Max fuel screw question?

[Rabbit TD]

Does the max fuel screw control the amount of fuel delivered just at wide open throttle or the whole way throughout the rpm range on a 1.6 T/D pump and also the N/A pump and how sensitive is it as far as adjusting?

[rallydiesel]

It adjusts the entire fuel curve, from idle to wot. It is very, very sensitive. Increasing the fueling a quarter turn too far will result in a pseudo runaway situation.
