So I am prepping to intall my original OEM carb re-built by Jim C into my desmogged '78 as per Jim C's de-smogged diagram. This thread is pic heavy. There appears to be three vac ports on passenger side of carb. I am certain one of these is for the vac advance connection from the dizzy. One of the others I need to connect to the Lower brown BVSV connection but which one?? Also which one should connect to the vac advance on the dizzy?? I assume the third one on the passenger side should be capped off?
Also the larger downfacing port on the front of the carb-what connects there or should it be capped off for Jim's de-smogg setup? The front three tubes, are they just tubes or do they go into front of carb?? Are these front three tubes just for routing vac lines? The '80 Aisan non-USA carb on my rig now has the stud bolt that goes upward thru the top of the air cleaner housing connection with the wing nut on top. As my original pictured one does not have this can I just unscrew the one of the '80 Carb and install it on the one pictured? Never done this so I appreciate all the input.
