Have a look at the following picture from my 1500cc Ritmo (Strada) engine:
I'm thinking of the part surrounded with a yellow line. What exactly is it? What does it do, and what happens when it doesn't work?
It seems that originally, there were supposed to be two vacuum hoses connected to it, but when I bought the car, it looked just like on the picture above.
