WHEN ENGINE WILL NOT START:
Perform the following checks before you take the engine to your Robin dealer.
If you still have trouble after completing the checks, take the engine to your
nearest Robin dealer.
Is there enough compression?
If the spark plug is loose, tighten it.
Is the spark plug wet with gasoline?
1. 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 throttle body and fuel strainer intake.)
3. In case the engine does not start with well supplied fuel, try using fresh fuel.
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
Robin dealer.
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.
