I'm removing the unnecessary smog vacuum lines from my motor, and need to know where to hook up the vaccum advance and secondary vacuum break. I have included 2 pics with the ports labeled just like they are on the carb. Port E is to the PCV valve, Port G was hooked directly to the vacuum advance, but that may not be right. G gets its vacuum from below the throttle plate on the secondary side, so wouldn't that be the same as direct manifold vacuum? Port A goes to the primary vacuum break, port F is the bowl vent. Ports B,C,and D i'm not sure about.
