theory Is that by having the spark plug
directly in the center Of the combus-
ton. or. that is, SO that the spark plug
points project outward into the com
bustion space itself, the gas Is quick
ly exploded because 1t gives the flame
a chance to propagate itself in all di-
rections Practice favors n plug which
merely has its points projecting into
the combustion space.
Why do | have difficulty in starting
on my magnetic in damp weather?
The difficulty you have in starting in
wet weather Is probably due TO mois-
ture short circuitins some Of the wires.
Inspect the wires carefully for any
/ points that might be affected by mois-
ture and see that all the insulation is
IN good condition.
How will | burn the carbon out Of
the cylinders of my engine with oxygen
acetyIene fiames7
An oxygen-acetylene flame is never
used for burning carbon out of cylin-
| ders. Acetylene is of no use for this
purpose, but by employing oxygen
alone n very satisfactory job can be
, done The oxygen is used because II
supports combustion five times as read
lily as air does, and therefore. once the
carbon is ignited, it will burn rapidly,
! although it will not burn ut all in air.
In cleaning carbon from the cylinders
in this manner the first thing to do is
to remove the valve caps; then the cyl
! inder is filed with oxygen. A small
! piece of burning waste is then dropped
into the cylinder, and combustion i'm
mediately begins in Il very vigorous
manner. In fact, sometimes the car
I bon is consumed SO rapidly that sparks
will fly out of the valve openings, and
| for this reason it may be advisable to
cover the front part of the car with
| damp cloths to catch these sparks.
From this it must not be thought that
there is any danger of setting the car
afire. because the continued use Of OK
ygen has demonstrated that there is no
possibility of this occurring. If damp
| cloths are not used the most that will
| happen is slight marring of the var
| nish by the sparks. The oxygen is sup
| piled from tank in which it Is stored
under very high pressure, and. as the
| pressure at the delivery nozzle Of the
outfit must be small, reducing valve
must be used to bring the pressure
| down to reasonable amount. There
| fore between the tank and the tube
| that carries the gas to the cylinders
there is a reducing valve that auto
matically lowers the pressure. A gauge
| is generally fitted to the tank to indi-
| cate how much gas there is in 1t, be-
cause as the quantity becomes smaller
the pressure drops.
I have a leather faced cone clutch
and wish to put on new one. want
to know the best kind of leather | can
get for the purpose; also how to put it
| on. Would asbestos be better than
leather?
Either leather or an asbestos fabric
may be used with satisfaction. If you
use leather you should obtain friction
leather. which is made for this pur-
| pose.
In ordering the facing, the diameters
OF the two edges of the cone and the
width of the cone should be given. III
an asbestos fabric is used, care should
be taken to obtain Il piece that Is
made for the size of cone you have.
| Unlike leather. strips of this material
! to fit cannot be cut from a large piece
OF fabric. The thickness Of the facing
il important because too thick facing
will prevent the cone from properly
entering the fywheel. One-quarter
inch is an average value.
| If you desire TO buy piece of leath
er and cut your own facing you should
remove the old clutch leather and use
1t for a pattern. Before applying the
leather it is well to soak it In a meats
foot oil to soften it, Care should be
taken to cut the leather TO the correct
length. The best way Is to first rivet
one end and then wrap the leather
around the cone in such a manner that
IL slips down over the smaller end Of
the cone. Then pull it tight and rivet
the other end. Now push the leather
10 in place all around and 1t should be
| tight and unwrinkled.
The same advice applies 10 putting
| on an asbestos fabric, but there Is less
Danger of the facing wrinkling
viii you explain fully the method of
fitting and tapping in new piston rinssY
place the cylinders on the bench and
apply some ground glass and oil to the
interior The ground glass should be
very fine. Then place the piston in
the cylinder and work 1t In and out un-
til the rings are well polished and fit
tightly. Tapping is an operation which
requires an experienced man. Further
