TROUBLESHOOTING
Engine Troubleshooting
Problem
Probable Cause Solution
Engine turns but fails
to start
Faulty ignition
• Install new spark plug(s). If engine
still fails to start, check for spark. If
there's no spark, SEE YOUR
DEALER.
No fuel to engine
• Make sure the fuel valve is on.
• Use the choke. See page 60.
• Make sure fuel tank contains fuel.
• Ice may be in fuel line, filter or
pump. Add isopropyl alcohol to
fuel system. On the standard
Polaris carburetor, the choke will
not function with the throttle
depressed. See second item under
Probable Cause" of Engine Contin-
ually Backfires".
Flooded engine (too
much choke used)
• Hold throttle open, crank engine
several times (may be necessary to
change plug(s).
Poor engine com-
pression
• Mixture is too lean. A main jet that
is too small will cause seizure
resulting in loss of power. This
indicates a major engine problem
that must be repaired before operat-
ing. SEE YOUR DEALER.
Engine lacks power
Fouled or defective
spark plug(s)
• Replace the plug(s).
Fuel filter (loss of
high RPM power)
• Check fuel filter flow. Disconnect
hose and drain 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
• SEE YOUR DEALER.
Engine continually
backfires
Faulty plug(s)
• Change plug(s).
Carburetor / Fuel
System
• Dirt or ice may be in the fuel sys-
tem (add deicer to non-ethanol fuel
at all times to prevent icing).
Incorrect throttle
freeplay or faulty
switch
• SEE YOUR DEALER.
