John,

Send me an address offline, it is yours.

Using the screw...and I have it at its max mechanical limit...not enough.

I am running the ECU off of the tach output from MSD.	 I used the wiring
diagrams from MSD/HOLLEY, I am assuming this is the right way to do it.

I think this may have something to do with the problem.  I will do this an
report in.

<Smacks himself upside the head>  Of course! That makes perfect sense. I
like having positive control.  I know that the choke dashpot on the ECU
controls how long the fast idle is extended...and assume that it is temp
related. But positive control is well...more positive.

I know that, but I have not yet seen it in action.  I need to test the
solenoid and the ECU to see if I am getting any power to it.
Hofs, no thin skin here...I like to start with the basics and work my way
from there. Thanks for your thoughts.
