Hi Scott,
It may not be necessary to go into choke adjustment yet. The key is your
statement "fully applied". The starting procedure is to pull the choke
fully until the engine fires, then partially release it so that it isn't
so rich. The engine will still be on fast idle until you completely
release the choke but the mixture is only rich with the choke fully
pulled. You can gradually release it to progressively slow the idle.
There is a "fast idle" adjusting screw which sets engine speed with the
choke in the partially released position.
You can get a pretty good idea of how the carb works here:
