Carburetor
preheating
If outside temperatures
are
below +1000
(50°F), change
the
flow of intake air to
the carburetor to "winter
operation"
to avoid the carburetor
icing up. To do this,
use
the carbu-
retor screwdriver
to open the flap in the housing
just under
the spark plug.
This causes hot air
from around the cylin-
der to
be drawn in along
with cold
outside
air.
The carburetor
preheating flap must
be closed at tempe-
ratures above
+20°C (70°F)
to
avoid engine
running
problems.
To do this, remove
the carburetor box
cover
and
use
the
carburetor
screwdriver
to press
down
the flap until
it
snaps into position. Refit
carburetor box
cover.
Note:
The cylinder
shroud has been
cut
away in the
illustrations
for the sake
of clarity.
