11. EASY TROUBLESHOOTING

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.
1. Is there a strong spark across the
electrode ?
(1) Is the stop switch at position " I " (ON)?
(2) Remove and inspect the spark plug.
If the electrode is fouled, clean or replace it with new
one.
(3) Remove the spark plug and connect it to the plug cap.
Pull the starter handle while grounding spark plug against
engine body. Try with a new spark plug if the spark is
weak or there is no spark.
The ignition system is faulty if there is no spark with a
new spark plug.
WARNING
Wipe out spilled fuel carefully before testing.
Place spark plug as far away from spark plug
hole as possible.
Do not hold spark plug by hand while pulling
recoil starter.
NOTE
The engine with oil sensor will stop automatically when
the oil level falls below the prescribed limit.
Unless the oil level is raised above the prescribed limit,
the engine will stop immediately after starting.
2. Is there enough compression?
Pull the starter handle slowly and check if resistance is felt.
If little force is required to pull the starter handle, check if
the spark plug is tightened firmly. If the spark plug is loose,
tighten it.
3. Is the spark plug wet with gasoline?
(1) Is the fuel cock opened?
(2) Choke (close choke lever) and pull the starter handle
five or six times. Remove the plug and check if its
electrode is wet. If the electrode is wet, fuel is well
supplied to your engine.
(3) When the electrode is dry, check where the fuel stops.
(Check the fuel intake of the carburetor.)
(4) In case the engine does not start with well supplied fuel,
try using fresh fuel.
4. Is the battery well charged?
If the battery for the electric starter is discharged, the engine
will not start.
