Air Silencer

Inspection
Since the air silencer is only available as an
assembled component, no attempt should be
made to disassemble it. If a problem with the
silencer is suspected, there are a few checks that
can be made.
1.
With the silencer removed, check for holes or
cracks in the silencer. If a defect is found,
replace the silencer.
2.
Shake the silencer to check for any loose
baffles or silencer internals. There must be
no loose components.
3.
Periodically clean the intake silencer by
blowing fresh air through both the silencer
and air intake hose .

General
The air intake silencer used on the 1978 Arctic
Cat snowmobiles (most models) is a specially
designed component used to silence the incom-
ing fresh air and also to catch the fuel that "spits
back" out of the carburetors. The carburetor is
calibrated with the air intake silencer; thus, the
engine must never be run with the air silencer
removed.
79
.Oil models equipped with a silencer, the air
Intake silencer must be,secured to the
carburetor whenever .the engine is run or
when the carburetor is being adjusted.
If
the .
silencer Is removed and the engine is run,
poor performance will result. Therefore, DO
NOT run the engine when the intake silencer
is removed from the carburetor.
