I have two problems. The first being: I have a 2BBL Holley carb (fresh rebuild) that has an open vacuum port (threaded fitting), on the bottom-left corner beside the choke. This port was NOT plugged, or plumbed into anything. Should it be drawing vacuum or not?
Secondly: With this obvious vacuum problem solved, what is the procedure setting the base timing, for a 'points only' (non-electronic) distributor? I've read dozens of threads, but all seem to have electronic advances. I only have the 2 wires, running to the coil.
