FUEL VALVE & FUEL LINES
CAUTION

regularly. Special attention should be given to the

Normal deterioration from weather and fuel compounds
can occur. Replace lines that show any signs of cracking
or leaking.

CARBURETOR

GENERAL CARBURETOR INFORMATION

The number size stamped in the end of the main jet indicates the
jet size which was installed at the time of manufacture.
The installed main jet is not necessarily correct for your
elevation.
WARNING
Carburetor adjustments should be performed only
by a knowledgeable service technician at a Polaris
servicing dealer using the proper tools, procedures
and specifications.

CARBURETOR ADJUSTMENTS

• Carburetor component changes for specific altitude and
ambient temperatures
• Choke adjustment
• Air screw settings, if applicable
• Idle RPM adjustments
• Throttle safety switch checks and servicing
• Throttle lever free play adjustment

ELECTRICAL

ELECTRICAL CONNECTIONS

Separate electrical connector blocks and clean corrosive build
up from connectors. Lubricate or pack connector blocks with
Nyogelt grease (PN 2871329) and re-connect. Replace worn or
frayed electrical wire and connectors. Be sure wiring harness is
properly secured away from sharp edges, steering linkage,
moving parts, and hot exhaust.

EXHAUST

EXHAUST INSPECTION

At approximately 50 hours it is a good idea to check the exhaust
system for wear or damage. To inspect, allow engine and
exhaust system to cool completely. Open the hood and inspect
the muffler and pipes for cracks or damage. Check for weak or
missing retaining springs or damper/support grommets.
WARNING
Exhaust system temperatures can exceed 900 F
(500 C). Serious burns may occur if this inspection
is performed without allowing adequate time for the
exhaust system to cool. Never perform this
procedure with the engine running.

CLEANING

AIR FILTER

NOTE: Do not operate a machine with the intake
filters removed in the summer. This may cause
carburetor intaking debris resulting poor fuel
economy or engine damage.

NOSEPAN CARE

If your nosepan becomes dirty with soot, you can use Polaris
Carbon Clean (PN 2872890) to remove the soot.
