  Not really.  Although the max fuel screw does in reality just 'lift the 
lid' for the maximum fuel, it's more of a sliding scale with the bottom 
end still accessable by adjusting the idle.  If you turned it 1/2 turn 
and didn't change the idle, it sounds like you turned the wrong 
thing.  Turning it 1/2 turn should not only make the idle really slow, 
it should really lower your maximum power.  You'll have less fuel 
under non boost conditions as well (if you turn it down) making boost 
lag longer.
  Like Andrew said, unless the injectors are known good to great, then 
do them before you mess with anything else.

  The dot is irrelevant other than your own personal reference AFIK.  I've 
never really checked but I highly doubt that it's oriented the same on 
every cone/diaphragm assembly.  It's simply a washer with a dot which 
makes it easier to have a location to put things back.  DO NOT undo the 
nut, simply because there's no need.  Just pull the diaphragm out, look 
down the hole to see where the pin is (I never remember which side it's 
on) then look at your cone for the mark of where the pin's been sliding. 
That will let you position it back where it was.
  With all else well, smoking only under full to nearly full boost, full-ish 
throttle, etc would simply be the cone orientation or the "smoke screw."
That would be the adjustment on top of the aneroid.  Down would limit 
the travel and cut down the maximum, under boost, fueling.  If it 
smokes too much under most boost conditions then rotate the cone 
so that it's farther away from the pin, on its eccentric.
