Gas leaking from both carbs

[busmania]

Recently, I noticed after a drive where the engine gets all the way up to temp when I stop I can hear boiling in the carbs and gas leaking out of what appears to be the throttle plates. I know I need to check my fuel pump pressure, but could also be floats? is there a tutorial somewhere that shows how to adjust and floats?

These are two new (800 miles) stromberg 97’s.
