! have 1910 -- car The rear axle
J is a full floating type. having shafts
! with square ends which fit into the
( dlfferential and dogs in the wheel ends
! These shafts seem to be loose in the
! squares and cause considerable an
| noyance and rattle when the car IS
/ travelling over rough roads. While
/ these parts are simple in construction,
! nevertheless they are very expensive
/ / know that they should not be so
/ loose, but 1 do not feel that I can at
J ford TO buy new ones now. Is there
/ any way they can be treated to last
temporarily and yet be safe. Any ad-
vice along these lines will be appre-
ciated.-F. Badanes.
The ends of the axle shafts can be
heated and upset by any ordinary forge
man. When this is done it is an easy
matter to refit same to the squares
II is often necessary that they should
be case hardened. If the dogs or
flanges at the wheel ends are cOnsid-
erably worn it is often advisable to
have these built up by the welding
process and then refitted. In this
manner the parts can be fitted tight
Such repairs, if done properly, are
perfectly safe and reliable, and viii
often last as long as the new parts.

A wristpin bearing on my car has
burned out and I do not know how
10 III new one Should space be
left for play, or should it be fitted
ught as with main bearings?-R-
Pendleton.
Wristpin bearings should be fitted
with as much care as any other bear
ings, otherwise a bearing knock will
result.

I understand that a mixture Of two
gallons of gasoline with one ounce OF
10 an % eaN IL
increase in the motors power. Do
you know of any cases when this has
proved so?-Owner.
From a practical standpoint there
IS no reason why there should be any
increase in efficiency by using such
a combination. If you wish to in
crease the efficiency of the present
grade of gasoline there are a number
Of other chemicals which can be used !
TO a much greater advantage.

I got an unpleasant and quite un-
expected bath this morning while put |
ting denatured alcohol into the cylin- I
ders Of my car through the petcocks. =
The first three cylinders took the 1
liquid, but the fourth cylinder sDut- /
denatured alcohol. What would cause /
this TO happen?-M S. Goldman.
It is possible that you filled the com /
preston cup with the LIQUID and then 4
I
cylinder This particular cylinder was /
probably under compression at the !
time and naturally the alcohol was /
blown out by the force Of the compress
sion instead of entering the cylinder. {
On the other hand, if you injected the ]
alcohol into the climbers while they
were not II is possible that a piece !
OF lneandeseent carbon in the fourth /
cylinder ignited the charge.

1 am recOnstructing nv car of 1906 /
vintage, and wondered if I could in /
StaI a worm gear drive Please let /
me know how to go about this-M- /
P. Frank
It viii be impossible for you to in |
staI the worm drive construction in /
the old axle On account of the de- !
sign of the worm gear axle, it will be 4
necessary for you to install a com 1
plete unit This, of course. would be 4
rather expensive. The housing OF the /
bevel type differentiaI is constructed ]
entirely different from that of the /
worm gear type.

In four-cylinder motor does the pis- /
ton travel any distance before the ex-
pioslon occurs, or does the explosion /
take place simultaneously when the 1
spark IS made in the generator?-L !
There is more or less lag to the
spark. While this lag is infinitesimal,
nevertheless it can be measured. From
your question we presume you mean i
whether there is any lag to the burn
ing OF the gases. A volume of gas
when compressed burns very rapidly,
but its burning is not instantaneous
The gas begins to burn at the point
where the spark is led into the cylin-
der and from there spreads. The ra-
pldlIy with which II burns depends /
upon its destiny. A lean mixture burns
more rapidly. than a rich mixture. II
mere was no lag to the electrical cir
cunt and II the combustion Of the gases
W as instantaneous there would be |
little necessity for advance and retard /
acIlOn OF the spark The spark lag Is |
constant also that of the gases, but the
piston travel changes. As the revOIu-
lions per minute of the motor changes I
SO should the time of the spark change.
In snort, the spark should take place /
IN the cylinder at such a time so that /
the gases may become fully ignited and
exert the maximum expansive force on I
the piston Immediately after the dead
center point. If. the spark is intro
duced earlier than this, a knock will
result If later, loss of power and
overheating viii result.

NY car has acquired during the past
fortnight habit of coughing and
Jerking caused / believe, by miss
Ing of one or more of the four cylin-
ders, but as the plugs are new can

out the carbon deposits, readjusted and
filed the points on the master vibra-
tor, which / am using instead of the
vlbrators of the regular coil. Have
even tried out different vibrator and |
also a different carburetor. Some
times, after adjusting the vibrator
points or the needle valve to a diff
ferent adjustment the engine win
run fine for a short time. but soon
begins to cough again. occasionally al
most stopping It sounds as though it
did not receive the current and was
taking in all air.-Reader
1t appears that the missing is due ]
to a weak battery, in that a suffi-
GENTLY strong current is not supplied !
TO the coil Would suggest that you
test the battery. If you are using dry |
cells this may be a source of your !
trouble When standing for some time
these viii recuperate and serve well
temporarily A storage battery Is more J
reliable and should give better service
under constant use. It is also possible |
that the valves are sticking in the I
guides and do not seat properly. This
often happens when a poor grade of
oil is uEpd oil
