• Use a tachometer with graduations of 50
rpm or smaller that will accurately indicate

lightly and back it out to the specification
given. This is an initial setting prior to the final
pilot screw adjustment.
INITIAL OPENING: 3 turns out
CAUTION:
Damage to the pilot screw seat will occur
if the pilot screw is tightened against the
seat.
2. Warm up the engine to operating temperature.
Stop and go driving for 10 minutes is sufficient.
3. Attach a tachometer accord ing to its manufac-
turer's instructions.
4. Adjust the idle speed with the throttle stop
screw.
IDLE SPEED: 1,000 ± 100 rpm
5. Turn each pilot screw
1/2
turn out from the
initial setting.
6. If the engine speed increases by 50 rpm or
more, turn each pilot screw out by successive
1/2
turns until engine speed drops by 50 rpm or
less.
