green arrow is pcv port, do gasket and manifold hole match or did you notch gasket

The port to the left, I assume would run to the distributor (which is the exposed line with clamp to the far left). That is correct

Ok looks right. What year car and can you take picture of vacuum canister, two different ones,with and with out control valve. Is going to say to carb bowl vent. Your carb bowl vent is to open air no hose fitting. So on canister bowl vent conection just cap it
Hopefully I’m following your instructions correctly. I have a ‘74 Duster 225 automatic. Pictured first is the charcoal canister; the only thing with “Carb Bowl” labeled, and the second two pair of pictures is the vacuum amplifier. I apologize in advance if this isn’t exactly what was requested. Pretty green with this stuff.
The yellow striped line has no home currently from the vacuum amplifier.

Green arrow carb bowl vent cap it. No control valve visible,Red to purge port on carb
Uhhh, I have to ask, per pics in posts#16 & 24.....why is there no throttle return-spring on the throttle? Really should use a dual inner/outer set. Yet there is a throttle spring on the choke link clip? That's not going to work well for either!!
Funny you bring that up! I actually just got a new one. Lol Thank you for noticing!

Your carb has no purge port

No purge port or maybe it does. For the sake of discusion why not run purge line from canistor to anti ice system port. Carb does not know where air comes from, have to think about that
I had considered that, actually. I was concerned about the potential consequences. I may give that a shot when I get home from work.

potential consequences good point wont be fuel from carb bowl vent that only leaves over fill limiting valve. If thats working right should not be very much vapor from tank. But if stuck in open flow position could be a lot of vapor from tank. Caution is advised.
