Solution
• Check the spark. Remove the motor cover. Remove the spark plug from
the cylinder. Connect the spark plug cable and set it on top of the motor
cylinder with its metal part touching the cylinder. Pull the starter and watch
the spark in the spark plug electrode. If there is no spark, repeat the test
with a new spark plug.
• Press the starter choke until the fuel is visible in the choke. If no fuel is
showing it means that the fuel supply primary system is blocked. Contact
an Authorized Service Center. If the starter choke
fills with fuel, it means the motor is choked.
• With the switch off, remove the spark plug. Move the choke lever
downwards and pull the starter handle 15 to 20 times to eliminate the fuel
excess in the motor. Clean the spark plug and reinstall. Follow the
normal starting procedure (consult page 8). If the motor does not start,
move the choke lever downwards and repeat the starting procedure. If the
motor is still not running, repeat the procedure but this time using a new
spark plug.
