SPARK PLUG
Keeping the spark plug in good condition
will reduce fuel consumption and increase
engine performance.
To perform the check, simply slide off the
electrical connection tube and unscrew the
spark plug. Examine the distance between
the electrodes with a feeler. This distance
should be from 0.5÷0.6 mm. If it is not,
it may be corrected by bending the earth
electrode.
Check as well that there are no cracks in
the insulation or corroded electrodes. If so,
replace immediately.
When replacing the spark plug, screw it
in by hand until it stops, then tighten with
a wrench.
WARNING:
Do not check while the engine is hot.
0,5÷0,6 mm
