My manual says to adjust the IAC cone so the tip of the cone is about 1.125" from the o'ring seal seat. This adjustment is done with the IAC removed after a normal engine shut down. The valve is spring loaded and can be adjusted in or out by twisting it on its threaded shaft. After exploring the area the cone valve extends into I realized there is a ton more room for the valve to extend into this area. It was in no danger of bottoming out, which is what the manual warns about with the 1.125" limit.

I can perform a cold start fine with the IAC removed and this area plugged up, so I figured the IAC wasn't limiting the airflow enough to give plenty of fuel upon cold startup. I adjusted it to about 1.20" and now I can start cold. I've waited to post to really try it out over a couple weeks and it starts on about the 3rd or 4th crank cold which I figure is about average. Car seems to idle normal.

P.S. During routine maintenance I checked the CV boots and at 90k miles they are fine, look almost untouched. How come I had to replace the boots on my wife's Honda at 90k miles ? I thought Japenese cars were so much better ?
