John,
great job sticking to it and for seeing it through.

Now are you able to cruise the car below say 1,800 rpms without issue?
Duane,

In 4th gear it actually pulled 1400rpms without complaint.

I was surprised how little idle mixture screw adjustment was needed after drilling the IFRs. About 1/4 turn from the existing setting.
