COMMON PROBLEMS
COMMON CAUSES
ENGINE WILL NOT START.
(Check the Engine Manual for more
details.)
• Refer to the section “Operation” in this manual to verify engine
starting procedure.
• Check the spark plug connection.
• Check that throttle lever is set to the “FAST” position and the choke is
“ON”.
• Check the level of fuel
• Check fuel valve is “ON”.
ENGINE STARTS BUT DOES NOT
RUN PROPERLY OR HAS NO
POWER.
(Check the Engine Manual for more
details.)
• Make sure the throttle lever is not set to the slow setting or the choke
still in the “ON” position.
•
Turn the machine off and check the air filter. If it is dirty clean or
replace it according to the Engine Manual.
• Check the oil level in the engine. Add if necessary. If the oil is too
full drain the oil to the proper level.
• Check to make sure there is enough fuel. Also make sure the fuel
is not old, dirty or the machine has not been stored beyond a month
with the same fuel in it.
• If the engine still has problems contact your dealer for service.
ENGINE HAS SMOKE COMING FROM
IT.
(Check the Engine Manual for more
details.)
• Check to make sure the machine is not running on “CHOKE”

Check to make sure the oil is not overfilled.
•
Check the air filter for debris and clean if necessary.
• Check the engine for debris build up around the exhaust system.
MAKE SURE THE ENGINE HAS HAD THE PROPER TIME TO
COOL BEFORE TOUCHING HOT PARTS.
• If there is still smoke coming from the engine contact the nearest
dealer for service.
ENGINE RUNS AND STARTS BUT
THE MACHINE WILL NOT GO
FORWARD OR IN REVERSE.
• Check that the free wheel lever is pulled out.
• Check to make sure the direction lever is being pressed far enough
down or pulled up to make the machine move.
• With the engine off and check the transaxle belt is not broken or
fallen off the pulley. Replace belt if necessary.
• Make sure nothing is lifting the machine up off the wheels.
MACHINE IS DIFFICULT TO GET INTO
REVERSE OR FORWARD.
• Check linkage for free operation.
THE BELT IS FRAYED OR KEEPS
COMING OFF THE PULLEY.
• Check the pulley to make sure it is free from damage such as a nick
or crack. If the pulley feels rough call a dealer for service and a
replacement pulley.
• Check the belt for wear and damaged spots. If there are signs of
damage or wear on the belt, replace with the correct type of belt.
• Check the belt tension. If V-belts are under tensioned, they can slip.
Slippage generates heat and will result in cracking and belt failure.
Properly tensioning and aligning a belt drive will allow the belt drive
to perform at it’s maximum level. If belts are over-tensioned, belt and
bearing life can be reduced.
• If the belt and pulley appear to be in good condition, contact your
dealer for service.
