STARTED, FINALLY!!!      

After putting this off for several weeks, several months after it last ran, I've finally got her going.  

Looks like rebuilding the carbs did the trick.  Lack of fuel was caused by the tank petcock being OFF.  Hot tip: don't attempt to reassembly carbs for the first time at night in the dark!

Big thanks to all of you for your continued help on this.  I've got a couple of remaining questions now:

- How do I adjust the idle, and what do I adjust it to?
- The choke lever is now stiff, and isn't easily pulled to full, but appears to be attached to the carburetor correctly.  Any thoughts on that?  Need some lubrication or something?
- I'm having a hell of a time securing the hose from the left carb to the back of the petcock cause I just can't get my hands in there.  Any tricks to that?

Thanks again, --Jon

Makes sense.  Been there, done that!

Turn the Idle Adjusment Screw.  Counter-clockwise (as imagined from above) to increase the idle, the other way to decrease.  The idle should be set to 1200 RPM (when the engine is warm).

Lubrication is the best guess.  The spring at the end of the cable isn't strong enough to cause problems, and the only other choice is a "sticky" pair of plungers in the fuel enrichening circuit.  (The 2 "plungers" are the items that the choke cable actually causes to move, down near the lower end.)

Can't think of any.  Just try, try again...!
