NOTE: When using non-ethanol
gasoline, the pilot screw on the car-
buretor should be turned fully clock-
wise to the stop. When using
gasoline containing ethanol, the
pilot screw should be turned fully
counterclockwise to the stop.
Throttle Stop Screw
This screw controls the seating position
of the throttle valve which in turn deter-
mines the proper idle speed. Rotate the
screw clockwise to increase engine idle
speed and counterclockwise to decrease
engine idle speed.
Checking/Adjusting
Throttle Lever (Tension)
NOTE: Ensure that the throttle
cable is properly seated in the throt-
tle control housing.
1. Verify when releasing the throttle
lever that the round switch in the
control housing is compressed. If the
switch is not compressed the engine
will shut down when the throttle
lever is released.
2. If the throttle cable needs to be
adjusted, locate the throttle cable in-
line adjuster next to the steering
post.

3. Tighten nut against the in-line
adjuster and cover the adjuster with
rubber boot.
In-Line Fuel Filter
Whenever
inspection is made on a fuel system
when there may be fuel leakage, there
should be no welding, smoking, open
flames, etc., in the area.
BRP recommends that the in-line fuel filter
be checked once a month. The filter is
located in the fuel hose between the gas
tank and fuel pump. The only cleaning
possible is to back-flush the filter using
clean gasoline. To check, clean, or replace
the filter, use the following procedure:
1. Using a suitable hose clamping pli-
ers, pinch off the fuel hose between
the gas tank and the filter.
2. Remove and discard the clamps;
then slowly remove the fuel hoses
from the fuel filter. Dispose of the
excess fuel from the filter properly.
3. Install the in-line fuel filter in the
fuel hose so the arrow on the filter
points toward the fuel pump. Make
sure the fuel hoses fit tightly on the
filter. If a fuel hose does not fit
tightly, cut 6 mm (1/4 in.) from the
end of the fuel hose; then install on
the filter. Install new clamps and
remove the clamping pliers.

The fuel hoses must fit tightly on the
fuel filter. If the fuel hose length
doesn't
replace the fuel hose. Also, after
installing the fuel hoses on the filter,
check to be sure that the fuel hoses
do not contact any hot or rotating
components.
