Answers to Last Weeks Questions.
Warm weather has a very decld-
ed effect on a carburetor. Air and
heat are necessary for the carburetor
properly to vaporize the gasoline.
When the air is warm the vaporiza-
ton takes place more quickly and
with more efficiency. thus allowing
the supply of gasoline to be cut down
This is called a '1eaner mixture. In

motor as richer mixture in cold
weather.

suddenly stops. any of the following

cylinder: Z. gasoline supply exhausted.
"a common cause of misfring is

"A motor can be prevented from
overheating when driving in low gear
for long time by reducing the gaso-
line mixture. Reduce the carburetor
mixture as lean as is possible for
smooth running in low gear. AS
richer fuel mixture will cause more
heat. the lean mixture will tend to
overcome overheating. 1t also is
more possible to drive a car with
leaner mixture on low gear than on
high.

Answers to Above Questions.
1. Celluloid automobile windows can

and is not as difficult a job as may be
imagined. Buy sheet celluloid and some
celluloid cement at an auto supply store.
Cut the celluloid the correct size and
cement in place. The use of cement
makes it unnecessary to sew it on. Rips
or breaks can be repaired by cementing
a patch on. These patches will give
good service for a long time.
2. In cleaning new car the following
things should be observed: Use cold wa
ter, which will help set the varnish;
never play swift stream of water di-
rectly on the body, as the luster will be
ruined by the force of the stream work
ing particles of dust into the finish; do
not wash the hood when it is warm, as
this. too. will affect the luster: never
use soap except for the removal Of oil
or grease from the surface; to remove
the grease from wheels or tenders use
a soft soap made of pure vegetable
oils with no acids or grit, dissolve it in
lukeWarm water and apply the sudS and
rinse in clear water.
3. After an inner tube has been in
serted in a casing it is important, before
mounting the casing on the rim. to slide
the hand around between the inner sur
face Of the casing and the tube to make
sure that there are no wrinkles in the
tube. A good way to avoid wrinkles is
to slightly initiate the tube before in
sorting 1t in the casing.
4. An emergency repair for broken
spring hanger is to wire the spring to
the frame Of the car. Jack up the for
ward end of the spring. SO that all ten
sion will be removed while it is being
wired. If the car is run slowly the
spring will hold temporarily
5. Some of the new modern racing
cars have motors of eight cylinders
mounted in one line. This differs from
the usual stock motor of the same num-
Der OF cylinders. in that most of them
are OF the V-type, four cylinders to a
side.
