cylindrical part of the needle, the richer the carburation. The larger the diameter of the first cylindrical part of the
needle, the leaner the carburation. The first cylindrical part of the needle has the greatest influence in the lowest

402799-10
The idle setting of the carburetor has a big influence on the start-

This means that an engine with a correctly set idle speed is easier
to start than if the idle speed is set wrongly.
Info
The carburetor and its components are subject to increased
wear caused by engine vibration. Wear can result in mal-
functioning.
The factory setting for the carburetor is set for the following val-
