SERVICE INSTRUCTIONS
To adjust the carburetor for engine idle, use the follow-
ing procedure:
1. Gently close the idle mixture needle valve by turn-
ing it
clockwise until it bottoms lightly.
IMPORTANT: The needle valve and carburetor
seat may be damaged by turning the adjustment
screw too tight.
Carburetor Adjustment
2. Preliminary Setting: Turn the idle mixture needle
valve out (counterclockwise) 2 turns from the
closed position. This
initial adjustment will allow
the engine to be started and warmed up prior to the
final adjustment.
3. Start the engine and allow it to warm up for approx-
imately five (5) minutes.
4. Move throttle to the IDLE position. Adjust idle
speed for 1300 RPM by adjusting the idle speed
screw. Check the idle speed using a tachometer.
5. With the engine idling, adjust the idle mixture by
turning the needle valve until the engine slows
(clockwise - lean mixture). Then turn the needle
valve out past the smooth operating point until the
engine slows again (counterclockwise - rich mix-
ture). Now turn the needle valve to the midpoint
between rich and lean mixture. Check engine ac-
celeration from the idle. If the engine will not ac-
celerate properly, readjust the idle mixture, usually
to a slightly richer mixture (open the valve).
6. Recheck idle speed after the final idle mixture ad-
justment.
Carburetor - Model MW
Carburetor adjustments are required to compensate for
differences in altitude, temperature, and fuel. Once the
carburetor has been set, no further adjustments should
be required. However, if the engine exhibits any of the
following symptoms, the carburetor adjustment should
be checked by an authorized Kawasaki engine dealer:
black, sooty exhaust smoke, lack of power, engine miss
or backfire, hard to start, rough running or idle.
Carburetor - Model MB
The Vanguard ohv twin cylinder engine carburetor fuel
mixture adjustment procedure is unique. Perform ad-
justments exactly in the sequence shown.
Initial Adjustment
1. Turn idle mixture screw clockwise until it just seats.
DO NOT FORCE.
2. Turn valve counterclockwise 1-1/4 turns.
This setting will permit engine to start. Final adjustment
will be made with engine running.
DANGER
The engine must be running to adjust
the carburetor for engine idle. To guard
against injury, keep hands, feet, face, and
other parts of body away from the muffler/
exhaust pipe, other hot parts of the engine,
and moving or rotating parts of the engine.

ernor has been factory set for maximum
safe engine operating speed.
