Ok, here's what I know:

Ok, all done!

seriously tho:

On the electric choke element on the side of the carb is a small dot.  On
the carb there are 2 marks like this || that you put the dot betwixt.  This
is the starting point.  If you rotate the choke around back and forth, you'll
see where it just starts to move the butterfly.  I set mine so it just off
the contact a bit when cold.  An old bus guy I know taught me this, and it
seems to work, but maybe _I'm_ doing it wrong, too...
