At what rate is it surging - like several times per second, once every few
seconds, etc.?


equal pressure / no pressure ... about 2 sec on 2 off or maybe a little
less.


During this pressure fluctuation, is the motor running all the time - or
does it keep starting and stopping?


Motor running contiuously


When you fist turn it on with the outlet closed (i.e. trigger on lance not
operated) does get up to pressure and then cut the motor, like it's
supposed to?


Never done that ... iut would just run up to load and motor stay at load,
never cut/in out. (Hobby 88 is model)
sound wouldof course change, but does not stop running.
