Troubleshooting 

If the engine cannot be started, proceed as follows to find out the cause: 
 (1)

 

Check the level of fuel in the fuel tank to see if it is low. 

 (2)

 

Check the fuel supply system to see if the fuel is flowing into the carburetor from 
the fuel tank. 

 (3)

 

Loosen the drain screw of the carburetor to drain off fuel and then screw the drain 
screw back in place. 

 (4)

 

Push the kick starter lever with the foot several times. 

 (5)

 

Loosen the drain screw and then check if there is fuel inside the carburetor. 

 (6)

 

If  it  is  confirmed  that  fuel  has  reached  the  carburetor,  check  the  ignition  system 
next. 

 (7)

 

Remove the spark plug and connect it to the high-tension cord. 

 
Fasten  the  threaded  part  of  the  spark  plug  to  the  engine  housing,  turn  the  ignition 
switch  to  the  ON  position,  push  the  start  button  and  see  if  there  are  blue  sparks 
generated between the two electrodes. If no sparks appears, call your dealer and book it 
in for repair. 
 

CAUTION 

Do  not  allow  fuel  to  run  on  to  the  ground,  Collect  it  in  a  container.  Keep  fuel  away 
from  the  hot  engine  and  exhaust.  When  performing  this  test,  keep  away  from  fire  or 
other sources of heat.
