TO ADJUST CARBURETOR
The carburetor has been preset at the

may be required to compensate for
differences in fuel, temperature, altitude
or load. If the carburetor does need

of fuel to the engine giving a richer fuel/
air mixture.

and the seats in carburetor may result if
screw is turned in too tight.
