Knox,
Are there any Emissions stickers on the front grill/radiator support? Like CEC or Air pump equipped? Or did the PO paint over them... God bless.

The Ca. model had a different type.

UPDATE: I rebuilt the carb as Jon In Tucson advised and it worked beautifully! Smooth idle and smooth at high rpms.

However I still have yet to do a full replacement of the vacuum lines because of a lack of a CTO or "ported vacuum switch" as a great deal of the important things were routed to it or from it. So I have ordered the part from Autozone and as soon as it gets here ill set to work on replacing all the lines.
