The car, 1974, retains its original FI. Fires up no problem, but, until it warms up it almost dies as the rpm is almost zero, or, it almost dies until the temp bumps up.
When warm it is a nice 800/900 rpms and idles nicely.

I tried to do a search but it never works for me as the website is beyond my mortal understanding.

(IMG:style_emoticons/default/agree.gif) Most likely cause. Pull the vacuum line from it when cold to see if any air is being pulled through. Then it should close up after ~5 to 8 minutes. If it's not pulling air when the car is stone cold, then it's stuck a closed state, and that's your issue.
