Measure and set float height with final wet-test.

Set pilot-screws for best-idle with warmed up engine. That's setting that gives highest idle with prompt & crisp throttle response.
The carb saga is now complete

I synchronized the carb today and set the pilot mixture screws. I had to actually screw the pilot screws back in by about half a turn. They are at around 2 turns. The rpms now settle straight into the idle without hanging or dipping after the throttle is released.
