Air-Intake Silencer
(120 cc)
The air-intake silencer is a specially designed compo-
nent used to silence the incoming fresh air and also to
catch the fuel that “spits back” out of the carburetors.
The carburetors are calibrated with the air-intake
silencer in position; therefore, the engine must never
be run with the air-intake silencer removed.
CLEANING AND INSPECTING
1. Check for holes or cracks in the silencer.
2. Periodically clean the silencer by blowing fresh air
through it.
