Times.-When a motor in use only
about three thousands miles de-
velops a knock in the cylinders
when under full power, and does
not develop the usual power to
climbs hills, what do you think is
the cause2 z. :.
The trouble you are experiencing
Is evidently due TO carbon in the
cylinders. Unless the valves of a
motor close properly there will be a
loss of compression with a CORES
pOnding loss of power. The knock
ing you have in the cylinder is
probably due to carbon. The car
bon causing preignition Of the gases.

Times.-My Ford car creeps for
ward when the pedal is held in neu-
trail position and to hold the car
still, 1 must apply the brake also.
G. r.
The Ford car uses a planetary
gear set controlled by contracting
bands for low and reverse speeds,
and il is very likely that the band
on the low speed drum is too tight,
and causes the car to creep forward
when the pedal is in neutral. This
band may be released by turning
the adjustment screw which pro-
jects through the gear case from the
second drum,

Times.-'My Buick car after running
about 1900 miles carbonizes rapid
ly with an attendant loss of power
caused by the valves being kept
open by the carbon caking on the
valves. How may 1 reduce this
rapid formation of carbon, or keep
1t from hardening? Z. +.
Carbon may be prevented from
forming rapidly by the use of the
proper grade of oil and a correct
carburetor adjustment. The use of
small quantity Of kerOsense poured
into the cylinders when the motor
is hot will soften the carbon de-
post, preventing caking. After run
ming 1000 miles you should expect
TO clean carbon. In fact the motor
should be cleaned and the valves
ground more frequently.
Motoring Department, The News
Times.-My six cylinder automobile
ran well up TO about a week ago
when the motor suddenly COM
menced 10 lose power. and from the
muffler, flame shoots out in a Sc
ries of explosions when the motor
is run. V. w.
The loss of power is very likely
caused by some of the cylinders
missing explosions with the result
that unburned gases are forced from
the cylinders. The unburned gas
passes into the muffler where it is
ignited by the following charges of
exhaust gases. This after ignition
of the gases probably is the cause
OF the flames flashing from the
muffler, and the fact that there are
series of these afterfrings, indi-
Gates a number of cylinders missing
fire. Clean the spark plugs and
contacts and trace for broken wires !
or connections. Place spark plugs |
on tops of cylinders and with igni- |
ton switch on crank motor and |
note if all the plugs are working
properly. Also clean and adjust DIS |
tributor joints.

Times.-Have had a garage man re-
pair the magnetic on my Overland !
automobile and since il has been re- |
placed il does not give a spark. Have |
since called in a magnetic repairman /
who has tested the winding OF the |
armature and says the magnetic is |
timed and the parts set properly |
Any suggestion you may offer will |
be greatly appreciated. A. L.
If the windings of the armature I
and condenser are in working order,
and interrupter points are properly |
adjusted and the magnetic timed |
properly it may be advisable to test
the strength Of the magnets. In re-
placing the magnets it may be pos
sible that opposite poles have been
placed on same side. When the
magnetic pull Of the magnets become
weakened il is necessary to have
them magnetized.

me know. in your Auto
terest. about the following: I have
a new 1917 Ford car run about 500
miles I find, after running about
35 miles IL Will jerk when in high
speed and not much power when
in low speed. 1 have taken out
spark plugs, taken them apart and
cleaned them. It ran .. X. for
about 80 miles, when 1 had TO take
them out again and clean them.
They were all covered with black
SCOT. The trouble is always with
the two front ones up near the ra-
diator-I 90 not know them by
number. 1 took all the oil out and
put in a pint of kerosene and let ii
run in through and out of the cock,
and put in fresh oil, so the oil gauge
showed three-quarters full. I open
ed the upper oil cock TO see if 1 had
enough, but il did not run out. 1
inserted 4 wire TO see that the hole
was not plugged up. About how
much oil should / have in same? I |
took this car 10 a garage to have
the gas regulated and see il il was
carbon trouble. They told me I'll !
the car wanted was work. This
same day had the spark plug
