What do these Carb hoses do?

View attachment 154199 Pointed out in this picture, on my 72 Newport there is a hose missing on the air cleaner. On the bottom of it, there are two hoses that are cut off, one of them goes into the back of the carb (plugged off) and one goes to the red circle in the picture. They connect at a part that sticks up next to the carb. What are these for? Should I reconnect them? The car sometimes is a little slow from a stop, but can still haul ass and is hard to start cold especially if it...
