4. WHEN ENGINE DOES NOT START :

Perform the following checks before you take the pump to your Robin dealer. If you still have trouble after completing the checks, take the pump to your nearest Robin dealer.

(1) Is there a strong spark across the electrode ?

■Is the stop switch at position “ I ” (ON)?

■Remove and inspect the spark plug.

If the electrode is fouled, clean or replace it with new one.

■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?

■Is the fuel cock opened?

■Choke (close choke knob) 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.

■When the electrode is dry, check where the fuel stops. (Check the fuel intake of the carburetor and fuel strainer intake.)

■In case the engine does not start with well supplied fuel, try using fresh fuel.
