MAINTENANCE
Checking and adjustment of the
throttle wire
If the engine does not respond as it should when
the throttle lever is moved, or if it produces black
smoke or does not reach top speed, the throttle
wire may need adjusting.
1. Release the clamping screw (see arrow) and
push the throttle control 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. Raise the engine cover as described on page
18.
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.
4. Pull the throttle control back to the full throttle
position and check that the choke is no longer
activated.
2. Pull the throttle wire’s outer casing to the far
right and check that the choke is fully activated.
3. Tighten the clamping screw.
