3. Start the engine. When operating
temperature is r aed, unplug one spark
plug lead and adjust the throttle stop
screw for the other cylinder so that the
engine idles as slowly as possible. Then
turn the pilot screw in or out until the
engine runs smoothly. It should not be
necessary to vary the screw more than
one half turn in either direction from the
given setting.
4. Connect the spark plug lead and run
the engine a few moments to allow the
engine to clear out. Repeat Step 3 (above)
for the other cylinder.
5. Connect both plug leads again and
turn each throttle stop screwout by equal
amounts until the properidle is reached.
6. Check that the two carburetors are
synchronized by opening and closing the
throttle while watching the throttle stop
screws. Both screws must begin to move
at the same time when the throttle is
opened. If one begins to move before the
other, use the cable adjusters on the c
buretors so that the movement of the stop
screws is synchronized.
7. Snap the throttle open and closed
several times to make sure that synchro—
nization is maintained.
8. Adjust the throttle cable free—play
using the adjuster near the twist—grip so
that the throttle has 10—15° of free rota—
tion before the stop screws begin to
move.
