The approach of real motoring
weather should mean the speedy
overhauling of all cars. Carbon may
be found in many engines, and every
trace should be removed before the
season of long tours and runs is here.
OF course, here and there is an
owner who has everything adjusted
to a nicely and drives his car with a
'sweet-running" engine for 10000
1000 and even 5000 miles, without
the necessity of taking off the cylinder
head. Even though the necessity for
carbon removal does not exist that
is to say, even though the carbon has
not had a sufficiently negative effect
on the operation of the engine to
make its presence felt-it is a fact
that its removal will go far toward
making even sweet running en-
CINE run more "sweetly."
OF course, when alcohol or some
other clean burning fuel takes the
place of gasoline, at least one of~the
contributory causes of carbone forma-
ton will be eliminated; but far re-
moved as the period seems or is,
even further removed is the time

of strictly non-carbon deposing quail

The method to be followed in clean

much upon the amount and nature of

Before the real onslaught is made
| it is a good pla to soak all the parts

This will allow a complete penetra-
/ ton to take place.
In the piston ring grooves or slots
will be found a good share of carbon.
slots attacked with emery cloth folded
over a thin stick, care being exercised
/ so that the metal will not be rubbed
away in the process, for then the
rings will fit loosely and cause leak
age. Be sure that the very last trace
of abrasive is removed before the pis-
ton sings are assembled.
OF course, the rings should be simi-
larly treated, for dirty rings are liable

No matter whether or not a sepa-
