Re: Trouble with idle and vac. line

My problem is that with the retard vac. line connected to the dashpot, the idle drops way low and almost stalls the engine. It is hunting just like it has a vac. leak. With the vac. port on the throttle plugged, it idles well, but too high (1200RPM). Idle speed screw is all the way in. No other vac. leaks that I can find. Timing is dead on.

I haven't checked the gap for the Ignitor yet. Any ideas?

Check the ignitor gap and timing first.
Hunting is a result of lean idle mix and you have the idle screw in all the way! Check for vacuum leaks!
If the retard hose is plugged in, timing spot on, you should be able to adjust the idle speed with the idle bypass screw with no problems. If you can't, something is goofy like a vacuum leak or the timing is set wrong.
Check the AAR valve also after it warms up as it might be sticking open.
