idle setting (50 SX)
S03218-10
The idle setting of the carburetor has a big influence on the start-
ing behavior, stable idle speed, and the response to throttle open-
ing. This means that an engine with a correctly set idle speed will
be easier to start than one with an incorrectly set idle speed.
Info
The carburetor and its components are subject to increased
wear caused by engine vibration. Wear can result in mal-
functioning.
The idle speed is adjusted using the idle speed adjusting
screw

.
The idle mixture is adjusted using the idle air adjusting screw
