MAINTENANCE
Checking and adjustment of the
throttle wire
If the engine does not respond as it should do when
the throttle lever is moved or if the top speed is not
reached, the throttle wire may need adjusting.
1. Loosen the clamping screw (by the arrow), and
slide the throttle to the choke position.
Replacement of the fuel filter
Replace the pipe fitted fuel filter every 100 running
hours (once per season) or more frequently if it is
clogged.
Replace the filter as follows:
1. Fold open the engine cover as described on
page 21.
2. Move the hose clips away from the filter. Use a
pair of flat pliers.
3. Pull off the filter from the hose ends.
4. Press in the new filter on the hose ends. If
necessary soap solution can be applied on the
filter ends to simplify fitting.
5. Push the hose clips back on the filter.
2. Pull the throttle wire’s casing as far as possible
to the right and check that the choke is fully
actuated.
3. Tighten the clamping screw.
4. Pull back the throttle to the full throttle position
and check that the choke is no longer actuated.
