8.2.3. CHECK THE SPARK
The most common problems when starting a machine
are produced by a dirty spark plug or bad. Clean spark
plug and check it regularly. Check the electrode gap is
correct (0,6 - 0,7 mm).
8.2.4. CLEANING THE CYLINDER FINS
The fins of the cylinder are in charge of refrigerating
the engine thanks to these being in contact with the
air. These fins should always be clean and without any
material that prevents the air flow. If the fins are not
clean and blocked with dirt, the engine will overheat
and could even break. Check these fins on a regular
basis.
8.2.4.1. VENTILATION OF AIR INTAKE TO ENGINE
Eliminate any dirt from the ventilation fins so that the
engine is not damaged and to avoid a possible fire.
