3. If parallelism is not within specifica-
tions, the parallelism must be cor-
rected by first loosening all the
engine mounting bolts (left side,
front, and right top rear). Then, pry
the front of the engine towards the
MAG-side of the engine compart-
ment. Next tighten the left-side
mounting bolts followed by the front
and right-top rear bolts. Re-check
the parallelism. If still out of specifi-
cation, repeat correction procedure.
CARBURETOR MAIN JETS
(Bearcat 570/T570 Model)
— Proper
carburetion is absolutely necessary to
obtain peak performance. Since ambient
temperature and operating altitude both
affect the main jet size needed for opti-
mum engine performance, the main jets
MUST be changed whenever the temper-
ature changes 20° F or whenever operat-
ing altitude varies by more than 1000
feet. The Carburetor Jet Chart on the belt
guard of the snowmobile identifies the
proper main jets to use under all operat-
ing temperatures and altitudes. Follow
the Carburetor Jet Chart carefully to
obtain peak engine performance and
avoid engine damage.
GASOLINE
— It is not necessary to
exceed the recommended 87 octane gaso-
line. Using a higher octane gasoline will
not increase overall performance; how-
ever, the TZ1 Turbo model will detect
lower octane gasoline and reduced
engine performance will result. It is rec-
ommended that 91 octane (minimum)
gasoline be used in the TZ1 Turbo mod-
els.
