Okay, this is my rereiteration, many things learned. One, easy to go round in circles, almost like trying to align a car, one thing effects another effects another and so on. Best thing for me i realized was to go back to the original calibration and take another avenue.

Emulsions--.028-0-.028-0-.028. I felt there were too many or too much area so in the end just removed the second from the top.

IFR--I moved this restriction to the bottom of the well, smoother afr is supposed to be the result, so doing this necessitated a recalibration in this circuit as it effected the afr at idle and cruise.

.033/.070 with t slot restrictor of .043 on the primary side. If you can do the t slot restrictor it makes things so much easier in adjusting the lean cruise. On the secondary side the t slot can be larger as you are not cruising on it, just used for transition to the mains, .055 used here. .031/.067 was used with .046 restrictor on the primary also and worked good.

PV is now 9.5 on the primary side, 8.5 secondary. This adjustment can help alleviate the lean afr climb as you accelerate, bring the PV in at the highest setting without undue opening, idle is at 11". Also something I learned, the PV starts opening at the rated depression, it will take a bit before it is fully open, so if our light cars accelerate at a fast pace, you might want to lead it a little.

PVCR .0595, no change, possible change as the observed afr was 12.5 at full throttle.

HSB .035, dropped from .036

Squirter .031, no change

Accelerator cam white primary, pink secondary.

Recommend afr gauge and vacuum gauge for all adjustments.
