One needs the following measurement capability to proper determine what is going on.
1. A gauge to measure the "control line" pressure in the gas line between the fuel distributor and and the warm up regulator (J. C. Whitney). As the car warms up the pressure is coompared to the warm up chart of the warm up regulator for your year to comfirm function.
2. That the CIS control system is locking the fuel enrichment at 50% duty cycle with a measurement using a dwell meter or duty cycle digital meter.
3. Fuel filter is clean with no pressure drop
4. Thermo time switch is correctly requesting gas enrichment via cold start injector.
5. throttle plate area and idle bypass channel is clean and set properly.
