An old racer trick was to put fuel cell foam inside the carb bowl to dampen sloshing. Just had to make sure it never gets tangled up with the float. Doesn't work well with small bowls that are almost completely occupied by the float. Just a curiosity, probably won't work for you....
Check the float level, any other adjustments are a wasted effort until it's set right.
