In a gasoline engine, is any more
power obtained from the explosion by
! having the spark plug directly in front
| of the piston rather than at ono side
| IN boss or recess?
There are two theories relative to the
location of the spark plug in recess
| within the cylinder. One is that by
| having the spark plug in such recess
| a squirt Of fame enters the combustion
| space from the recess and as result
| quickly tgnites the charge. Another
theory is that by having the spark plug
directly in the center of the conbus-
! 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 it gives the fame
a chance to propagate itself In all d.
rections. Practice favors plug which
merely has its points projecting into
the combustion space.
| Why do have difficulty in starting
on my r1aanoto in damp weather.
The difficulty you have in starting In
wet weather is probably due to nois-
ture short circuiting some of the wires.
Inspect the wires carefully for any
points that might be affected by mos
ture and see that all the insulation is
in good condition.
How will burn the carbon out of
tho cylinders of my engine with oxygen
acetylene fiames2
An oxygen.acetyiene fame is never
used for burning carbon out OF cylin-
ders Acetylene is OF no use for this
purpose, but by employing oxygen
! alone very satisfactory job can be
done. The oxygen is used because It
supports combustion five times as read
lily rs mir docs, 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 very vigorous
manner. In fact, sometimes the car
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 nlarrinG of the var
nish by the-sparlls. The oxygen is sup
piled from n tank in which 1T is stored
under very high pressure, and. as the
pressure, ut the delivery nozzle OF the
outfit must be small, reducing valve
must be Used to bring the pressure
down to q reasonable amount There
fore between the tank and the tube
TINT carries the gas to the cylinders
there is a reducing valve that auto
rnatically lowers the pressure. A gauge
is generally fitted TO the tank to indi-
cate how much rA there is in 1t. be

have leather faced cone clutch
and wish TO Put on a new one. want
TO know tho best kind of leather can
get for tho 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
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. If
an asbestos fabric is used, care should
be taken to obtain piece that is
made for the size of cone you have.
Unlike leather, strips of this material
to fit cannot be cut from large piece
of fabric. The thickness of the facing
is 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-
err and cut your own facing you should
remove the old clutch leather and use
it for a pattern. Before applying the
leather it Is well to soak 1t In heats
foot oil to soften 1t. 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 q manner that
It slips down over the smaller end Of
the cone. Then pull it tight and rivet
the other end. Now push the leather
up In place all around and it should be
tight and unwrinkled.
The same advice applies to putting
on an asbestos fabric, but there Is less
danger of the facing wrinkling.
Will you explain fully the method Of
fitting and tapping in new piston ringer
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 it in and out IN
