To set the ignition timing correctly you need a timing light.

Should I just cap that line then? Or tee it off into the vacuum line for the distributor?
Then no, I did not. Once running I will prob drive it to a shop and let them do it

It should go into the canister, as designed.

The purpose of that whole setup is to catch expansion gasses from the fuel tank in a way that allows then to be burned up by the engine, instead of escaping somewhere into the air or worse.

Check those diagrams again, but no this should not be in the distributor circuit.

As far as the timing, is it dying because of low idle?

Loosen the distributor bolt just enough to allow movement with some resistance, start, make slow adjustments each way, and see if that improves things.

If the vacuum advance isn't working, that plus bad timing could easily be the reason it's stalling at idle.

I didn't take the canister out. The PO did and it did not come with the car.
It will not idle at all, so I don't know if it it because the idle is too low or not.

lol I know. All I did was leave the fan and tbelt cover off =p

And the car is in time now...
Just to be sure the vacuum line off the distributor goes to the port on the underside of the mani?

The car will run fine without the vacuum retard working. But you need to have ZERO open ports. Open ports = vacuum leak = poor idle

It will not run fine however if you're IAC is not working properly

I thought you called me a retard lmao...which would be the case after reading back through this thread.
I will try to plug any open ports I see. But as I remember, there were only two and they were plugged.

I plan on taking the IAC out today and cleaning it

You can test it on the bench if you can safely feed it ONLY +5v.

The iac is basically a valve. It doesn't pump air or anything. So when I check them I just disconnect the hoses and Key on engine off to and blow through the side the arrow is pointing away from and see if these a big restriction. You can also watch the motor do its thing with the hoses off

If it idled before this work, i think it's safe to say the fuel filter isn't the problem.

On a B21FT the small vacuum hose that is on the throttle body is T'd and goes to the distributor. This is ported vacuum which is how they want the distributor vacuum to function. It also gets boost retard that way as well.
