Glad things improved a bit. I don't have the CPR plumbing memorized, but I know from experience that the "Control Pressure" is always LOW for a cold start (down around 20 psi in winter), then rises to about 55psi when warm (always 10-15 psi below System Pressure).

Lower control pressure on the Control Plunger allows the plunger to rise more (for a given air flow). This results in a richer mixture. The CPR doesn't really control "Fuel Pressure" at all. That is basically "fixed" by a "Line Pressure Regulator" in the Fuel Distributor.

By the way, Niel is talking about a V6 (or Turbo), with the Air Flow unit that is upside down compared to yours. Much easier to see and adjust, for sure.
