I got out and messed around with it some more. I was disconnecting the wrong linkage

Anyway I disconnected the correct linkage and moved the vacuum proportioning valve until it was 10 mm from the stop. I could only adjust the vacuum to drop to 7.5 " Hg. During the test drive it seems that the car takes a little longer to shut off.

Is this an indication of the proportioning valve needing replacement?

thanks,
Jim
