TO ADJUST CARBURETOR
The carburetor has been present at the

or load. If the carburetor does need
adjustment, proceed as follows:
In general, turning the adjusting needles
In (clockwise) decreases the supply of
fuel to the engine giving a leaner fuel/air
mixture. Turning the adjusting needles oul
(counterclockwise) increases the supply
of fuel to the engine giving a richer fuel/
air mixture.
IMPORTANT: Damage to the needles
and the seats in carburetor may result if
screw is turned in too tight,
PRELIMINARY SETTING -

the throttle control cable is adjusted
properly (see "TO ADJUST

2. With engine off turn idle fuel adjusting
needle In (clockwise) closing it finger
tight and then tum out (counterclock-
wise) 1 tum.
FINAL SETTING -
1. Start engine and allow to warm for five
minutes. Make final adjustments with
engine running and shift/motion
control lever in neutral (N) position.
