valuable columns of answers to au-
Z tomobile problems. In going up a
short hill of moderate grade my
car seems TO lose power and can
I hardly make hills which other cars
make without any trouble on high
gear. l usually have 10 cut down TO
/ second gear. Do you think il is due
TO the piston rings being worn or do
the valves need grinding? Please
let me know. also, if the steel-stud-
ded puncture- proof shoes are ser
viceable or if they are a detriment to
the tire? Thanking you in advance,

There are so many reasons why
IAN engine should lose speed on a
hill that further information must
be had before a complete answer
can be made. Carburetor. loss of
compression. ignition troubles. car
bon, lack Of fabrication, all enter
into the problem. If spark plugs
are badly carbonized, the carbon
should be removed from cylinders.
II engine shows loss of compression
when cranked by hand. valves
should be ground. Worn rings will
cause loss of compression. which can
only be remedied by replacing the
rings. Cranking by hand will also
test fabrication. Steam at radiator
will show Overheating. A very lean
mixture will cause popping back at
carburetor, and rich mixture will
have a pungent Odor. A weak bat
terry will give a weak spark. Dis
connect one spark plug wire and
hold one-quarter inch from head of
plug while engine is running a
good fat spark should jump. BY
trying out above list you may get
an idea of where the trouble is To-
Gated. The steel-studded tires are
good. but have tendency to loosen
up and separate. This Is somewhat
offset by the fact that they are more
or less free from punctures.

Times Manufacturer feature very
conspicuOusly the worm-gear steer
ing wheel on their respective makes
of cars as being irreversible. Then,
if this is true, how do you account
for being able to crank an engine
with the momentum of car or
truck when it has a worm gear in
the differential? Why wouldn't this
also be reversible? Would like
very much TO have an answer to
this question through the columns
of your paper. Il. "A. L.
1t is very evident that the worm
drive is not irreversible. but only
partly so We assume that you

Motoring Department. The News
Times.-The valves in my 1916 |
Dodge make a clicking noise What |
is the cause and what is the remedy? |
Would il injure the motor to con-
tinue 20 run in that condition? Is
radiator cement liable TO clog up |
the radiator? Thanking YOU.
r. o. J.
Evidently the valve tappets are
loose and neel adjusting. If con-
tinued the spaces will grow larger |
and the motor will begin to lose
power. They should be adjusted 10
the thickness OF a piece of writing
paper. and the adjustments so firm
" secured that they will not readily |
loosen. Radiator cement has a
slight tendency 20 clog a cellular
lar radiator, but not a tubular.

Goes no one invent
spring tire 10 take the place OF the /
present tire. Such a one would be
puncture- proof and ought not 70 be
very expensive. Is the idea feasible
or has il already been tried out?
J. X. L.
Many devices OF the kind you
mention have Teen patented but
none have attained any success. As
a rule they are very heavy and none
OF them give the springy effect OF
com pressed air. Some such spring
devices are used on a few trucks in
with a solid rubber tire.
but no device has yet been found
for use on pleasure cars.
