1- Stop the engine.
2- Remove the protection from the plug I.1.
3- Unscrew the plug with a spark plug spanner C.1
(FIG.C).
4- Inspect the spark plug for any possible cracks or
faults. Clean the spark plug with a brush and put
it back in place.
5- Check gap using a feeler gauge. Vary the gap by
moving the side electrodes. The correct gap is
0.70-0.80 mm.
6- Check that the ring above the spark plug is in
good condition. Screw it down using the spark
plug spanner to protect the stopper.
Comment: If you have to install a new spark plug,
turn it halfway until the spark plug is aligned with the
ring to get the right pressure. If the plugs are worn,
make only a quarter turn.
WARNING: Check that the spark plug is correctly
screwed in. If not, the engine might overheat.
Never use spark plugs with an inappropriate heat
range.
5.5 IDLE ADJUSTMENT - SEE FIG.J
To adjust idling:
1- Start up the engine outside and warm it up.
2- Put the throttle in the slowest position.
3- Turn the idle adjustment screw J.1 to get the
optimum speed.
Standard speed: 1400 +/- 150 rpm.
