Do you understand the theory of operation of the injection pump? Timing should be correct when the line on the pump flange and the line on the engine adapter plate are lined up. This pump is variable beginning of injection and constat ending. At WOT at specified delivery Start of delivery is 30 degrees on the early engine and 28 degrees on the late. These numbers will only occur at WOT and decress as fuel delivery and metering valve move towards less fuel position.
