Why doesn't the Dist vac need to be hooked up. What is it's fucnction. Does it hurt to be hooked up to the remaining port in the front of the carb.
Your distributor appears to be an emission distributor, it has Vacuum Advance
and Vacuum Retard
. Vac retard is an emission "feature". I would not hook it up and I would have to research how to correctly hook it up if I was.
The hose with the white tape on it in your picture appears to be the advance. It is easy enough to check when you get it running. BTW set the timing with the hose off and plugged. Then when you hook it up to manifold vac you should see the timing advance, if it retards move the hose to the other nipple on the distributor and see if it advances then. The outer one SHOULD be advance though unless there is something odd about the particular distributor.
Also there has been some debate
about whether Vac Advance should be hooked to manifold
vac. Once you verify the advance is working, you can move it between the two ports on the front of the carb and see if it gets better economy or performance one way or the other, but manifold usually works best for me.
Ahh I see your kickdown lever in the picture now, it should go to the lever with the spring on it NO?
You should be able to get a NPT nipple at one of the box auto parts store, maybe in the "Help" section?
