the carburetor does not need to be

rotor higher, II 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 utilizes
otherwise waste space and allows the
space under the front seat and under
the cowl t. be used for other purposes
There Is n 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 n slight amount Of complication,

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 ut the rear Of the car, while
q small auxiliary tank Is placed on the
dash. usually inside the hood, to give
gravity feed to the carburetor.
On a level road or slight ascent my
car runs we'll, but on sleeper grades it

now rings put in and the compression
seems good. What is tho cause7
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 a slight ascent, but on sleeper
grades the feed Is not fast enough to
do the work. If you remove the pipe
connecting the tank and carburetor and
clean thoroughly it will probably end
the trouble.

ones. Is there any way to make them
fit moro tightly by using grinding COM

In order to get the new rings to fit
well at once they should be Tapped in
by means Of a 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 a be done by an
amateur, but should not be attempted
without first having observed carefully
how 1t Is done, because it is easy to
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 hun
dred 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 It misses considerably. Is this a
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 it
Is On advance. When the spark is re-
tarded it means that 1t occur when
the piston is going downward, and
when it is advanced it occurs when
the piston has not yet reached dead
center.
Should the valve spring be a stiff one
under small compression or a nimble
spring under heavy compression to give
best results7
The stiffness Of the spring will be
found only by experiment. AS the pis-
ton descends 1t creates a 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 a tendency to remain shut. How
ever, If a piston has good suction the
valve will open without difficulty. You
will have to try your particular mo-
tor and valves In order to get the best
results.
