1.-Why will an engine be subject
to popping and splitting into the car
bureter when first started In winter?
An engine Is subject to popping,
splitting into the carbureter and UNI
even firing because OF the lack of
heat necessary to properly vaporize
the gasolene mixture from the car
bureter. Until the engine begins to-
| warm there Is more or less raw gas
olene admitted to the cylinders. It Is
hard to ignite and is slow burning
which explains the strange antics
thru which the engine goes upon
starting. Continuous popping even
after the engine Is warm indicates
too weak a mixture. In which case
more gasolene should be fed to the
cylinders by adjusting the carburet-
err. le
2.-What should be done while the
engine Is being cranked in winter. and
especially II the storage battery is
weak, to aid starting7 s-
To aid starting the engine after
has been standing exposed to the cold
for a period always disengage the
clutch while the engine Is being
cranked. This will allow the engine
only to revolve with the starter, in
stead OF most Of the transmission,
which latter would be the case II the
clutch were fully engaged. In cold
weather the lubricant in the trans
mission gear case is considerably
more solid than in summer and re-
quires more energy from the storage
battery to move the parts in the lub-
ricant. II battery is weak 1t will be
about all it can do to turn over both
engine and transmission when cold.
3.-Are carbide gas generators sub
ject to freezing In winter? What Is
preventive3
A carbide gas generator with water
drip will freeze in cold weather. The
remedy Is to use q half alcohol and
half water mixture In the water tank
to prevent freezing.
What is a quick temporary re-
pair for small leak in a gasolene
tank?
A small leak In q gasolene tank
can be temporarily repaired by filing
the leak with soap. A leaky gasolene
tap In the tank or line can be repaired
by grinding in the tap with a very
fine grinding compound. Sometimes
| merely tightening lock nut at the
tap will stop the leak.
5.-Why Is It advisable to clean
the oil pan Of the engine more often
In winter than in summer?
The oil pan of an engine should
be cleaned more often in winter than
| in summer because there Is more gas
olene in raw state drawn from the
combustion chamber past the rings
into the crankcase, especially when
the engine Is hrst started and when
| the full charge admitted to the CYL
| tnders is not combusted.
6.-What Is q common cause of
| slipping brakes?
A common cause Of slipping brakes
| is that Of lubricant working out of the
| axle ends and on brake bands. Wear
OF the parts designed to retain the
Gil or grease may be the trouble, al
| tho az rule leaking is the result of
too light lubricant or too much
being carried in the rear axle hous-
| ing.
| 7.-What are some causes Of dim
lights, even when the engine is in
operation?
When the engine is in operation,
dim lights or no light at all may be
due to broken wires, loose connections
at lamps, generator or battery, poor
or loose contact at generator ter
minals or brush connections, loose
connections at switch. burned out
bulbs or bulbs not making contact
with lamp sockets or loose lamp
socket terminals. These troubles are
to be considered providing, Of course,
that the battery and generator are
producing sufficient current.
8.-What conditions are necessary
for the engine to have an even pull
with no missing at slow speed?
To have an even pulling engine
with no missing at slow speed there
should be good compression, which
means tight rings and valves. The
valves must have the proper clear
ance, spark plug electrodes set at
proper distance apart and the plug
itself in good condition. Also the
| carbureter must be set carefully so
the mixture will not be too rich. The
spark coil cannot be short circuited,
as it will sometimes fire correctly on
high speed but not at slow speed. The
