Since the mixture control solenoid valve is
factory adjusted, it must not be overhauled
or its jets must not be removed.
l
Since the mixture adjust screw is also factory
adjusted, it must not be adjusted at the field
except the following.
a. When the carburetor assembly has been
replaced.
b. When the carburetor has been overhauled.
c. When the idle mixture adjustment is
necessary due to the emission test failures.
To adjust the mixture adjust screw in one of
the above conditions, drive out the pin in
front of the screw. After the adjustment, a
new pin should be installed.

[Fuel cut system]
The primary slow system incorporates the fuel
cut system with the fuel cut solenoid valve
which is operated by the ignition switch and the
ECM. When the ignition switch is at “OFF”
position or during deceleration, the fuel cut
solenoid valve stops the fuel flow into the idle
down channel by closing the fuel passage. Thus
the fuel cut system helps to prevent the
ing and improve the emission performance and
fuel economy. For details, refer to SECTION 5
“EMISSION CONTROL SYSTEM”.
