mattsr7
You have not said whether you are
obliged to retard the spark so far that
the power Is reduced. 1t may be that
the spark linkage is connected up so
that the spark ordinarily occurs too
early and that the lever must be re-
tarded all the way before the spark
occurs In the proper place. II this is
the case change the setting Of the
spark linkage so that when the motor
is cranked slowly the spark occurs at
dead center with the lever retarded.
Vary the adjustment Of your carbu-
rotor with the lever halfway advanced,
and then note whether the knocking
continues. Crank the motor slowly,
aud note which cylinders offer small
resistance to the pull Of the crank. II
all are strong then there are no leaky
valves, pistons or rings, but II one or
more are weak you should take your
car to a repair shop and have the trou-
BILE fixed.
Remove the radiator cap while the
motor Is running. and note whether
the circulation Of water seems free;
also feel the various parts Of the sys-
TEN and see whether there are any
wide variations In temperature or
whether the temperature is fairly uni
form all over the radiator and piping.
Big differences In temperature would
indicate lack OF circulation, caused by
sediment In the water jackets, loose
pieces Of hose In the passageways o.
dirt In the radiator. A thorough flush
ing OF the system should be sufficient
TO put II In good order. and IL 1t Is not
the car should be intrusted to a repair
man. A heavy coating Of carbon on
the cylinders will cause a knock, and
the remedy Is 10 remove the carbon.
Defective ignition, II it causes a knock,
should also cause a miss. Worn insula.
ton. loose connections, poor adjust
ment OF the vibrators, incorrect spark
gap. dirty plugs and cracked %porcelains
are the principal ways in which the
ignition may give trouble.
What are the advantages Of q float.
ing rear axlef
In the floating rear axle the shafts
are relieved Of all stresses but tor
sional ones, which Is quite an advan
tage. The shafts may be removed
without disturbing the wheels, ant
with a sufficiently large plate in thu
aifferential housing the differential II
self may be removed for inspection
In this type Of axle the shafts carr.
no weight and hence do nothing els
but turn the rear wheels.
What 10 the average life Of q spar

The average life Of a spark plug
two seasons. Some makes Of plug
