  • Page 43: Air Filter

    AIR FILTER A dirty air filter hinders the passage of air, reduces engine power and increases fuel consumption. For these reasons it is essen- tial to clean the air filter on a regular ba- sis. Follow these steps to gain access to the air filter.

  • Page 44: Spark Plug

    SPARK PLUG Keeping the spark plug in good condition makes for reduced consumption and opti- mum engine performance. It is advisable to remove the spark plug when the engine is hot (and naturally off) because the carbon formation and the colour of the insulator provide important information on carburetion, lubrication, and the general condition of the engine.
  • Page 45 CARBURETTOR - ADJUSTING THE IDLE SPEED Engine starting is strongly affected by the idle speed adjustment. In other words, an engine whose slow running is properly adjusted is easier to start than an engine with an unsuitably tuned up engine. The idle speed is adjusted by means of adjusting wheel and mixture adjusting...
  • Page 46 NOTE Failure to successfully complete the above procedure can be the result of an improp- erly sized idling jet. a) If the mixture adjusting screw is turned until it stops and no changes in the idle speed are observed, a smaller idling jet is required. b) If the engine stalls when the adjusting screw is still two turns open, a larger idling jet is needed.
  • Page 47 CHECKING THE FLOAT LEVEL (float height) Remove the carburettor and the float cham- ber. Tilt the carburettor so that the float touches the float needle valve without press- ing it too hard. In this position the float edge should be parallel with the float chamber sealing sur- face (see figure).

  • Page 48: Coolant

    DRAINING THE CARBURETTOR FLOAT CHAMBER The carburettor float chamber can be drained by following the procedure de- scribed below while the engine is cold. Close the fuel cock and place tube in a container to gather the fuel that flows out. Open drain screw and drain the fuel.
