mechanical cleaning of carbs with wires can ruin them.  It's quite possible
to enlarge them.  (not very likely with a copper wire, but you can scratch
them.) which will change how they behave.  I don't have any experience with
cleaning carbs with ultrasonic baths, but I've had lots of other delicate
bits done, and it works very, very well.
