Adjustment
In generat, turning the adjusting needles (Fig_29) in (clock-
wise) decreases the supply of fuel to the carburetor_ This
gives a leaner fuel/air mixture,
Turning the adjusting
needles (Fig. 29)
out (counterclockwise)
increases the
supply of fuel to the carburetor.
This gives a richer fuel/air
mixture_ Setting the needles midway between the lean and
rich positions will usually give the best results,,

With the en_Tinestopped, turn the idle fuel adjust-
ing needle m (clockwise) until it bottoms lightly.,

adjusting needles are tapered to critical dimen-
sions_ Damage to the needles and the seats in
carburetorbody
will result ff the needles are forced
b
