Can't stop the surging

The OEM Briggs carb to block gasket is like 1/8" thick or more.

If you buy a Chinese Amazon or Ebay carb, they give you a much thinner gasket.

Ah, thanks for that wisdom - yes, it came in the same box with the chi-con carb.

Again the Briggs gasket is like twice as thick and the Chinese one. Obviously use the Briggs part.
