NOTE: Prior to doing step 3,
clean the air silencer thoroughly.
3. Remove the spark plugs from

GASOLINE-OIL
Recommended Gasoline
(Carbureted Models)
The recommended gasoline to use in
these snowmobiles is 87 minimum
octane regular unleaded. In many
areas, oxygenates (either ethanol or
MTBE) are added to the gasoline.
Oxygenated gasolines containing up
to 10% ethanol or up to 15% MTBE
are acceptable gasolines; however,
whenever using oxygenated gaso-
lines, the carburetor main jet must
be one size larger than the main jet
required for regular unleaded gaso-
line. For example, if a 400 main jet
i s r e c o m m e n d e d f o r r e g u l a r
unleaded gasoline, a 410 main jet
must be installed if using an oxygen-
ated gasoline.
When using ethanol blended gaso-
line, it is not necessary to add a gas-
oline antifreeze since ethanol will
prevent the accumulation of mois-
ture in the fuel system.
! CAUTION
C a r e m u s t b e t a k e n w h e n
installing the hose that it does
not sag below the entrance/exit
ends. If there is a “valley” in the
hose, freezing may occur.
! CAUTION
Do not use white gas or gaso-
lines containing methanol. Only
Arctic Cat approved gasoline
additives should be used.
