[Vwdiesel] max fuel adjustment

[Will Taygan]

Ummmm...

Is this right?

Top of pump (screws connected to accelerator) controls the amount of
fuel injected, thereby controlling idle and max rpm.

Side of pump controls max fuel given at a particular degree (of the top of pump accelerator control), in
essence giving more fuel for the idle, more fuel for the mid range and more fuel for max at a given rpm,
(raising the scale).

I'm going pick up a copy of the bosch ve yellow book to see if I can internalize this.
