What usually works for me to clean out carbs, petcocks and various other parts that have crud on them is to put them in an ultrasonic cleaner. I normally use 'simple green' as the cleaning solution and sometimes carb cleaner. Usually there is no need to take the item being cleaned apart, although sometimes that is necessary. After 30 minutes or so, take the part out, dump the cleaning solution (you can often reuse it, so, put it in a container for later), fill the ultrasonic cleaner with fresh water, run it again, take the part out, dry it with compressed air and you will probably be good to go.
