KEROSENE CURES
CARBON TROUBLES
PARASITE OF MOTOR MAY BE DE
FEATED BY USE OF SIMPLE
METHODS.

Carbon is like a parasite; II eats the
life out Of motor. It's formation can
not be entirely prevented, but preven.
tive measures can lessen to a great de-
gree the dangers resulting from if and
the necessity for removing it. As "A
preventive measure the carbureter
should be adjusted to furnish as lean a
mixture as possible, because imperfect
carburetion resulting from a rich or
heavy mixture is one Of the prime
causes Of carbon trouble Road dust is
contributing cause Of carbon forma-
tion and this can be guarded against by
having the air intake on the carbureter
provided with very fine screen so that
the dust will not be drawn into the
combustion chamber with the mixture.
Il have found the use of kerosene a
valuable aid in preventing and curing
carbon troubles says a writer in Mo.
tor. About every 500 miles it is good
practice to squirt about gill of kero-
sene into the cylinders by means of the
priming cups after the motor has been
thoroughly warned up. 1t will also be
found very helpful 10 occasionally squirt
about a pint of Kerosene through the
air intake of the cafbureter while the
motor is running, open throttle and
muffler cut-Out to thoroughly flush the
motor. This may be done about every
500 miles and the necessity Of scraping
or burning the carbon out will not arise
so frequently.
Two Methods for Cleaning.
For cleaning the carbon out there
are two methods that / use according
TO the type OF motor. If the engine is
of the type with detachable head the
process Of removing the cylinder
head and scapping the carbon with a
sharp bearing scaper is a comparatively
easy one II the valves are to be
ground also, the method is by far the
best, because with the cylinder head re.
moved, the valves are readily accessible
and both operations can be accomplished
in minimum time.
For the type of motor without de.
tachable head the burning or oxygen
system has the advantages of speed and
thoroughness. The gasoline must first
be shut off at the tank and then the
motor should be run until the gasoline
in the carbureter and feed pipe is com
pletely consumed. a fire extinguisher
should be placed I'm a convenient posi-
tion ready for emergency and as an
added precaution a rubber apron should
be placed over the motor with the ex-
ception of the cylinder that is being
burned out Next the valve caps
should be removed from cylinder No
and then the motor should be turned
over by hand until No. piston reaches
top centre and both valves are closed
The cylinder is now ready for the actual
burning out process. The flame should
be directed into the valve pockets, etc.
and continued until the flame ceases
which is an indication that the carbon
is all burned. The remaining carbon
debris should then be blown out by
directing air pressure into the combus.
ton chamber and valve pockets When
No. / cylinder has been cleaned out,
proceed as before with No . and so on
until every cylinder Is free from carbon.
after the operation IS completed
whether the scraping or burning method
is used, a few drops OF kerosene placed
in the combustion chamber will help TO
clean thoroughly and start fabrication,
after which the oil in the crank case
should be drawn off and replaced with
fresh supply. The last operation will
be found TO be an economical one I'm the
lons run because oil loses it's lubricating
value in time and the sediment that IS
bound to collect may prove injurious"
