step c (4) above for procedure.) Check condition of
fuel control unit and pin (para 3-44).
(5) Reduce speed to 1200 rpm and check fuel
pressure on gage (A, fig. 3-162) at compensator
inlet. Fuel pressure should be 40-55 psi. Adjust
droop screw to obtain fuel flow per Table 3-7. (Refer
to c (5) and (6) above for procedure.)
(6) If fuel flow cannot be adjusted to these
limits, check engagement of compensator stop plate,
torque link stop and guide, and the angular position
of smoke limit torque cam. (Refer to c (6) above for
procedure. )
(7) Reduce speed to 700 rpm and check fuel
pressure on gage (A, fig. 3-162) at compensator
inlet. Fuel pressure should be 30-40 psi. With
operating lever in idle position, adjust low-idle
adjustment screw (fig. 3-173) to obtain fuel flow per
Table 3-7. (Refer to c (7) above for procedure. )
(8) Check 2800 rpm full-fuel flow. If fuel flow
does not fall within limits, repeat (2) through (7)
above.

speed reaches minimum, push drive motor stop
