TROUBLESHOOTING

Engine Troubleshooting

Problem

Probable Cause

Solution

Engine turns 
but fails to start

Faulty ignition

• Remove spark plug(s) and replace 

with new plug(s). If engine still fails 
to start, check for spark; if no spark 
SEE YOUR DEALER.

No fuel to engine

• Make sure the fuel valve is ON. 

Check tank level and fill up with cor-
rect fuel.

• Ice in fuel line, filter, or pump. On the 

standard POLARIS carburetor, the 
choke will not function with the throt-
tle depressed. See second item under 
“Probable Cause” of “Engine contin-
ually backfires”.

Flooded engine (normal 
situation caused by too 
much choking)

• Hold throttle open, crank engine sev-

eral times (may be necessary to 
change plug(s), however, the plug(s) 
may operate satisfactorily when 
dried).

Poor engine compression • Running too lean a mixture (too small 

a main jet will cause seizure resulting 
in loss of power). SEE YOUR 
DEALER. This indicates a major 
engine problem that must be repaired 
before engine is run.

Engine lacks 
power

Fouled or defective 
spark plug

• Change and test operation.

Fuel filter (loss of high 
RPM power)

• Check fuel filter flow. Disconnect 

hose and drain about 1/2 cup. Fuel 
flow should be steady and encompass 
the entire diameter of fuel line. If not, 
replace filter.

Incorrect clutching

• SEE YOUR DEALER.

Carburetor and fuel 
pump

• There’s no adjustment to change 

power output. SEE YOUR DEALER.

Engine 
continually 
backfires

Faulty plug(s)

• Change plug(s)

Carburetor

• Dirt or ice in fuel system. (Deicer 

should be added to non-ethanol fuel 
at all times for assurance against fuel 
line icing.)

Engine requires 
more than 
normal pulls to 
start

Poor gasoline or not 
enough fuel getting to 
engine

• Replace with fresh winter fuel.

12 MONTH LIMITED WARRANTY on all components of your POLARIS vehicle 
against defects in material or workmanship. This warranty covers parts and labor 
charges for repair or replacement of defective parts and begins on the date of purchase 
by the original retail purchaser. This warranty is transferable to another owner during the 
warranty period through a POLARIS dealer, but any such transfer will not extend the 
original term of the warranty. The duration of this warranty may vary by international 
region based upon local laws and regulations.

THIS WARRANTY MAY BE VOIDED BY ANY UNAPPROVED MODIFICATIONS 
TO THIS VEHICLE THAT AFFECT POWERTRAIN, EXHAUST, CHASSIS OR 
SUSPENSION.

Registration

At the time of sale, the Warranty Registration Form must be completed by your dealer 
and submitted to POLARIS within ten days of purchase. Upon receipt of this 
registration, POLARIS will record the registration for warranty. No verification of 
registration will be sent to the purchaser as the copy of the Warranty Registration Form 
will be your proof of warranty coverage. If you have not signed the original registration 
and received the customer copy, please contact your dealer immediately. NO 
WARRANTY COVERAGE WILL BE ALLOWED UNLESS YOUR VEHICLE IS

without proper dealer set-up will void your warranty coverage.
