The four positions
of the Master Control lever
To start the engine, move the lever to
"Cold Start" position (1) -
do not use force.
If the Master Control lever is on
"Run" (3): Press down the throttle trigger
interlock - and move the Master Control
lever downward.
"Cold Start" position: Choke shutter is
closed - throttle trigger is in starting-
throttle position. A cold engine should be
started in this position.
As soon as engine begins to fire,
move the Master Control lever to
"Warm Start" position (2):
Move the Master Control lever one
notch upward.
"Warm Start" position:
Choke shutter is open -
throttle trigger is in starting-throttle
position.
If you leave the Master Control lever
in the "Cold Start" position,
the combustion chamber will flood
and stall the engine.
The Master Control lever must be in
"Warm Start" position (2) to start a warm
engine. Also select this position if engine
has been running but is still cold.
The Master Control lever should not be
forced to "Run" position (3) -
it will move to "Run" as soon as the
throttle trigger is activated.
In the "Warm Start" position, continue
cranking after engine begins to fire.
As soon as the engine runs,
immediately blip the throttle trigger
so that the Master Control lever moves to
"Run" - idling position -
normal operating position (3).
To shut down the engine:
Move the Master Control lever upward
to "STOP" position (4):
The stop contact should engage the
contact spring - this cuts off the ignition
system.
