Allen,

FYI, that is not an advance, but a RETARD. The more the little button is pushed in, the more the cam ring is the pump is retarded, to compensate for the earlier start of injection when you stomp on the footfeed, and pour the coals to it.

As the diesel pump pistons achieve full stroke under full fuel rate, injection starts earlier, since the pistons in the more completely filled bores contact the cam ring sooner, so this retarding of the cam ring is needed to back off the timing of the start of fuel injection to a safe point.
