Let me try one more time wording it differently.
In order to get the pump to pump the contacts have to close. This happens
when the diaphragm releases i.e. moves towards the contacts. The contacts
toggle is screwed onto the long threaded stud that comes back from the
diaphragm. This is a normal thread, so if you screw the toggle clockwise
when looking down on the contacts and the diaphragm is underneath them you
will screw the toggle closer to the diaphragm. This means that when the
diaphragm releases the toggle won't move as far and so the contacts are
*less* likely to close. The correct adjustnment is to screw the diaphragm
into the toggle until the toggle doesn't close the contacts, then unscrew it
untill they just flip over and close, then unscrew it a further 1/4 turn.
But the fixed contact has to be tensioned such that it presses down on its
mounting pedestal so that when the toggle flips over the moving contact hits
it.
