IGNITION SYSTEM INSPECTION AND SERVICING
The circuit working principle is shown in the picture.
IGNITION TIME INSPECTION
The CDI ignition system has already been adjusted in the factory,
so there is no need to readjust it. If inspecting ignition function is
necessary, use the following steps to inspect ignition timing.
• Remove the ignition timing hole cover (or remove the fan cover).
• Rotate the generator rotor, and align the “F” mark on the rotor with the crankcase timing ignition
mark.
• Clip the ignition timing indicator light wire clip on the high- voltage end of the ignition coil.
• Start the engine and let it idle. At this time, observe if the mark on the crankcase aligns with the
“F” mark on the rotor.
$
difference between ±3° indicates correct
ignition timing; on the contrary, if it is more than ±3°, the timing should be adjusted.
• Slowly increase the engine rpm (when the 150 model increases to 5000 r/min), at this time, if
the mark on the crankcase aligns with the rotor ignition advance angle mark, the advance angle
device is good; if not, it should be adjusted or replaced.
• When adjusting, the trigger winding can be loosened to adjust the angle between it and the igni-
tion charging coil to adjust the ignition time.
IGNITION SYSTEM INSPECTION
• When the spark plug does not spark, ¿ rst inspect the wires. If the connecting part is loose, or
the contacts are bad, etc., follow the electric circuit and use the method of measuring the voltage
of every point to determine the trouble. Please refer to the previous picture for the following
inspection.
• Remove the old spark plug. Install a new one, if plug is bad.
