MAINTENANCE
Wet Fouled
The insulator tip is black. There
may be a carbon layer over the
entire nose. Generally, the
electrodes are not worn. Causes
could be excessive idling, idle
too low or too rich, or weak
ignition output.
Fuel Valve/Fuel Lines
The fuel valve and the fuel lines
should be inspected regularly.
Special attention should be given
to the system’s fuel line
condition after periods of
storage. Normal deterioration
from weather and fuel
compounds can occur.
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.
It is the Polaris dealer’s responsibility to ensure that the correct main
jets are installed in each machine for your area of operation.
Carburetor adjustments should be performed only by a
knowledgeable service technician at a Polaris servicing dealer
using the proper tools, procedures and specifications.
