[DML] Tuning Idle Speed Circuit. (was: Re: idle problem)

["Adam 16683" <acprice1@xxxx>]

I am getting opposite opinions on which direction the delay valve is 
supposed to face. Harold, are you sure that the "dist" side goes 
toward the vacuum supply/tee fitting?

If anyone going to SEDOC wants, let me know and I'll bring with.

My CPR is totally different, but appears from vacuum diagram in Tech
Manual that "carb" nipple points towards Tee and "dist" nipple goes to
CPR.

Ford uses these things in horrifically complicated spark advance
setup. When they switched to 4350 carburetor, moved spark advance to a
full time vacuum port. Then had to route through delay valves and
ported vacuum switches just to make engine run. Stupid.
