Verify cam timing is correct.

Insert jumper to advance circuit (white covered 2p jumper plug on the d-side fender near the strut tower, insert something to cross those pins, like a safety pin)

Loosen dizzy and attach timing light, check/adjust timing as necessary.

Idle speed is not adjustable, the IACV takes care of it.
I did time it with the distributor loose, that's how I got it from way retarded to slightly retarded. also fount a how to for the IACV. i'll reset the system and get on to a manual this weekend to check cam timing.
