Unless Honda has changed to a bad idea, that carburetor is designed to be drained. How is that for an answer. If you plan to leave it alone for a long time (more than a couple of months) or just don't know when you might want it again. Get some "Fogging Oil" or Marvel oil. Get it warn and turn the fuel off. As it starts to sputter, fog the engine until it is stopped. Now, turn the crank until you feel compression. This means both valves are closed (and the points as well if it has). Now drain the carburetor and put the machine someplace safe.
Apart from the fogging, this is what it used to say in all the Honda manuals and there are reasons for all of it.
The old thing about running the electric end at load to warm the windings is left over from WWII. Everybody has used much better varnish on the windings for the last 60~70 years.
