Follow Engine Starting and start the engine. Let it
idle while you:
Carburetor
High speed fuel calibration is maintained by fixed
high speed jet in the carburetor. Fixed jets are not
adjustable.
Observe running quality. If poor, refer to Trouble
Check Chart or see your Dealer.
Observe water pump operation. Water must flow
from the water pump indicator in a steady stream. If
it doesn’t, shut off the engine and investigate. Refer
to Engine Overheating.
Low speed fuel calibration is set at the factory with
a range of adjustment provided. If your engine dis-
plays poor running quality at low speed or idle, ask
your Dealer to perform the necessary adjustments.
Stop the engine and check the fuel system for
leaks.
Idle Speed Adjustment
WARNING
If your engine displays poor running quality at idle,
ask your Dealer to perform the necessary adjust-
ments.
Failure to check for fuel leakage could allow
a leak to go undetected, resulting in fire or
explosion.
Steering Friction
The steering friction was set on your new motor be-
fore it left the factory. After the first 10 hours of ser-
vice, check to see that it is still correct; a slight drag
should be felt when turning the motor. If adjustment
is necessary, turn the adjustment screw:
ADJUSTMENTS
Tilt Friction
•
Clockwise to increase friction; or
Adjust only enough to control return of gearcase • Counterclockwise to decrease friction.
from tilt to normal operation position.
IMPORTANT: DO NOT overtighten. Doing so in-
creases the pressure required to tilt the motor when
an obstruction is hit. Failure of the motor to tilt upon
impact can result in serious damage.
WARNING
DO NOT overtighten for “hands-off” steer-
ing. Reduced steering control could result.
