Distributor
The distr ibutor
is a solid state type without breaker points and
therefore requires no adjustment.
It consists of a cap, rotor, signal
generator, igniter and centrifugal advance system.
The signal generator consists of a signal rotor, magnet and pickup
coil.
The magnetic flux from the magnet flow through the pickup coil
and signal rotor.
When the signal rotor is dr iven, the amount of
magnetic flux through the pickup coil varies and an electric signal is
conducted at both ends of the pickup coil and sent to the igniter.
The centrifugal advance controls the signal generator timing so as to
control the ignition timing according to the engine speed and load.
Checking the Distributor
1.
The cap and rotor should be examined when servicing the spark
plugs and checked for cracks and that the terminals are clean and
free of corrosion.
Replace if defective.
2.
Remove the high tension cord from one of the spark plugs and hold
its tip 5 - 10
mm
(0.20 - 0.40 in) away from a grounded surface.
Crank the engine.
An intense bluish-white spark should be visible
under normal conditions.
If no spark is visible, it is possible
that the igniter and/or pickup coil are defective.
Replace both
the igniter and pickup coil after checking the overspeed module,
coil and high tension wiring and recheck.
Ignition Timing
1.
Attach a timing light to #1 spark plug and mark the front crank-
shaft timing groove and the timing mark on the scale embossed on
the engine front cover.
2.
Start the engine and warm it up to normal operating temperature.
3.
Using the
timing light,
align the timing groove
crankshaft pulley with the proper
timing mark on
timing scale embossed on the engine front cover.
