Just to make sure, have the car at idle, and put a finger on each line. the Retard line is the one that will have suction at idle; the advance one will not.
To set the timing, you must unhook and plug both lines, set the timing to 5 degrees BTDC at idle, around 950 rpm. Then, hook up the idle retard line. It will make the car run noticeably different and you may have to reset the idle with the idle screw.
Also, check the timing with the retard disconnected, and with it connected, and note the difference. Where does the timing fall with the line connected?
If you have your timing set improperly there's a chance the retard line is making the timing fall too far out of spec.
Many folks will also tell you that you should set the 4000RPM timing to 25 degrees BTDC with both vacuum lines plugged and disconnected, and not really worry about where it falls at idle.

Gogar,
thanks for staying with me on this ...i will do the things you mentioned on tuesday afternoon and get back to you with the results....seems as though they are hooked up right then. when i did the timing i only unhooked and plugged the advance (red) and the idle was then hard to set right( had to turn it right) to raise the idle.
i hope you will check in tomorrow to see if i got it right.
thanks again and have a good evening, ben
