NOTICE
If the starter motor will not turn when the
start switch is pushed, stop pushing it im-
mediately in order to avoid placing extra
load on the starter motor, and start the en-
gine by using the kickstarter.
TIP
If the engine fails to start, push the engine stop
switch and give the kickstarter 10 to 20 slow
kicks at full throttle in order to clear the engine
of the rich air-fuel mixture retained in it.
4. When the engine starts running, warm this
up one or two minutes at a steady speed (of
3000 to 5000 r/min), and then return the
starter knob/idle screw to its original posi-
tion.
