Regular maintenance tasks must be carried out at
specific intervals to retain the engine's performance.
10.1 CLEANING THE AIR FILTER
(FIGS.15 – 17)
A dirty, clogged air filter will restrict the air flow in to
the engine and will cause rough running. It will
increase fuel consumption and may result in starting
problems.
Attention:
Stop the engine before removing the air
filter assembly.
Set the choke lever
to the closed position
to prevent any debris entering the carburettor
inlet.
Turn
screw
on the air filter cover
anticlockwise to remove it.
Lift
cover
away at the bottom, then lift it
free from the tab at the top.
Remove the foam air filter element
.
Wash the element in warm soapy water to clean
it. Do not use solvents to clean it.
Allow the filter to dry 100% before refitting it on
to the engine.
– Refit cover
.
– Insert screw
and turn clockwise to
tighten. Replace the filter if it appears worn
or damaged.
10.2 SPARK PLUG MAINTENANCE
(FIGS.18 – 19)
Over time the spark plug can become contaminated.
This can be due to adverse running conditions such
as, working with part throttle for a prolonged period
or a fuel mix containing too much oil. This
contamination can build up causing the engine to
run roughly, reduce the fuel consumption or create
starting problems.
Without using any tools so as to avoid damaging
the H.T. lead, remove the lead
from the
back of the spark plug.
