Carb Cleaning

I have some carbs that have been left a long time and have this dark brown stuff, which is a hard varnish like gunge in them. What is the best way of getting rid of the stuff. Is is in the float chambers, on the floats, in jets, in the carb throats etc.
I was going to try ultrasonic cleaning in acetone, but acetone does not seem to shift the stuff.

I now do the outsides and the float bowls, floats etc with walnut shells in my blasting cabinet...doesn't do shit for the passages...but cleans the outside of the carb great and often brings back that faint facotry rainbow anodizing.

How much does an ultrasonic cleaner large enough to fit a carb cost?
