Sorry for all the dumb questions, I’m still new to the hobby and what I lack in mechanical experience I make up for in enthusiasm!!’

Regarding settings of the Rpms on a 289 auto with an edelbrock 1406 2BB carb, I know there is a screw on the left side (as you stand in front of the car) on the carb to adjust the rpm when the car is placed in drive and another screw underneath that one to set high rpm when the choke is on, but how do you set the rpms when the car is in park and not cold or under load ??

Btw, thanks for all the assistance and I sincerely hope my dumb questions don’t get on anybody’s nerves !!

The same screw for adjusting the idle in drive is used...IIRR, for the automatic, the idle speed in park should be about 800 rpm.

You just set the idle speed and fuel mixture while in park (setting hand brake and blocking the tires are good ideas). Don't try to adjust engine speed while it's in gear (unless it's up on jack stands). That's an accident getting ready to happen.
