hi, I'm just replacing my solex CD175 carbs with SU's and need some advice about re-connecting the vacuum advance pipes. On the solex there were
2 connections on the carb (on the inlet manifold flange) top and bottom, top one went to the "vacuum delay device" then to advance device, and the bottom connection via the fuel trap to the back of the vacuum advance gizmo.Now, the SU's have only 1 connection (on top of manifold flange thingy), I know I need to connect the right tube in order to make the advance actually move, this I can easily test by sucking on the tube, but what about the other, now spare, tube?
Despite the name being seemingly self explanatory, what exactly does the vacuum delay device do?
Thanks,
Andrew
