The engine is recovering momentarily from excessive pump shot volume.

The entire fuel curve from the main circuit is a tad rich in the middle.

He could leave the 40mm chokes in, run a 35 bypass, drop the main to 160 to start, and possibly drop the air corrector.

Myself, I'd drop the main to 150 and the air to 150 and see where the AFRs go, number drill up from there, then buy the right jets.
