5. Raise the fuel container above the level of the
injector; then rotate engine counterclockwise until
reference mark (D) is to the left of the 13° BTDC
mark (B) or until fuel is observed flowing from the
bleed hose.

6. Rotate the engine clockwise and stop immediately
when the fuel stops flowing. This indicates the
beginning of injection.
DE446
7. Observe the alignment of reference mark (D) and
the 13° BTDC mark (B).
DE561A
NOTE: If marks are aligned, timing is correct
(proceed to step 9). If marks are not aligned, the
injector timing must be adjusted. Adjust injector
timing using the following procedure.
8. Observe the position of the reference mark (D) and
the 13° BTDC mark (B) and note early or late
injector timing.
NOTE: If the reference mark (D) is left of the 13°
BTDC mark (B), injector timing is early. If it is to the
right, injector timing is late.
A. Rotate the engine to perfectly align reference
mark (D) and 13° BTDC mark (B); then loosen
the jam nut on the fuel injector timing adjust-
ment screw. For late timing, proceed to step B.
For early timing, proceed to step C.
