lacked up and then a mark put on the
Universal. so that it can be watched,
and the rear wheel is then turned
around, is the gear ratio given the cor
rect ratio? In other words, If a car is
ceared say, four to one and the wheel
is turned around once, will the shaft
turn four times, or will the fact that
the one GEAR in the differential is not
moving cause a drag and therefore give
a wrong ratio?
The ratio with one wheel lacked up
will not be the correct ratio because
there are two reductions to be consid-
cred. When turning the wheel the
first reduction is between the shaft
bevel and the spider bevels and the
second between the ring gear and the
driving pinion. The correct ratio can
be obtained by lacking up both wheels
and turning both Of them. Why not
try this on your W car? Jack up n
wheel, place the gear shift lever In d.
rect and then turn the one wheel
which has been lacked up.
When going up a grade slowly on
high gear my engine makes a dull,
humping sound. The carburetor is
set low, requiring a long manifold. Do
you think this sound is due to conden-
sation in the manifold | was told that
the trouble might be remedied by hav-
ina a new exhaust manifold made d.
vided, a separate exhaust for each. pair
of cylinders, for the trouble might be
that the explosions overlap and the en-
CINE not scavenge properly.
The knock is either q spark knock
or q gas knock. If it is a spark knock
you should retard the ignition somc-
what when in heavy pulling, such as
up grade work. If it is a gas knock try
closing the throttle a little more when
pulling up a hill. Open the throttle
gradually as the load on the motor be-
comes heavier. 1t is not likely that a
double exhaust manifold would benefit
you. Do not try to negotiate steep
hills on high gear. Give the motor a
chance by dropping to a lower gear
when the pull is too much for direct
drive. If it were true that the cylin-
ders are not ~scavenged properly you
would notice 1t at other times than
when climbing hills.
How can rim cutting be prevented?
am having great trouble with casing
rim cutting on my car. use sixty
pounds in 80 by 3Na inch tires and sew
enty pounds in 81 by a inch.
Rim cutting is due to under imitation.
Get a new pressure gauge that you are
sure is correct. Probably your gauge
is reading too high, making it appear
that the tires are properly inflated
when they are not.
What may be the injury caused by
using o~vertension on clutch springs?
Is there an excessive pressure brought
to bear on the crank shaft bearing by
using tight clutch springs?
If the clutch is properly designed
with a thrust bearing there will be nc
pressure brought to bear upon the
crank shaft bearing by the clutch
springs. The big objection to too tight
an adjustment ON the clutch spring is
that 1t will make the clutch grab in
stead of giving it a gradual engage
ment.
My car works nicely running below
fifteen miles an hour, but over that
speed it misfires and spits back in the
carbureter. 1t will do the same on
heavy pulls, on hills and on sudden
opening of the throttle above a certain
point. Carburetor adjusting does not
do any good. | have put in new piston
rings and new brushes in distributor
the magnetic or the carburetor?
1t is possible that your trouble is
caused by a poor adjustment of the in
terrupter of the magnetic. This inter
rupter is used for both battery and
magnetic circuits, and should the points
be too far apart on the break or too
close, perhaps, there may be backfir-
ing and misfiring. The points should
be about .015 inch apart when fully
open. Sometimes a fine adjustment
will show better results. You will have
to try various positions. After ADJUST
ing the points place a drop of kerosene
upon them. Granting that the ignition
system is properly timed and that the
carburetor is adjusted correctly, you
might look to poor valve timing as the
cause of your trouble. Carbon depos-
its in the cylinders will often cause
the condition you mention. If you
wish to check up Oh the carburetor ad-
Justment push the auxiliary valve open
while the motor is operating with the
throttle open more than one-half. This
al be done with a pencil or screw
driver. Should the misfiring stop when
the air valve is pushed open then you
will have to compress the air valve
spring. If the misfiring and backfring
become worse, then the spring should
be stretched. There should be no air
leaks around the valve caps, the spark
plugs, the inlet manifold, printing,
cocks, etc.
