Karl:

I have an '81 (non-California) air-cooled.  When it doesn't start right up
when warm, it is because it is flooding.  So I start with the pedal to the
floor to give it max air.  But if it doesn't start right away, it is
flooded.  I have a switch to turn off the fuel pump, so I crank with the
pump off for a couple of seconds until it starts to catch, turn the pump
back on and off I go.  In mine, it starts cold and starts hot, but sometimes
doesn't start "warm"--when it has been cooling down for ~30 minutes or so.

So besides checking/replacing the temp sensor on the head, I'd figure out
whether it is flooded or not when it doesn't start and go from there.
