ADJUSTING THE MECHANICAL CONTROLS OF THE DELPHI INJECTION PUMP
Engine: WJY (continued)
Adjusting the antistall (residual output).
Insert a 3 mmthick shim (10)between the throttle lever (6)and the antistall screw (7).
Push the stop lever (8).
Insert a 3 mmdiameter peg (9)in the lever (2).
Adjust the engine speed to 1500 rpm ± 100using the stop screw (7).
Remove the shim (10)and the peg (9).
Adjusting the idle speed.
Adjust the speed using the idle adjustment screw (11).
Idling speed:825 ± 25 rpm.
Checking the engine deceleration.
Move the throttle lever (6)to obtain an engine speed of 3000 rpm.
Release the throttle lever (6).
The deceleration should be between 2.5and 3.5seconds.
The drop should be approximately 50 rpmin relation to the idle speed.
Deceleration too fast, (the engine has a tendency to stall)slacken the screw (7)by a quarter turn.
Deceleration too slow, (engine speed is greater than the idle speed)tighten screw (7)by a quarter turn.
NOTE:In each case, check the idle speed for any necessary adjustments.
