I usually only soak mine if they've been sitting up for a while and are gummed up. I take the jets out, spray through them with some good carb cleaner that evaporates quick, then blow them out with a compressor. Get some pipe cleaners and run one through wherever you can other than the jets themselves. Spray carb cleaner through everywhere. Then take a q-tip in a drill and polish the seat for the float needle. And never get any kind of solvent on rubber or plastic parts.
