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.
