Genset carb upkeep:  drain it and/or exercise it? Both?

The point of running a generator under load every month, according to Onan anyway, is to produce heat in the windings and help dry out moisture. It has nothing to do with a carburetor getting gummed up because Onan recommends the procedure for propane powered generators.
I have no idea if Honda recommends this same procedure for the same reasons. I have no idea if, as Matt suggests, this procedure isn't necessary anymore. I know it was in the manual for my 2003 Onan RV generator.
