6.6 IGNITION SYSTEM
GENERAL INFORMATION
The ignition system has a flywheel with an electron-
ic coil which supplies high voltage to the spark plug.
The starting system can malfunction in the following
ways:
• the engine does not start (if not due to another
cause):
= no spark on the spark plug due to a faulty coil
[
6.6.A];
= coil to earth [
6.6.B and 6.7.B];
= incorrect adjustment of the air gap [
6.6.B];
= faulty spark plug or wrong distance between
the electrodes [
6.6.A];
= oxidized or loose contacts [
6.6.B].
• engine runs irregularly (if not due to other caus-
es):
= incorrect adjustment of the air gap [
6.6.B
];
= oxidized or loose contacts [
6.6.B].
For access to the coil and the flywheel, remove the
upper conveyor.
SERVICING PROCEDURES
A) Checking the efficiency of the ignition
system
1 Dismount the spark plug (1) and look at the
colour on the end of the thread. This can give
you a good idea of the carburation:
–black = mixture too greasy due to clogged air
filter;
– nut brown = regular carburation.
Replace the spark plug if the electrodes (2) are
burnt or if the porcelain is broken or cracked.
WARNING! Fire hazard:
– do not check the ignition system if the spark
plug is not screwed in place;
– always use the specific tool for the spark test.
2Connect the tester (3) to the spark plug cap (4)
