The pin/screw that penetrates and lodges in the refrigerant cylinder is too thick and blocks the outlet (to the side) path of the valve. Stevie Wonder could see it, but obviously not the genius who "designed" it. After sharpening the screw/pin everything worked. Wasted refrigerant and a lot of time to get it working and re-vacuum throughout the system.
