additional things i have learned:
1. The LED at X92 is ON continously at KOEO, but turns off when engine is running. At that time, I pressed the push button for 2-4sec and got a (1) flash. I pressed the button one more time and I got a continous ON LED. At this time, I got to on/off ratio test mode at X11.
2. Still not happy with my duty cycle readings, i decided to measure voltage instead at pin2-3. Engine was about 80 degrees. At idle( about 750RPM) I got an oscillating voltage from 2-3 volts at 12.93V battery voltage. This calculated to about 76% - 84% duty cycle which I thought are rather high. I revved-up to 2500 and measured 4.8-6V. This calculates to about 53%-63% duty cycle. At this point, i am not really sure what to do. With hard cold start as my original problem, now I think I am seeing one more problem with the duty cycle which may need mixture adjustment.

your thoughts would be appreciated.
