The US dual connection "pressure box" (I guess that is what the factory calls it.) that only has Retard via Boost or Vacuum. The inside or connection closest to the dist is vacuum retard and the outside is Boost-Retard. The pressure box only pushes in toward the dist. So pushing in toward the dist seems to be retard.

From the construction of the pressure box it looks like in can only move away or pull at the dist based on it construction as the internal diaphragm is at the seam. I looks like it is on the other side of the dist thus it looks like it must be a Vacuum Retard pressure box.

Do I have this right or did I mess it up. Dose this look like the case to anyone else?
