Problem |
Possible Causes |
Probable Solutions |
|
Engine
will not start |
FUEL RELATED: 1.
No fuel in tank or fuel valve is in “OFF” position.
2.
Low quality, stale, dirty or deteriorated gasoline. 3.
Choke not in START position, cold engine. 4.
Carburetor not primed. 5.
Dirty fuel passageways.
6.
Carburetor needle stuck. Fuel can be smelled in the air. 7.
Too much fuel in chamber. This can be caused by the carburetor needle
sticking.
8.
Intake valve stuck open or closed. 9.
Clogged Fuel Filter. |
FUEL
RELATED: 1.
Fill fuel tank with fresh 91+
octane unleaded stabilizer-treated gasoline and turn fuel valve to “ON” position. Do not use gasoline
with more than 10% ethanol (E15, E20, E85, etc.). 2.
Drain fuel tank and
carburetor; fill with fresh fuel.
3.
Move Choke to START position.
4.
Pull on Starter Handle to
prime. 5.
Clean out passageways using
fuel additive. Heavy deposits may require further cleaning. 6.
Gently tap side of carburetor
float chamber with screwdriver handle.
7.
Turn Choke to RUN position.
Remove spark plug and pull the start handle several times to air out the
chamber. Reinstall spark plug and set Choke to START position. 8.
Contact the distributor or
after-sales service.
9.
Replace Fuel Filter. |
|
IGNITION
(SPARK) RELATED: 1.
Spark plug cap not connected
securely. 2.
Spark plug electrode wet or
dirty. 3.
Incorrect spark plug gap. 4.
Spark plug cap broken. 5.
Incorrect spark timing or
faulty ignition system. |
IGNITION
(SPARK) RELATED: 1.
Connect spark plug cap
properly.
2.
Clean spark plug.
3.
Correct spark plug gap. 4.
Replace spark plug cap. 5.
Have qualified technician
diagnose/repair ignition system. |
|
|
COMPRESSION
RELATED: 1.
Cylinder not lubricated. Problem
after long storage periods. 2.
Loose or broken spark plug. (Hissing noise will
occur when trying to start.)
3.
Loose cylinder head or
damaged head gasket. (Hissing noise will occur when trying to start.) 4.
Engine valves or tappets
mis-adjusted or stuck. 5.
There is liquid in the
cylinder, causing the cylinder to be unable to compress.
6. The
piston is stuck due to poor lubrication.
|
COMPRESSION
RELATED: 1.
Pour tablespoon of oil into
spark plug hole. Crank engine a few times and try to start again.
2.
Tighten spark plug. If that does not work,
replace spark plug. If problem persists, may
have head gasket problem, see #3. 3.
Tighten head. If that does not remedy
problem, replace head gasket.
4.
Have qualified technician
adjust/repair valves and tappets. 5.
Remove the spark plug cap and
use tool to remove the spark plug. Then use a flashlight to check if there is
liquid in the cylinder. If you see liquid
inside, move the generator to an open area outdoors, keep your face away from
the spark plug hole, and then slowly and gently pull the starter handle. If
you no longer feel the sticking, quickly pull the handle several times to
flush the cylinder. The liquid in the cylinder will spray out of the spark
plug hole. After completing this
operation, reinstall the spark plug and securely cover it with the spark plug
cap. 6.
The piston has been operating
for too long without proper lubrication, leading to overheating and the
piston seizing against the cylinder wall. Pour a teaspoon of
engine oil into the combustion chamber through the spark plug hole and let it
sit for about an hour. Then, try gently pulling the starter handle while the
spark plug is still removed to see if the oil can allow the piston to loosen
by itself. If it is still seized,
the engine is no longer operational and needs to be completely replaced. |
