You should drain them any time you think your next ride might be several weeks in the future. Getting the gas out of the float bowls helps reduce or eliminate the possibility of your carb internals getting gummed up and needing to be cleaned.

Hold the float gently up to simulate a full float bowl and connect the gas line to the carb. Remember the gas is only going to push up the floats gently, by pushing too hard you will get it to shutoff even if it is worn out. If it leaks, it may just be the float needle is damaged.
