"Carbnn. the bugbear of everyone
who drives a motor car, can be removed
from the cylinders Of automobile en-
zines by various methods. and the use
of various agents. In actual experience

fairly soft and before it has had time

sometimes find It

two or three ounces Of 1t are run
through the motor, either by way OF
the carburetor or a petcock placed IN
+be intake manifold, the motor being
speeded at the same time TO prevent
stalling. If this is done every day OF
