5. 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 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.

■

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

■

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