1972 Plymouth Valiant 4 door Auto Slant 6
I could swear on my old manifold that was OPEN.
Shouldn't be. It's just a cast-in bowl.
I have that fitting and the other stuff that was in that hole was rotted out.
So you need the proper choke spring assembly. They vary by year, so make sure you get the right one. Or get the electric choke linked above.
I thought the carb was a potential issue. The old one has a core charge but I have NOT sent yet.
The carb is always a potential issue, and a carb that hasn't been run since 1985 definitely needs a rebuild, but a rebuild kit is a lot cheaper than buying a new carburetor, and if you rebuild it yourself, you know it's done right.
If the carb that was on it is original, then you should keep it because it is set up correctly for your engine. If you install a rebuilt carb, you are essentially guaranteeing that there will be at least one thing wrong with it, as they are assembled from bins of used parts, with minimal tolerances and standards.
The original carburetor should have a little stamped aluminum tag on one airhorn screw with a number, and that number should correspond to the appropriate number in the service or parts manual.
