Hey everyone.

I've spent the last few months tinkering with a 1980 SA that had just under 100k KM on it. Weird, because it came with a seized FB engine--failed swap? The wiring harness on this car is mint, and the thing is on a set of original effing tires, made in 1979.

Anyway, I rebuilt the carb and put in a used SA engine, but the problem is, I was drunk when I pulled everything apart. Specifically, the carb vacuum/coolant lines and one piece of throttle linkage are giving me a headache. It's a Canadian car, so it's slightly different in a few ways, I believe.

The subzero starting fluid--does this go to the line that's right between the lines for the OMP? It has a very small diameter hole in it. (circled in white)

There's a nozzle coming out of the intake manifold, I think. Is this for coolant? It's clear plastic and attached with a bolt fitting. I can't find what coolant hose would go to this. (circled in red; I originally hooked the subzero line to this)

Also on the intake manifold, there's a line that's capped off, and I don't know what it's for. (circled in green)

There's a line coming out right next to the air and mixture adjust screws. It's larger in diameter than the lines on the rat's nest--maybe this one goes to a solenoid directly? I've only got two solenoids on my nest. (circled in orange; solenoid is circled in pink)

The thermal reactor and all the exhaust lines are bone stock and I want to leave them on for now, so I'm pretty sure I need most of these lines hooked up as well.

There's a diagram on the hood which isn't very detailed, and there is a service manual I found that labels most of the lines, but I can't find any of these labeled clearly.

Also: on the side of the carb with the throttle cable, there's one long arm that doesn't seem to go to anything. I believe it's connected to the secondaries, but I could be wrong. It can pivot in a few places.

Pictures below. I need to get this on the road so I can park my FD... the fuel consumption can't be justified in the rainy season.



Just out of view in the top right is a "vacuum sensing tube" for the throttle opener. I'm not sure whether this goes directly into the carb/manifold, or rat's nest.

Any help is greatly appreciated. Thank you.

Dig through this section in the 1980 factory service manual.

Zoom in on my carb. I think it shows the cold start where you have the yellow.

Thanks for the reply!

I don't know how I missed it, but the diagram I wanted was on page 30. I swear I've read through the emissions part twice and didn't see it--my mistake.

That just leaves one question. The subzero fluid connects to the line beside the air and mixture adjustment screws, so what connects to the line that's in between the two OMP lines? Nothing?

EDIT: According to this thread: https://www.rx7club.com/build-thread...ct-gus-944889/

The line between the OMP lines IS for the subzero fluid. I think the other line actually goes to the rat's nest. My mistake.

Now I just need to figure out the linkage and I'm good to go.

EDIT:
Nevermind, I still have no idea what these two do. I have a spare base plate and it looks like the line next to the mixture adjust screw goes right to the chamber, under the throttle plates.

I don't have a spare intake manifold so I can't see what the nozzle is for. I've went through the diagram and I know where everything goes except for these two lines.



Are these supposed to be connected to eachother...?



It looks like this is supposed to go somewhere, but it's not in the emissions or cooling diagrams anywhere.

What's the purpose of this?

The arm in the last pic controls the throttle plate/flapper.

The two red circled things actually connect to one another. The plastic piece is easy to break.

The linkage connects to the choke on top of the carb, here's a pic from when I was taking mine apart:
