CARBURETOR
There are 2 types of carburetors, «SLIDE» or «ROTARY», the adjusting
principals of both carburetors are the same. The carburetor supplied on
the engine is preset at the factory, meaning that the original settings are
close to where they should be for normal operation.
On the carburetor you can find in general 3 to 4 adjusting possibilities
depending on the carburetor supplied with the engine.
