Remove the spark plug in this case. Carefully dry the spark plug with compressed air. Hold a cloth above the engine

cylinder and pull the cable pull starter several times to remove excessive fuel from the combustion chamber. Insert

the spark plug again and start again without choke. If the motor does not start up again after the tenth attempt, try

the process again with the choke set.

must careful changes be performed. Even slight turning of the adjusting screws will have large effects!
