Question: I have two vacuum ports on the throttle body. One is right at the connection to the rubber intake boot, the other is under and a bit to the right of the idle screw. Does it matter which port the vacuum advance line is connected to?

UPDATE

Something's up with the distributor vacuum advance. It started (on its own) idling up at 1800 rpm again. I can pull the vacuum advance off and idle drops to a rock steady 1000. Re attach the vacuum line to the throttle and the rpm goes right back up.

I'm thinking the spring is weak on the advance diaphragm.

Is the advance diaphragm module available separately?

Thoughts anyone?
