Checking installed positions of
levers:
- In the idle position the choke
shutter must be closed and the
throttle shutter at an angle of 37
degrees to the carburetor moun-
ting face.
- Open the choke shutter by slowly
turning the right-hand end of the
choke shaft. The throttle shutter
must jump to the closed position
just before the choke shutter is fully
open. This is accompanied by a
definite clicking sound.
Important: The choke shutter must be
held open for the next two operations.
- Fit lever "H" on the throttle shaft
and rotate it counterclockwise
against the pin on lever "A".
- Press lever "H" on to the throttle
shaft.
- Turn the idle speed screw "LA"
counterclockwise until the throttle
shaft is clear of the taper on the
idle speed screw.
- Open the choke shutter "I" and hold
it steady in that position.
- Swing lever "A" counterclockwise
as far as stop.
