9. EASY TROUBLESHOOTING

WHEN ENGINE WILL NOT START :
Perform the following checks before you take the engine to
your Robin America service dealer. If you still have trouble after
completing the checks, take the engine to your nearest Robin
America service 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.
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 valve 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.
