"B" is not a vacuum port for PCV. That is air inlet to open the choke. There is a "U" shape line that is missing and is connect to a tube(missing) that is pressed just above choke housing. Inserting a plug will prevent the choke flap not to open at start up.
"A" Is not just for the brake booster, It's also the PCV vacuum port.
