CAUTION:
• Donot remove sealingcapsunless absolutely necessary.
• Never disturb full-load adjusting screwbecause thisalters
the mixture ratioandmay result inserious engineprob-
lems.
• Donot adjust maximum speedadjusting screwtoapoint
exceeding specifications, becauseexceeding themaximum
speed maycause engine damage.
• When attaching tachometer pickup,remove fueltUbe
clamps. (Refertotachometer instructions.)
Idle speed adjustment •

• Refer toMA section.

Idle speed:

SEF156R Maximum speedadjustment

1. Start engine andwarm itup until coolant temperature indi-
cator points tomiddle ofgauge.
2. Connect tachometer pickuptoNO.1 fuelinjection tube.
• Refer tothe instructions ontachometer.
3. Depress accelerator pedalfullyunder no-load andread the
tachometer indication.

Maximum enginespeed(Under no-load):
5,400 rpm

If
indication islower thanspecified maximum enginespeed,
adjust usingmaximum speedadjusting screw.
5. After adjustment, tightenlocknutsecurely andplug itwith
a sealing cap.

1. Warm upengine tonormal operating temperature.
2. Attach tachometer andadjust touchspeed usingadjusting
screw.
