Dwell / Duty Cycle Q.

[camron at worldaccessnet.com (Camron D. Crouse)]

Forgot to add:  Checking the duty cycle of the *Idle Stabilizer 
Valve*... just to clarify.

New info:  checked with hoses in place, the lowest value I could obtain 
(via adjustment of the idle air bypass screw only, leaving the A/F screw 
  in the fuel dist. alone) was 66%, Bentley target is 26-30%. Red probe 
on grey/white wire, black to ground.  I actually turned the idle air 
bypass screw quite a few turns, and quite easily with my bare hands... 
must need a new o-ring there? It is currently at full clockwise.

Do I need to go back and readjust the the A/F screw on the fuel dist, 
then check duty cycle again? Are these two adjustments interactive?  And 
if I adjust the ignition distributor timing, do I start over?

Thanks!
