11. Pump the priming pump by hand a few times,
or energize the electric fuel pump if an electric
fuel is being used.
12. Use a clean towel to remove the fuel from the
top end of the delivery valve holder.
13. Slowly turn the engine in the normal direction
of rotation until you see the fuel rise in the end
of the delivery valve holder. Stop as soon as
you see the fuel rise.
14. Check position of the timing marks.
a. On the SB-210 the 10 degree BTDC
timing mark on the flywheel should be
aligned with the index mark on the side of
the timing mark access hole.
b. On the SB-310 the index mark should
align with the midpoint between the two
timing marks on the flywheel.
15. Repeat steps 10 through 14 to recheck the
timing.
16. If the timing is off by more than 1 degree (0.1
in. [2.5 mm]), loosen the mounting nuts on the
studs that fasten the injection pump to the
engine and rotate the injection pump to change
the timing.
