I'm going to take a s.w.a.g. that a day on the dyno spent on tuning ONE carb is probably enough to get a basic carb sorted out, if the original tune isn't close.
And sometimes....... Even after a full day...... You might still not get there if what it really needs from the start is a booster change, and you don't have the pieces on hand to perform that operation.
