SPARK PLUG CONDITION
NORMAL PLUG
The normal insulator tip is gray, tan or light brown. There will be few combustion
deposits. The electrodes are not burned or eroded. This indicates the proper
type and heat range for the engine and the service.
TIP
The tip should not be white. A white insulator tip indicates overheating, caused
by use of an improper spark plug or incorrect carburetor/throttle body
adjustments.
WET FOULED PLUG
The wet fouled insulator tip is black. A damp oil film covers the firing end. There
may be a carbon layer over the entire nose. Generally, the electrodes are not
worn. General causes of fouling are excessive oil or use of non-recommended
injection oil.
INTAKE FILTERS
The intake filters
q
limit snow
ingestion into the intake system.
When operating in loose powder
snow, check the filters
periodically for damage and to
remove any accumulation of
snow.
FUEL PUMP
All fuel pump service must be performed by an authorized POLARIS dealer. Do
not attempt to service the fuel pump.
