Hoses and weber carb questions

Alright, well as i'd stated before i just purchased my B2200 an 88 model 2.2 it's got a new weber carb ( from redline not ebay ) and i have a runnning ac and would wish to keep it this way. I have taken pictures of some hoses and parts attached to the passenger side of my engine bay.




( In this one i capped a line that was open with a t connection i used small piece hose and capped it, the engine idled down and a lot of the rough idle was taken out


( All these hoses seem to be connected and ran to where they should be


Now you probably can't see it in this picture, but there was also another hose black with yellow lettering that i had capped off before doing the T connection, and the engine had idled down and roughness smoothed out slightly, but it smoothed out completly when i capped the T connection.

Now i'm just lookig to clean my engine bay up so any information on any parts/hoses that can be removed without affecting my acc would be appreciated thank you
