It's never too late to mend, or to be
more specific, to signal. Recently o
woman started to turn left and forgot
to signal. The day-dreaming chap be-

delayed signal just in time to. warn a

her forethought, delayed as 1t was.
Sometimes the gear shift lever will
slip back into neutral from high when
the car Is going down hill. It Is un-
lawful in many States to coast IN neu-
trail and. of course, it is dangerous. But
to get back to high without stopping
requires special knowledge.
The trick Is to race the engine while
the clutch pedal still IS In the up po-
sition. Shift quickly to high as you

am frequently asked by women who
earnestly want to get at the heart OF

crank the power plant before 1t gets

start as soon as the ignition switch Is
| turned to the ION" position?
There are four outstanding reasons
| for this, and perhaps the best way 70
explain them is to start with the 1act
that the automobile engine does not
run on raw gasoline. 1t first must De
| vaporized. and to do this we must
atomize it with air. Since the auto
mobile carburetor isn't equipped with
an external air pump, or atomizer. 1t Is
necessary to resort to internal air sue
ton to break up fuel into spray. The
pistons, moving up and down IN. thelr
cylinders, furnish such suction.
To vaporize the spray, therefore, we
must crank the engine over to get the
pistons moving. This also operates the
valves that open ports through which
the suction and sprayed vapor pass.
The final step is to compress the
vapor so that 1t will fire with enough
force to drive down the pistons that
have drawn it in and compressed It
When we have done all this the engine
is ready to run, and not a moment
sooner.
In the process described above the
choke plays a very important role
When you pull the choke button out all
the air is blocked off from the intake
of the carburetor so that the pistons
suck fuel alone This serves to break
up the fuel into small molecules. or
what is known as wet" spray. With.
out air, however, this spray would not
ignite in the cylinders, so the choke
