Adjusting idle speed
:
Carry out standard setting.
:
Start the engine and allow it to warm
up.
Engine stops while idling:
:
Turn the idle speed screw
(LD)
slowly clockwise until the engine
runs smoothly - the sweeper drums
must not rotate.
Sweeper drums rotate when engine
is idling:
:
Turn the idle speed screw
(LD)
counterclockwise until the sweeper
drums stop rotating - then turn the
screw about another full turn in the
same direction from that position.
Erratic idling behavior,
poor acceleration:
:
Turn the idle speed screw
(LD)
slowly counterclockwise no more
than one half turn.
The carburetor comes from the factory
with a standard setting.
This setting provides an optimum fuel-air
mixture under most operating
conditions.
With this carburetor it is only possible to
adjust the engine idle speed within fine
limits.
Standard Setting
:
Mount the sweeper drum assembly
and make sure it is in good
condition.
:
Check spark arresting screen* and
clean or replace as necessary.
:
Check the air filter and replace if
necessary.
:
Turn high speed screw
(H)
counterclockwise
(max.
3
/
4
turn)
as
far as stop.
:
Carefully screw the low speed
screw
(L)
down onto its seat. Then
open it
one
turn counterclockwise.
:
Start the engine and allow it to warm
up as necessary.
:
Adjust idle speed with the idle speed
screw
(LA)
so that the sweeper
drum does not rotate.
Fine Tuning
A slight correction of the high speed
screw
(H)
may be necessary if engine
power is unsatisfactory when working at
high altitudes or at sea level.
