Question 2, High Idle - yet again Options

[BenNC]

I know, there have been a gazillion posts about high idle. Most of them seem to end with check al the hoses and set the timing.

I have replaced all the hoses, and set the timing. With the idle adjust screw all the way clockwise I idle at about 1800 rpm. Per my Haynes manual, turning the screw counterclockwise whould lower the speed, butthe idle increases for me. Is this an error in the book, and what should I look at next.

By the way. It idled fine until the points of undetermined age froze on me. It idled fast with new points and has continued with the new Pertronix.

Thanks

If the screw on the throttle body doesn't slow it down:
1. AAR valve stuck open
2. Vacuum leaks or misplaced hose
3. Vacuum retard hose is not set up right
4. Timing way advanced
Plug AAR hose first.
Warm up car, disconnect and plug the hoses to the dizzy. Set the timing to 27 degrees BTDC. Hook up dizzy hoses, idle should drop. Reset idle with the AIR BYPASS screw on the throttle body and set mix on the ECU.
If its still high check for leaks with small amounts of starting fluid spray.
