I've been trying to work this out myself in my head and on paper and I'm just stuck. Here's my vacuum connections right now- I know the egr valve is part of an adapter plate under the carb and it seems like I can just close off all the egr related holes and leave the spacer where it is without affecting much. But what I can't figure out exactly is what can stay and what all gets thrown out with the egr? Where is my vacuum amplifier and what does it do? Is that the same as my vacuum canister or is that the reservoir listed? What do I need to keep for the car to still run correctly? The spark delay/vacuum advance/intake manifold connection through the pvs valve seems like a necessity. Can I lose the temperature controlled vacuum valve completely? The venturi boost system is all part of egr from what I understand so it can go. What do I need to keep for my vacuum powered controls inside the car to work? Is it even possible to remove the egr from an a/c car? I'm sorry for the rambling deluge of questions, but my head is swimming here.
I added factory AC and have no EGR... Better to ask not what you can remove, but what you need to keep. What they're calling "spark port," straight to the vacuum advance. Cap the other ports on the carb. Manifold vacuum to the transmission and to the reservoir/AC. Also power brake if you've got it. Cap the other manifold vacuum ports. Everything else on that diagram should be ok to lose.
I appreciate your concise answer, but have one more dumb question- which one goes to the transmission? is that what the vacuum amplifier means? or is the amplifier not needed anymore? I couldn't even find it when I looked at my engine last.
Eh, sorry, maybe too concise. Like he said, to the modulator. A rubber hose goes from the transmission modulator on the trans itself to a metal line that goes up the firewall, to another rubber hose that should be plugged into manifold vacuum.
