If the idle drops when you spray around the throttle body then you
probably have a vacuum leak. Have you checked the condition of the
short, but fat rubber lines that run from the throttle body to the
intake runners? These are pretty critical. I put hose clamps on mine
just to ensure they were tight.
I would also check the cold start valve. If it is leaking that could
cause you to flood out.
I also agree that you should do all the other things that have been
suggested.

Check your timing. It becomes very critical on the air cooled in our
colorado hills. Especially above about 6500 feet. Learned that the
hard
way.
One of the reasons I now have a subie in my 82 westy. I actually cured
most
of my mountain woes by changing to a pertronix ignition when it was
still
air cooled.
In conjunction with the timing check the vacuum line from the manifold
to
the distributor. Replace the two rubber pieces on the ends of the line.
