If the engine does not start, stop and try again.
If the engine does not start within 5 seconds (check that gasoline flows to the carburettor),
stop the procedure and try after about 15 seconds. Short and frequent tries are better
than long ones.

ENGINE RUNNING-IN
The running-in must be made following a few basic rules :
1.
Carburation setting. Start with basic setting on the rich side.
2.
Warm the engine gradually for 5 minutes, driving some laps at low speed, smoothly
closing and opening the accelerator (if a tachometer is installed, never exceed
9.000 ÷ 10.000 RPM). Never keep the same RPM for a long time but alternate the
speed.
3.
Gradually increase the vehicle speed for about 5 minutes (with ¾ throttle opening).
Never keep the same RPM for a long time but to alternate it.
4. Increase the speed driving some laps, for about 5 minutes (with acceleretor fully
opened on circuit twisty parts and enrich the carburation at half straight (cover with
the hand the inlet hole on the intake silencer for an istant, keeping the throttle open).
WARNING :
Once the running-in is over, with cold engine, check the torque of exhaust pipe nuts as
during the 1st running-in, the nuts can loosen (refer to the attached table).
3.5- INLET SILENCER
Make sure that the inlet holes of the inlet silencer are towards the upper side and they
are not covered. Make sure that the fixing strapis not loosen and that the inlet silencer is
well fastened to the chassis through the specific strap.
Occasionally, check the presence of oil deposits in the inlet silencer. If necessary,
remove the manifold with filter and clean the inside with gasoline or a diluent.

EXHAUST SYSTEM WARNINGS
Make sure that the silencer fixing springs are well hooked. In case of damage replace
the broken springs. Never race the kart without the two spring well hooked, as the
silencer could vibrate under the standard limits.
It is recommended to open the exhaust pipe end every 10
y
15 hours and make sure that
the holes on the counter cone are not obstructed by incrustation.
