Where would you consider the proper
place for q gasoline tank2


placed under the cOwl the gasoline can
flow by gravity to the carburetor, yet
the carburetOr does not need to be
placed as low as when the tank is I'M
der the seat. BY locating the carbu-
rotor higher, it is more accessible and
the intake pipe is shortened, giving bet
ter carburetiOn. The gasoline is warm
ed by the heat of the motor so that
in cold weather, at least; carburetiOn
Is facilitated.
The under seat location of the tank
also allows fuel feed by the simple
gravity method, but there is danger of
the flow stopping when climbing a
steep hill. When the tank Is being
filed the passengers in the front must
be disturbed.
Putting the tank at the rear utilities
otherwise waste space and allows the
space under the front seat and under
the cowl to be used for other purposes.
There is a slight objection to this loca-
ton, however, because the gasoline
must be fed to the carburetor either by
pressure or the vacuum system. This
means slight amount of complication.
but 1t is not serious, as is indicated by
the fact that the majority of cars now
in use one or the other of these sys-
TENS
A very large percentage of the cars
put on the market in the past year or
two use the vacuum system of fuel
feed In which the main gasoline tank
is located at the rear of the car, while
small auxiliary tank is placed on the
dash, usually inside the hood, to give
gravity feed to the carburetor
On level road or slight ascent my
car runs we'll, but on sleeper grades il
misses, chokes and back fires. had
new rings put in and the compression
seems good. What is the cause2
From the information given it would
appear that the gasoline line between
the carburetOr and the tank is slightly
clogged. The gasoline flows through
rapidly enough to feed the car under
conditions obtained on the level road
or on slight ascent, but on sleeper
grades the feed is not fast enough to
do the work. II you remove the pipe
connecting the tank and carburetor and
clean thoroughly it will probably end
the trouble.
My car will not hold compression
very we'll. put in two new rings, and
think they do not fit we'll enough as
yet, as the car has only been run about
thirty miles since. The compression
was fairly good with the old rings, but
thought ! could improve il with new
ones. Is there any way to make them
fit moro tightly by using grinding COM
pound?
In order to get the new rings to fit
we'll at once they should be Tapped in
by means Of grinding compound
The cylinder is put on a bench and
the piston worked out and in with a
sort Of irregular turning movement
similar to that given in grinding a
valve This work can be done by an
amateur, but should not be attempted
without first having observed carefully
how 1t is done, because 1t is easy to
spoil the piston and cylinder by I'M
equal abrasion. The probabilities are
that the new ring will wear in and the
compression will be tighter after you
have run another two or three hum
bred miles. and altogether it would
probably be better for you to wait and
see that this does not happen unless
you can get the services of an expert
in tapping in the ring.
When the spark on my car is retard-
ed IL misses considerably. Is this
sign that the magnetic is weak?
No. Retard and advance simply re-
fer to time of spark occurrence. The
spark is just as strong on retard as 1t
is on advance. When the spark Is re-
tarded 1t means that 1t occurs when
the piston is going downward, and
when 1t is advanced 1t occurs when
the piston has not yet reached dead
center.
Should the valve spring be a stiff one
under small compression or rimble
spring under heavy compression to give
best results2
The stiffiSss of the spring will be
found only by experiment. AS the pis-
ton descends II creates a vacuum In the
cylinder, thus allowing the pressure Of
the atmosphere to open the valve. II
the piston suction Is poor, then the
difference in pressure between the bot
tom and the top of the valve will not
be so great, and hence the valve Will
have tendency to remain shut. How
ever. II piston has good suction the
valve win open without difficulty. You
will have to try your particular mo-
tor and valves in order to get the best
results.
Please explain the proper way Of
overhauiina car.
In good repair shops and service sta
tons the entire car Is disassembled,
the parts Inspected, worn ones re-
placed and the car then reassembled.
However. It Is often found that GER
tain parts do not require attention.
For example. the repair man may find
that the differenhal and gearset are In
good shape and viii not 20 TO the tr0n-
Bile Of taking them apart
