acceleration
(even though you have opened low
speed screw one quarter of a turn)
Idle setting is too lean.
: Turn the low speed adjusting screw
(L) counterclockwise until engine
runs and accelerates smoothly.
It is usually necessary to change the
setting of the idle speed adjusting screw
(LA) after every correction to the low
speed adjusting screw (L).

necessary if engine power is not
satisfactory when operating at high
altitude:
: Check the standard setting.

clockwise (leaner). On models with
