[Gemni911]

I'm having a similiar problem and am troubleshooting my 76 911S. Starts right away but will not idle when cold. Idles fine warm. Will die without keeping the throttle open to 2 or 3 K for at least 5+ minutes. Fresh rebuild with a rebuilt fuel distributor, new thermo switch, rebuilt tank, filters, etc... Not sure what fully open AAR looks like. (shows a cresent with the notch almost centered - seems to allow plenty of airflow); closes in less than 4 minutes. Fuel pressure readings were correct at all three stages. New engine is not running smooth although timing is correct. I have not spent too much time looking at this stuff yet but am just starting to and so will go over the basics including checking for vacum leaks.
