The dizzy rotates in CCW direction looking down at the top. The port on the can pointing towards the back of the car is vac retard, it moves the advance plate in a CCW direction retarding the timing at high vac conditions. The port on the front of the can is boost retard, it moves the plate in a CCW direction under boost pressure to pull timing back from full centrifugal advance.
