the CDR is the Crankcase Depression Regulator.
"The CDR valve is responsible for controlling the pressure/vacuum in the engine crankcase, and seperating the oil mist from the air and returning the oil to the crankcase."

Pull it off, Soak it in gas, DO NOT BLOW it out with air! That will rupture the diaphram.
If you get chunks of rubber out of it, toss and replace.

Take off the filter housing, look right behind the intake opening. It looks like a Little can about four inches across and three inches thick.
