9. EASY TROUBLESHOOTING
WHEN ENGINE WILL NOT START:
Perform the following checks before you take the engine to your Subaru Robin dealer. If you still have trouble after completing
the checks, take the engine to your nearest Subaru Robin dealer.
1. Is there a strong spark across the electrode?
1. Is the stop switch at the “ON” (I) position?
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.
Then ignition system is faulty if there is no spark with a new spark plug.
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 rmly. 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 ve 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.
• Wipe up 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.
