Fine Tuning
A slight correction of the setting of the
high speed screw (H) may be necessary
if engine power is not satisfactory when
operating at high altitude or at sea level
or after changing the tool.
Rule of thumb
:
Turn high speed screw (H) about
a quarter turn for every 1000m
(3300 ft) change in altitude.
:
Carry out standard setting.
:
Warm up engine for about 3
minutes.
At high altitude
:
Turn high speed screw (H) clock-
wise (leaner) no further than stop
until there is no noticeable increase
in engine speed.
At sea level
:
Turn high speed screw (H) counter-
clockwise (richer) no further than
stop until there is no noticeable
increase in engine speed.
It is possible that maximum engine
speed may be reached with the
standard setting in each case.
Adjusting Idle Speed
It is usually necessary to change the
setting of the idle speed screw (LA)
after every correction to the low speed
screw (L).
:
Warm up the engine for about
3 minutes.
Engine stops while idling
:
Turn idle speed screw (LA) slowly
clockwise until the engine runs
smoothly – the tool must not rotate.
