Does anyone have any thoughts on this Carb they would like to share?

I don't know about that specific carb so don't know how it is jetted.  But the AFB's are easy to work on.  Frequently you can change the metering rods to get it dialed in, and that is done by loosening two screw, swiveling a flap out of the way, and removing the rod.

That carb is basically the Edelbrock Perforer carb and they have a guide on how to tune it here: https://www.edelbrock.com/media/wysiwyg/documents/carb-owners-manual.pdf.
