Lean condition under light acceleration

Mattax said
It's too lean at "cruise" when the engine surges (revs and dies) driving steady at 60 mph or higher.
Nothing magic about 60 mph on a flat road, its just a ballpark where the main system takes over and is providing most of the fuel under a steady condition.

I wasn't really clear about this in my original post. I am on the edge of that surge with the current setup. It's getting just enough fuel that it's not completely falling on its face, but it wants to.
