Spark plugs
The
type of spark plugs
to be used is indicated
at
page

The
spark plugs are best
cleaned with petrol
and
a

brush,
using a needle for the inner part.
In re-fitting the spark
plugs ensure they
are
pro-
perly started by hand

in
the tool kit.
If
not
properly

events,
the
plugs
have to be
replaced
every 10000 km (6000
miles
a.)
even
if
they
ap-
pear to be still in good conditions.
