WHEN ENGINE DOES 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?
1. Pull the starter handle slowly and check if
resistance is felt.
2. If little force is required to pull the starter handle,
check if the spark plug is tightened firmly.
3. If the spark plug is loose, tighten it.
Is the spark plug wet with gasoline?
1. 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.
2.When the electrode is dry, check where the fuel stops.
(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.
Is the engine switch set ON?
WARNING
Wipe out spilled fuel carefully before checking.
Place spark plug as far away from spark plug
hole as possible.
Do not hold spark plug by hand while checking.
1. Remove the spark plug and connect it to the plug cap.
Pull the starter handle while grounding spark plug
against engine body using an insulated pliers.
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.
Is there a strong spark across the electrode?
