Column 2 corresponds to a needle in the standard position.
Column 1 corresponds to a needle which is half a clip leaner.
Column 3 specifies the diameter of the first cylindrical part of the needle. The smaller the diameter of the first cylindrical
part of the needle, the richer the mixture. The larger the diameter of the first cylindrical part of the needle, the leaner the
mixture. The first cylindrical part of the needle has the greatest influence in the lowest load range.

The idle setting of the carburetor has a big influence on the starting
behavior, stable idle speed, and the response to throttle opening. 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 malfunc-
tioning.
