Troubleshooting Table
SYMPTOM
POSSIBLE CAUSE
The engine won’t start.
(Please refer to the
engine user manual
for engine-specific
procedures.)
Is the ignition switch in the “ON” position?
Is the fuel shut-off valve on?
Are you using fresh, clean fuel? If the fuel is old, change it. Use a
fuel stabilizer if you keep fuel longer than 30 days.
Is the spark plug clean? If the spark plug is dirty or cracked, change
it. If it’s oily, leave it out, hold a rag over the plug hole and pull the
recoil cord several times to blow out any oil in the cylinder, then
wipe off the plug and reinsert it.
Is there sufficient oil? Check the engine oil level and if necessary
top up to the correct level.
Is there dirt in the carburetor? Undo the bolt holding the float
chamber to the carburetor, empty out any fuel and clean the inside
using fresh clean petrol. Remove the jet in the bottom of the
carburetor and clean it. Refit the jet and the float chamber.
The engine lacks power
or is not running
smoothly.
(Please refer to the
engine user manual
for engine-specific
procedures.)
Check that the Throttle Lever is in the “Run” position.
Is the air filter clean? If it’s dirty, change it following the
procedure in the engine manufacturer’s owner’s manual.
Is the spark plug clean? If it’s fouled or cracked, change it. If it’s
oily, leave it out, hold a rag over the plug hole and pull your recoil
cord several times to blow out any oil in the cylinder, then wipe off
the plug and reinsert it.
Are you using fresh, clean unleaded gas? If it’s old, change it. Use
a fuel stabilizer if you keep gas longer than 30 days.
Does your engine have the right amount of clean oil? If it’s dirty,
change it following the procedure in the engine manufacturer’s
owner’s manual.
Check the oil level and adjust as needed.
