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.
