Step 2
• Warm up the engine as follows:
Summer: approx. 5 min at idle r/min
Winter: approx. 8 min at idle r/min
• Water temperature should be more than 80 °C (176 °F) and
then wait 30 second.
• Then ISC valve automatically is set at throttle body synchroni-
zation position.
• Check for difference of vacuum between #1 and #2.
• Adjust the throttle valve synchronization and idling speed at
900 r/min by turning the air screw it necessary.
"
NOTE:
Always set the engine rpm at 900 r/min.
• If the adjustment is not yet correct, remove each air screw
and clean them with a spray-type carburetor cleaner and blow
dry with a compressed air.
• Also, clean the air screw passageways.
NOTE:
* Slowly turn the air screw in clockwise and count the number of
turns until the screw is lightly seated.
* Make a note of how many turns were made so the screw can
be reset correctly after cleaning.
Step 3
Repeat the procedures of Step 2.
