Here are the two non-pristine areas.
The first is a hole that by all appearances got stripped out by a PO, then re-tapped off center. It could be run as-is, or if it bothers you it could be filled and drilled/tapped back on-center.

Here is the weld repair, at the front edge of the center carb base, just above the part number.
