IT'S ALIVE!
Got the bike running. Put in fresh gas and installed the fully-charged battery. Something odd - the starter will still crank w/ the starter switch in the 'OFF' position. I tried to start it with the switch in the 'OFF' position and the fuel valve closed.
Opened the fuel valve, turned the ignition switch to the 'ON' position, and opened the choke.
*sputter* *sputter* VROOOM!!!!!!!
It was only runnig with the choke and/or throttle open. Close one or both and the thing eventually slowed down and died. I found the idle speed screw and turned it until the bike idled at 1000 rpm. Viola! I bought some 1/4" fuel line from the hardware store and replaced some of the more corroded fuel lines. I bought five feet of tubing. I'm hoping that's enough to eventually replace all of it.
The next step is to rebuild this crusty thing so that I actually have brakes to stop with. Unfortunately, that window isn't replaceable so I have to buy an entirely new body, but it's only $30 with shipping. Honda used the same master cylinder for nearly a decade on dozens of models. After that, it's just a matter of dropping in the new piston and bleeeding the front brakes.
Still have to get the bike titled, tagged, and registered. Yay, bureaucracy.
