or abnormalities in engine performances,
- Pick up fuel strainer carefully through fuel inlet port
with a piece of steel wire or the like.
— When strainer is dirty, wash it in gasoline.
SPARK PLUG
CYLINDER FINS
MUFFLER AND EXHAUST PORT
• Check periodically.
— The standard spark gap is 0,6—0,7 mm (0.023-
0.028 in,}.
— Correct spark gap if it is wider or narrower than the
standard gap,
— When it is deposited with carbon or stained, clean it
before fitting to engine.
• Fastening torque = 145—155 kg.cm (125—135 in.lb).
(Caution! Do not over tighten plug.
• Check periodically.
— Clogged fins result in poor engine cooling.
- Clean passage of air between cylinder fins to let cooling
air pass easily.
• Carbon deposit in cylinder exhaust port and muffler will
cause drop of engine output and sparking from muffler.
— Muffler can be removed by taking off muffler cover.
— Be careful not to scratch cylinder or piston when
cleaning cylinder exhaust port.
TROUBLE SHOOTING
• FAILURES such as difficulty in starting engine, irregularity in functions and abnormality in blowing performances
can normally be prevented completely if a little attention is paid in advance,
• Such failures can be readily disposed of even by a beginner.
• When engine does not function properly, check following 3 points systematically in particular:
— Whether compression of engine is adequate or not.
— Whether fuel system is in good condition and fuel is supplied fluently, or not.
— Whether electrical system is in good condition and spark plug sparks correctly, or not,
• When there is serious trouble with the unit, do not try to repair by yourself, but have your distributor or dealer do it
for you.
• Details of TROUBLE SHOOTING refer to Table 1 and 2.
— Refer to chart to locate the problem and repair as necessary.
