If it's a later model 4160, there should be 2 small ports on the passenger's side front. The upper port (on the metering block by the idle mixture screw) is for ported vacuum advance. Below that, on the base plate, is the same size port that is unported manifold vacuum. Towards the rear of the carb on the sam side is a large port for PCV.
