    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 1 and mixture adjusting screw 2.
  • Page 54 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.

    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 4 in a container to gather the fuel that fl ows out. Open drain screw 5 and drain the fuel.
  • Page 56 DRIVE CHAIN MAINTENANCE The life of the drive chain largely depends on its maintenance. Chains without X- rings must be periodically cleaned in petroleum and then immersed in hot chain oil or treated with a chain spray. X-ring chains require very little maintenance. The best way to clean them is rinsing them generously with water.
