During the winter months tires need
careful attention. Aside from underin-
| fation, small cuts in the tires are very
injurious Moisture and grit in the Sc
cuts will loosen the fabric and cause
rapid depreciation and eventually a
blowout. All small cuts should receive
prompt attention and treatment. BY do
ing this the life Of the tire can be pro-
longed fully 30 per cent.
1t is well to remember that at low
temperatures the storage battery should
not be left standing in n discharged con-
dition. When charged the electrolyte
contains the acid which prevents freez-
ing. When discharged the electrolyte Is
not sufficiently strong to prevent freez-
ing.
II the motor on cranking will run for
a half minute and then stop, look to the
gasoline feed line. A stoppage in the
pipe will lessen the flow OF gasoline so
that the float chamber Of the carbureter
fills slower than the motor consumes the
fuel. As a result the motor stops until
the carbureter fills again. The remedy
is obviously to clean out the pipe An
other cause may be a sticking float in the
carbureter. II the float is stuclin a
high position the flow OF gasoline will be
curtailed or even stopped.
II the motor shows a tendency to miss
and stop when switched to the magnetic.
look to the gaps of the spark plugs. For
most magnetos the points OF the plugs
should not be separated over lie inch,
and a longer space will result in the
current failing to jump.
Properly designed mufflers such as arc
fitted to most cars nowadays create lit
tie or no back pressure and absorb hard
ly any power. This means that opening
the mufYler cut-out does not increase the
power. The only proper use Of the cut
out Is to listen to the sound OF the ex-
plosion when working on the motor. At
night. the character Of the mixture and
its combustion may also be judged by
watching the cut-out. IL 1t be close
enough to the motor to allow flames to
escape. A yellowish flame indicates that
the mixture has too much air. while

Gates too much gasoline. A properly pro-
portioned mixture will show a blue
flame such as is given by a Bunscn bur-
ner.
Do not use fiber washers in the gaso-
line line, as the gasoline dissolves them.
forming a deposit which may clog the
pipe or the carbureter. Use soft lead
washers In reassemblIng the pipes after
taking them apart for cleaning
Quite often there wifi be an unnoticed
drip Of gasoline for few minutes from
the carbureter after the engine has stop
ped. This Is not only a waste OF fuel, !
but 1t Is dangerous from the risk of fire. |
Usually this condition Is due to the float
