 AIR SCREW ADJUSTMENT                              Air Screw
 Turn the air screw clockwise until it seats
 lightly and back it to the specification given.
 Do not force the air screw against its
   seat to prevent damage.


 Start the engine and turn the air screw in or
 out slowly to obtain the highest engine
 speed.

                                                               Throttle Stop Screw



 Turn the throttle stop screw to obtain the
 specified idle speed.
 Idle Speed: 1800100 rpm
 Air Screw Opening: 2  1/2 turns




 Slightly increase the engine speed and make
 sure that the engine does not miss or run
 erratic.
 If the adjustment of the air screw within the
 range of 1/2 turn makes no difference to the
 engine performance, check other related
 items.
