cold start 99 GLE

My 1977 99 GLE, which is in great shape, runs very low on idle after the start, it hardly runs. Slowly the idle goes up to about 1350 RPM when it's really warm. CO is fine (2,5%) when warm, not that much higher when it is cold 4-5%?). The warm up regulator has been renewed (4000 miles ago), but it might not be the right Bosch number. I know the fuel distributer has been changed once (by a 1985 distributor) My questions:
1. What could be the cause of the problem?
2. What Bosch number should the warm-up regulator have, or doesn't it matter?
3.Does it matter which fuel distributor is being used?
4. Sometimes the fuel pump does not run when turning the ignition key to the right, sometimes is does. What can be the cause, and is this bad?
5. What should be the difference at idle between position D and P, and how can this gap made smaller?
Thanks for answering!
Thom
