GREATEST WORRY
FOR A M0T0RIST
Carbon Will Form in Best of Com
bustion Chambers and Cause
Much Trouble.
SEVERAL WAYS OF REMOVING
Experienced Man Says Best and Sur
est Way Is Use Of kerosene-Pour
Liquid in Gradually and Open
Throttle Slowly.

Carbon is one Of the greatest wor-
ries Of the motorist. 1t will form In
the best of combustion chambers.
This substance Is deposited through
imperfect combustion of the cylinder
oil and gasoline. Dust is drawn into
the motor and adheres to the first oil
surface it strikes, adding to the accu-
mutation of the piston head Eventu-
ally this deposit becomes so deep that
1t is incandescent causing premature
ignition of the fuel. 1t is this feature
that will prevent any motor running
smoothly
There are many ways of removing
carbon. 1t may be scraped out with
tools designed for the purpose There
are several sorts of chemical carbon
removers which can be injected into
the combustion chamber for the pur-
pose of loosening the carbon and per-
mitting 1t to be blown out the exhaust.
With some types of motors it is pos
sible to drop a small chain in the com
bustion chamber and let it scrape the
carbon off as 1t flies around under the
impulse of the piston.
Surest Carbon Remover.
However, the experienced motorist
says the best and surest carbon remov-
er is dose of ordinary kerosene.
When the engine Is hot after a run
feed about three or four ounces of kerr
osene through the air vent on the in
take manifold or through the air ID
take of the carburetor while the en-
CINE Is idling. The kerosene should
be poured In gradually and the throt
tie opened very slowly, which draws
the kerosene into the cylinders in
larger quantities than can be vapor-
lied and burned at once. In a few
minutes the excess kerosene is being
churned up and down in the cylinders,
soaking the valve seats and spark
plugs.
Many car owners inject the kerosene
through the petcocks, but the method
described above has the advantage of
uniform application to the valves.
When the oil is put in by way of the
petcocks it is likely to run down one
side of the carbon deposit, leaving the
other side untouched.
Prevent Formation.
| BY giving the motor dose of kero-
sene once week 1T Is possible to pre-
vent the formation of carbon deposit.
One Kansas City motorist has a small
tank of kerosene installed in the front
of his car. Every day as he draws
near his home, he switches from his
gasoline feed to the kerosene for ten
minutes running. He claims this
practice has relieved him from all car
bon troubles and that his engine runs
as well as when new.
Mixtures of various sorts have prov
en- good carbon removers. Alcohol and
kerosene In proportions of three to
one make a good carbon solvent, mo-
florists say, and another good carbon
cleanser is made of two parts acetone,
two parts kerosene and one part ether.
In preventing the formation of car
bon, the use of good cylinder oil and
the correct adjustment Of the carbure-
tor is necessary The best advice Is
buy a standard brand of oil in guam
tity recommended for use in the par
ticular make and model of car. Some
cars use different weight oil in sum
mer and winter. AS The car gets older
and the parts become thoroughly worn
in and a trifie loose, a heavier oil is
often beneficial, motorists say.
