4. Repeat Step 2 and Step 3 until maximum idle
speed from adjusting idle mixture screw is the
same as the specified idle speed.
5. Turn idle mixture screw out until engine speed
begins to decrease, then turn idle mixture screw
in 1/4 turn.
6. Check the idle control adjustment as follows:
a. Adjust idle speed and mixture as described
above.
b. Adjust idle control screw until there is 0.10
to 0.20 mm (0.004 to 0.008 in.) clearance
between screw and rod of actuator.
c. Disconnect vacuum hose from actuator.
Check engine speed. If the engine speed is
less than 1400 rpm, no adjustment is neces-
sary. If the engine speed is higher than 1400
rpm, adjust screw until engine speed is 1300
to 1400 rpm.

when accelerator pedal or MONOTROL pedal
reaches floor plate. If necessary, adjust throttle
cable at bracket on engine. Loosen lock nuts and
move cable as necessary. Check that maximum
engine speed is within specifications shown in
the Maintenance Schedule.
