6. EASY TROUBLESHOOTING

WHEN ENGINE WILL NOT START:
■ Perform the following checks before you take the engine to your YAMAHA dealer.
■ If you still have trouble after completing the checks, take the engine to your nearest
YAMAHA dealer.
Is there enough compression ?
If the spark plug is loose, tighten it.
Is the spark plug wet with gasoline ?
1. Choke (close choke lever) and slowly start the engine for 2 or 3 seconds.
Remove the plug and check if its electrode is wet. If the electrode is wet, fuel is well
supplied to your engine.
2. When the electrode is dry, check to find where the fuel is restricted.
(Check the fuel intake of the carburetor and fuel strainer intake.)
3. In case the engine does not start with well supplied fuel, try using fresh fuel.
WARNING
Wipe off spilled fuel carefully before
checking the spark plug. Place spark
plug as far away from spark plug
hole as possible.
Do not hold spark plug by hand
while checking.
Is there a strong spark across
the electrode ?
1. Remove the spark plug and connect it to
the plug cap.
Turn key switch to "START" position
while grounding spark plug against
engine body.
2. Try with a new spark plug if the spark is
weak or there is no spark.
3. The ignition system is faulty if there is no
spark with a new spark plug.
Take your engine to your nearest
YAMAHA dealer.
