OPERATING INSTRUCTIONS
Starting and Stopping
COLD STARTING PROCEDURE
The carburetor on this engine is equipped with a fuel primer and a choke
system. To start a “cold” engine properly, perform the following procedure:
1. Pump the primer bulb until fuel can be seen flowing through the fuel return
line to the fuel tank. (Flowing fuel should be almost clear, not foamy or full
of bubbles.)
2. Turn the choke lever to the Close position.
3. With the stop switch “ON”, and the throttle trigger positioned at Fast-idle
position, pull the starter grip.
After the engine is started, turn the choke lever to the Open position. Then
squeeze and release the throttle trigger to allow it to return to the idle posi-
tion.
If the engine stops running before you turn the choke lever to the open posi-
tion:
Go ahead and open the choke, pull the starter grip with the throttle trigger
positioned at Fast-idle position.
HOT RESTART
To start the engine that is already warmed up (hot restart), or if the ambient temperature exceeds
68°F(20°C):
1. Pump the primer bulb until fuel can be seen flowing through the fuel return line to the fuel tank. (Flowing
fuel should be almost clear, not foamy or full of bubbles.)
2. Turn the choke lever to the open position, and set the stop switch to the “ON” position.
3. Leave the throttle trigger in the idle position and pull the starter grip.
If the engine fails to start after you follow the above procedures, contact an authorized
INCOLFLEX
dealer.
TO STOP THE ENGINE:
1. Release the throttle trigger.
2. Slide the stop switch to “STOP” position.
CARBURETOR ADJUSTMENT
The carburetor has been carefully adjusted at the factory and should not
require any further adjustment. Only the idling speed can be adjusted by
turning the idle speed adjustment screw (see sketch). The correct speed is
2400 - 2800 RPM (or just below the clutch engagement speed ). Turning the
adjustment screw clockwise will increase the idle speed.
If further adjustment is necessary, please contact a local authorized
INCOLFLEX
INCOLFLEX
dealer.
