Just as a good example of the difference it can make...

Skip to the middle/end to hear the god awful idle... It also had a lot of trouble starting. (Video taken sunday)

After I found the ridiculous leak in the manifold... It's now idling at a perfect 1k rpm since this last video

And the leak was... where, exactly?

 

Intake manifold, engine side.

 

Well done. Those can be hard to isolate.

 

Thats great!
How did you find the leak? like what did you go about doing? And was it the gasket? I am dealing with very lean idle and stalling but will rev great. The car was idleing like a champ not to long ago. Idk if i should rebuild the carb i just cant find any vacuum leaks.
