Asbestss washers.
Spare asbestos washers should al
ways be treated before being placed
among the spares In the car. A six
hours soaking in olive oil. followed
by a draining and brief drying and
a nnal rubbing with fine black lead
will give a good tight washer that

Carbureter Fire.
In the rare cases where the car
bureter catches fire because of a back
fire the connagra ton may be extin-
guished by turning on the gasoline
and then racing the engine. In this
way the engine sucks the faring liquid
out of the carbureter and so the fire
dies out OF itself.
Garage Floor Space.
In planning the home garage, re-
member that for a single car the
minimum floor space will be twelve

allow room for either a work bench
or for storage space. they are simply
the irreducible minimum for the man
who intends to take care of his car.
To StraIghten Front Axle.
A method of restoring a front axle
which has been bent is TO take two
lengths OF AKA inch joist just long
enough to reach from the upper side
Of the axle outside each spring plate
to cross timber of the ceiling or
roof of the garage. Then IL a jack
is placed beneath the axle at the bend

means of It to force the axle back
into shape.
OIL Filter.
As a means OF separating dirt. metal
metal dust. etc. from used oil: the
hitter which may be mace in the fol-
lowing manner will be found very
efhcient: Fasten a piece of muslin
or cotton cloth to a metal or wooden

Odometer Accuracy.
One frequently hears the suggestion
that a change Of tire size makes a
very serious difference in the accu-
racy OF the speedometer and more
particularly of that shown by the
odometer. AS a matter OF fact, there
is difference, but it amounts to very
little when short distances are con-
sidered- For instance. a difference O:
half an inch in diameter in a thirty
four inch tire makes a difference in
odemeter reading of eighty feet TO the
| mile. However. when a permanent
change in tire size is made. IL is i'm
portant to have the recording instru-
ments adjusted TO meet it,
Strength Of Valve Springs.
Valve springs that are too stir ma v
! close the valves with so much force
that the heads may be broken from
the stems. or they may break the
stems at the key slots On the other
hand valve springs that are too weak
I TO hold the valves on the cams will
make the engine weak at high speed
and produce chattering owing to be-
lated seating of the valves. In this
connection il must be remembered
that too stiff valve stems. even N
they do not injure the valve seats by
constant hammering. are consuming
power that could be better used else
