Would a kerosene carburetOr with
hot water jacket around the 1loar
chamber work all right, the tempera-
ture being $50 degrees Fahrenheit
Economy.
Your carburetor would work after
the engine had become sufficiently
heated, but you would experience much
trouble in loss of power, and also in
starting the motor when cold. Kero-
Sene does not vapOrize readily. To mix
the oil, vapor, and air at the atmOs-
pheric pressure requires a temperature
Of approximately 290 degrees Fahren-
heit- This operation reduces the Spe-
Cific gravity OF the charge, and the
result is that a given volume viii con-
tain less thermal units than when in
trOduced at atmospheric pressure.

It is not necessary for the motor to
smoke in such a manner as TO be
a public nuisance You can with safety
reduce the oil supply If the motor is in
good condition. When the motor runs
at normal speed it should not smoke
When accelerated 1t should smoke
little. If you permit the engine to
smoke excessively you will soon be

smoky exhaust is the result of. i'm
perfect combustion in the cylinder and
this in turn causes foul motor.

In time an accumulation Of carbon

A condenser Of proper capacity

It must be remembered that in starting

importance to those who either have to
or want to do their own tinkering. One
OF them is to refrain from putting ACID

By constant use the bearings Of the
clutch collar and the primary gear
shaft Of a car are apt to become slight
" loose and so permit the clutch and
gear shaft to spin a good deal when
changing gears: the result is a dis
agreeable clashing unless the parts are
given time to slow down The simplest
remedy is to tighten up the clutch
collar bearing, and so provide a slight
braking effect which will prevent
spinning.
A possible cause for the breakage of
incandescent lamp filaments in either
inside or outside automobile lamps is
1ooseness Of the bulbs in their sockets.
The rafting OF the lamps is accom-
panied by a series Of sharp little raps,
filaments. It often is possible for such
looseness to exist without interrupting
the flow or current
