ELECTRICAL SYSTEM
SPARK PLUG
Clean or replace and adjust spark plugs after
every 100 hours of operation. A wire gauge is
best for checking the spark plug gap. A flat gauge
should not be used unless the electrode surfaces
have been dressed with a small file to get parallel
surfaces between the center and side electrodes.
Set the spark plug gap by bending the side
electrode. All spark plugs, new or used, should
have the gaps checked and reset if necessary.

GAPPING THE SPARK PLUG
A. Spark Plug
B. Center Electrode
C. Side Electrode
D. Gapping Tool
The proper spark plug gap is 0.023 to 0.028 in
(0.58 to 0.71 mm) for gasoline, and 0.016 to
0.020 in (0.41 to 0.51 mm) for LPG engines.
To get good performance from the spark plugs,
follow these steps when installing the plugs.
1. Clean the spark plug seat in the cylinder
head.
2. Use a new seat gasket and screw the plug
in by hand.
3. Tighten the spark plugs to 22 to 28 ft lb
(30 to 38 Nm) with a socket wrench of the
correct size.
IGNITION SYSTEM
The engine ignition system is the breakerless
type. The ignition system needs no regular
maintenance. The magnet-to-ignition module gap
is 0.012 to 0.016 in (0.30 to 0.41 mm). When
adjusting, tighten module screws to 32 in lb (3.5
Nm).
STARTER
The starter motor brushes must be inspected after
every 400 hours of operation.
