A good grade Of gasoline, one which
will vapOrize quickly, is perhaps C..
good as anything you might compound
The use OF mixtures Of ether and gas
oline or picric acid and gasoline viii
give a more forceful explosion, but
their use is not advised. If you dc
wish 10 use these chemicals the picric
acid should be mixed In the proper
tons of one ounce TO five gallons Of
gasoline and the ether three ounce 10
five gallons.
Are wide rings in a cylinder Of any
more advantage than narrow ones7
The wider the ring the greater the
fractional resistance. However, the
wide rings tend TO decrease the ex-
tent OF the leakage OF mixture and oil
past them.
Will you kindly explain the duties Of
tho eoll7
II Is taken that you mean a trans
former coil used In connection with a
battery or magnetic for ignition. Such
a coll is used TO raise the voltage of
the initial low tension current. A low
tension magnetic or storage battery
generates current Of such low pressure
that It will not jump the gap in the
spark plug. In order to make II jump
the gap the current Is passed through
q coil inside another coil, and while II
Is passing through II is suddenly In
terrupted. At the moment Of Interrupt
ton a high tension current Is induced
In the outside coil. This high tension
current is passed on to the spark plugs.
How often does Q magnetic have TO
DO remagnstized7
Much depends upon the conditions
under which the magnetic operates.
Once a year appears to be the average
period
Can you give me q formula for .
body poiish7
A very good polish for enameled body
parts Is made of the following ingre-
dents: Three ounces Of citronella, one
pint Of parafin oil. n gallon Of tur-
pentine and II and one-half ounces
Of oil of cedar. These should be mix
ed In the proportions named and ap-
piled to the parts with a cotton cloth.
After applying rub the parts well with
another clean cloth. This gives an ex-
cellent gloss, and the more 1t Is rubbed
the higher will be the polish.

1t makes no difference whether the
tow line In ten feet long or a hundred
feet long, for under the same condi-
lions Of grade, load, time, etc, the
power required for pulling will be the
same. II the rope Is very long and
drags On the ground the added friction
will require more power.
There 10 q knock in the engine Of my
car which can be heard only at Q
speed of 80 m. p. h. or above. This
knock resembles tho sound Of q ham,
mer beating upon hollow cast iron.
The position Of the spark lever has no
effect on IL. What would be the prob
able cause Of this7
This kind Of a knock Is most likely
due TO one OF two cause. Either you
have a loose connecting rod bearing
or n Of the main bearings needs ad-
Justment. There Is only one remedy
for the rod knocks, and that Is to re-
move whatever part Of the crank case
gives access to the bearings and to
properly adjust them. II shims are
placed between the cap and rod end
u t~hicknesses should be removed
as necessary to make up for the wear
that caused the looseness. The degree
to which b bearings have been tight
ened usually can be determined by
turning or rocking the crank shaft.
Tapping the cap with a hammer Is
sometimes q good indication to an ex.
perienced nan OF the tightness of the
bearings. 1t should be remembered
that there Is a medium between hay-
ing the bearings excessively tight and
TOO loose. The babbitt will soon burn
u In a bearing which Is too tightly
set up, or II 1t does not burn out It
VIII wear away rapidly. After the mo-
tor has had its bearings taken up and
adjusted 1t is most advisable to run II
under light load for several hours be-
fore using 1t on the road. This viii
serve to wear In the bearings, and dur
ing the limbering up process plenty of
oil should be supplied. About the
same procedure is required In taking
up any play or looseness In the main
bearings. Possibly the babbitt win
have 70 BE- worked down to a smooth
surface before replacing the caps.
