When furnace cycles on the humidifier overflow spout has a tremendous flow of water that pours all over basement floor. Is there a valve problem ? I can connect a drain tube from this overflow spout to the basement floor drain but, I've never noticed this great amount of water pouring out of the overflow in previous winter seasons

If the water stops when the heater is not running then the humidifier is working fine. I know it seems like alot of water but that's how it's designed.
It is not designed that way. There is a tiny orifice that slips into the inlet water hose connection. It essentially cuts the flow down to just a tiny amount of inflow. Enough that when the furnace cycles on, there should be a small amount of overflow down the tube (this keeps the water fresh), but not "gush". At some point that orifice fell out, or was never installed. This will allow toomuch water. Install the orifice. Also, when the furnace cycles on, adjust the valve that controls the water inflow to see a small overflow when running. Finally, if you have hard water, the buildup in the orifice can lead to the water being blocked. This needs to be soaked in vinegar monthly.
