Couple things -

I don't think you could install them correctly with the carbs upside down. With the carbs right side up, you would want to put the spring on the screw first, then the washer, then the o-ring last before inserting it in the carb.

Like this - https://faq.ninja250.org/wiki/File:BC_cleaning_4.jpg

Is that how you did it?

Because you said the adjustments didn't seem to do much, I'd say there is an issue with that circuit. Either the passages are still partially plugged or the adjustment screws are assembled incorrectly.
