a. Start the engine, warm it up for several min-
utes, and then let it run at the specified en-
gine idling speed.
b. Using the throttle body that has the bypass air
screw “1” with a white paint mark as the stan-
dard, adjust the other throttle body by turning
its bypass air screw in or out.
NOTICE
ECA23P1079
Do not turn the bypass air screw of the throt-
tle body that is the standard.
Otherwise, the engine may run roughly at
idle and the throttle bodies may not operate
properly.
TIP
• Turn the cylinder #1 air screw or cylinder #2 air
screw using the carburetor angle driver.
• After each step, rev the engine two or three
times, each time for less than a second, and
check the synchronization again.
• If a bypass air screw was removed, turn the
screw in fully and be sure to synchronize the
throttle bodies.
• If the throttle body synchronization can not be
adjusted using the bypass air screw, clean or
replace the throttle bodies.
• The difference in vacuum pressure between
the throttle bodies should not exceed 1.33 kPa
(10 mmHg).
