d) Setting the Idling Mixture Speed (S)
• Turnthesettingscrewforidlingspeed(S)clockwisetotherighttoincreasetheidlingspeed.
• Turningthesettingscrewcounter-clockwisetotheleftdecreasestheidlingspeed.
Set the idling speed with the engine still warm from operation so that the engine still runs securely. Avoid too-high
idling speed because this will cause the clutch to drag continually and speeds up wear.
e) Recovering the Factory Settings
If the screws are turned in too tightly, the carburettor or screws will be damaged! Loss of guarantee/warran-
ty! Do not use any force when turning the screws!
