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.

Hmmm, the ones i've used have all (okay all four different ones) cut the
motor whenever there is no flow. Pull the trigger, the motor starts up,
release the trigger, the motor stops.

I have a Karcher and the motor keeps running. OK, it is quite old -
cylinder rather than upright.
