you consider the more efficient, ker-
osene or denatUred alcohol for in |.
jecting into the cylinders Of a hot I
engine to loosen the carbon? What
is your opinion Of the chain carbon I
remover which is dropped into the
opening through the plug opening. /
engine started and run for a few
minutes in order 10 cause the piston
TO throw the chain against the head, /
thus chipping off the carbon?
IT.
Kerosene and alcohol seem to
have equal value The chain loosens
the carbon. which must then pass
through the muller, which it may
clog. Better have it burned out,
with oxygen or use kerosene or al
cohol once a week to reduce accu-
mutation.
Motor Department.-Pleas tell
me how % tell which cylinder of
Ford is losing compression. When
L crank over by hand two revolutions
I notice one of the cylinders is weak,
but do not know which one it is.
Below we give several methods
G)While Cranking slowly, note
which intake valve opens. As soon
as it is closed the cylinder is on the
compression stroke. CD Bubbles
through the oil that sometimes ac-
cumu!ates around the spark plugs
show the compression stroke. CD
The ignition spark may be used as
guide in case you are sure il is
correct. buts this requires a battery.
ca Use a set Of printing plugs.
Close one at a time and crank en-
CINE. comparing resistance Of one
cylinder with the other CD Or re-
move all spark plugs but one and do
the same. moving it from one cylin
der to the other. (6)Wa-ch opening
OF exhaust valves. If no. 1 exhaust
valve is open, No. is on compress
sion, if No. is open. No. > is on
compression, and vice versa.
Motor Department:-Plea let me
know how 10 make the chain of my
timing gears run more quietly 1T
makes a terrible Sattle. which is
very annoying. My car is a 1915
which has been run $4,000
miles. n. o.
This is due to normal wear. but
may be silenced by adjustment
Some engines have an idler running
against the chain which may be set
up to take in the slack. In your
case the chain will have TO bs re-
placed by a new one.
Motor Department:-In shifting
gears on my little six Buick the con
troll lever sticks in one. When chang
ing to second goes in O. X. Also
from second to third.
FARMER.
This is due TO the gear shift lock
being a little too tight. 1t will dis
appear after a while.
Motor Department:-Wiu YOU
kindly advise me in your valuable
co.umn how TO time a Splitdorf Dixie
magnetic. model 40 high tension. on
an Overland car? | removed the
magnetic without marking II, and so
need help to put it back. r. T.
Bolt magnetic on base, but leave
armature shaft free. Crank engine
and note which way the drive shaft
for magnetic revolves. Set No 1
cylinder on firing dead center (be-
tween compression and power
strokes). Retard spark advancer on
magnetic by turning it I'm the same
direction that armatI,re is to turn.
Revolve armature Of magnetic as it
should go until circuit breaker
points are about to open. Fasten
armature 10 drive shaft. Note which
contact of distributor will get cur
rent from distributor arm. Connect
that contact 10 No. l spark plug.
Note that distributor arm revolves
in opposite direction OF armature.
Connect next distributor contact to.
No. spark plug. next TO No. 4. and
last 10 No. >. Run wire from arma-
from switch TO ground on engine
frame.
Motor OBSERVATION-DISCLOSURES COINS
at about fifteen miles an hour 1 have
a chattering sound from rear OF car,
generally when l am going down
grade. Please state cause. What
do YOU mean when you say piston
slap? have noticed this in your
columns at different times. I have
a sizzling sound from my engine
when I crank by hand, located in
printing cup; seems 10 be air. Is
there any harm in this? Car seems
to labor very much on any hill. Also
on taking curves 1 find it has not
very much pickup TO it, Car is
1914 Chandler six. 1 thank YOU
in advance
The chattcring is due 10 some part
