They are not speaking of that.
Way down on the Fuel Injection Pump is the Throttle Arm. When you step on the Accelerator Pedal the Throttle Arm on the Fuel Injection Pump has to go all the way foward to the Stop Screw with no space between the Lever and the Stop Screw.
If the Arm does not reach that stop your Engine will not reach higher rpms.
