Changed the IA head back to the rebuilt stock SC head. I had to re-rebuild the SC head...wrong o-rings. Now, The car runs at least, starts cold and hot and seems more stable. It is a bit lean, so I am tweaking the control pressure. My issues are now 180 degrees aff than with the IA head. Now, I have way overrich idle, and lean mid range. Also, the air plate assembly from my original SC/IA combo was a bit different than the one I am now using...the piston tip protruded a bit more from the one I have on now, so when I simply changed the fuel head, the geometry of the piston covering and uncovering the slits changed.

I am sending the IA head back for recalibration.
