I am driving a --s and am having
trouble with the two front cylinders
missing on low, running very rough
Not knocking, but running as if some
bearing were loose and rafting
around The noise seems TO be in the
crank case, but 1 have had the lower
half taken down and all main and con-
Meeting rod bearings drawn up snug
There is no movement when an iron
bar is put under the flyWheel and INT
ed up and down
The only thing left to do is to take
off the front two cylinders and look
for broken or weak springs or badly
find the two cylinders are %0rn out OF
true what can I do with the least ex-
pense to restore compression?
do not care TO so to the expense OF
having cylinders regrOund and plsJonS
fitted, neither do 1 care to buy new
cylinders and pistons, etc. VIII the fit
ting of stiff new rings upper and
lower restore the compression?
This engine is fitted with a
carbureter, which gives plenty Of gas
and which has been recently cleaned
and adjusted.-James Perrin.
Possibly the wrist pin bearings are
loose and need adjusting If you have
no compression in the two forward
cylinders IL is doubtful whether new
rings viii remedy the trouble. II the
two rear cylinders are not worn &c
centric there IS no reason why the two
forward cylinders should be- It IS pos
sible the cylinders have been scored by
loose wrist pins As stated previously,
new piston rings properly fitted viii
help to restore compression, but II the
cylinders are excessively worn or
scored the compression viii not be
benefited materially. 1t seems adv1s-
able to remove the cylinders for in

When starting the motor after IT has
been at rest for a day or so, we have
to crank several times before it viii
continue to run 1t fires several times,
then dies. 1t runs fine after warming
ur but takes considerable cOaxing TO
induce IL TO continue long enough to
warm uD. Can you suSgesu remedy?
"A y, Hartcoer
This trouble usually lies in the low
speed adjustment of the carbureter.
All motors are difficult to start when
cold, due TO the improper VaporizatiOn
desired adJus tnelt on the carbureters
it seems most advisable to prime the I
cylinders before starting under such
conditions

What should be the condition of the
compression chamber in a motor when
working to best adTantage2 Should
the piston head and compression space
be dry and sOOtyi or in an oily con-
diuon George COnover.
The condition Of the combustion
chamber should be as clean as posi-
bic. An oily condition indicates too
much oil and imperfect combustion
The cylinder will necessarily be sOoty
on account of the products Of COM
bustiOn- While there should be no
carbon residue, nevertheless it is i'm
possible to realize such ideal cOndi-
lions.

How long or how many miles should
a motor car be run before refiIling the /
transmission and differentiaI cases
with grease2-M- r. T.
There is no fixed rule as to when
transmissiOns and differentials should
be filled with grease. 1t depends I
greatly upon how these units are con-
structed and also the grades of lubri-
cants used. On the average car 1t is (
customary to inspect these units fire.
quently in order to learn whether they !
are receiving proper fabrication or I
not. Ordinarily the differential I
should be refiued about every 5000 !
miles The transmission usually re- Z
quires twice as much attention

In descending q long hill, should one 4
use both the foot and emergency 4
brake or just the foot brake?-Ama- !
teur.
In descending a hill the driver 4
usually coasts, controlling the speed !
Of the car by the service brakes It j
is good practice to equalize the wear J
on each brake. The service brake is 4
the one most used, therefore, when
opportunity offers it would seem ad- +
yisable to use the emergency brake I
The term emergency does not specif-
lcauy apply to cases OF emergency. but I
is rather an extra set Of brakes for I
use should the service brake fail to
act at any time. The driver must ex-
ercise judgment in the use Of his
brakes. and should keep both in equal
" good condition. The main Objec-
tiOn is that when it is set there is no
great amount of elasticity to it. In
going down a hill with the emer-
Eency brakes set one often encount-
ers water ridges, which are apt to
