Carb Problems: Holley 1920:

I got some carb problems, and I know you guys have the answers.
I got a 1972 Dart with 225 and 904 and it had A/C.

I know there are several version of the Holley 1920. I think this someone place a newer carb that set for emissions and I think I need a standard Holley 1920. (If you have one for sale or Super Six setup or 4BBL upgrade let me know!)

I got alot of plug lines (I didn't do it, It was that is the way when I got it), but I want to correct it, just to make it work for now. I don't know where these lines go. I do have a book and tell me where it goes, but I want to know what you think.

Quick Questions:
-Where / What is a Carbon Canister?
-Where / What is a (OSAC) Valve?




Here are the model numbers:



Photo One:
Item I: Clog
Item II: Some type of valve
Item III: I think a spring is missing



Photo Two:
Item I: This doesn't look right to me. Need a pic of the correct ways.
Item II: Don't know.
Item III: Another clog line.
