Puzzle Corner
As we're in the mood for clever stuff ...
Every time I make a static timing measurement, the dynamic timing advances slightly! Why?:shock:
My pump is more advanced dynamically than most, because I've discovered something is missing from my pump. What?

hmmm, every time he measures the static timing,
That's with a dial gauge right?
the dynamic timing advances slightly.
hmmmmm???
A missing shim could advance timing dynamically

Yo ho h'mm.
Only 2 answers in 30 odd peeks
No-one yet with answer I seeks
This might help; A rule of thumb;
Never had the pump completely undone.

ARRRG!!! This is killin' me!
All I can think of is the timing advance spring is missing but that better not be, it would full advance all the time and wouldn't sound too good .
I probly won't sleep tonight.

There's a clue in my recent rants;rabbit_man wrote:-45F this morning, doesn't sound like G W to me. I wish I had a bearskin.
More hints???
All I have to say is; I was torquing about 'small potatoes'

Whilst I'm pleased with the few who've had a stab at my puzzle, the lack of other braincells is disappointing. Perhaps its the festive spirit.
I'll leave it a few more days before I give the answer.
To recap:
After I make each static timing measurement, my dynamic timing will advance slightly.
My pump is advanced dynamically more than most because I have discovered something missing from my pump.
I have not accessed internals as such.
You will all experience the same thing, if you do not take a simple precaution.
It is not detrimental to the car and may imperceptably [sp] improve things at higher speed.

You are saying that you are only making a timing "measurement"
not actually making an adjustment?

OK, let's think about this a little. When the injection pressure rises to the point where the injector "pops off" the fuel is injected into the cylinder. So for the dynamic timing of the pump to advance, the injection pressure would have to reach that point sooner in the cycle, therefore popping off the injector sooner.
If the washer under the timing access bolt on the back of the pump were missing, the volume of the chamber where the fuel is compressed by the piston would be reduced slightly. The injector pop-off pressure would be reached earlier in the piston's stroke, therefore advancing the dynamic timing slightly.
