Answers to Last Weeks Questions.
1. Just how should spark and gas
controls be manipulated to carry a car
up hill on high gear? This question
has been asked by many drivers. NOT
every one beginner, and undoubtedly
occurred to them after they had failed
to negotiate certain stubborn grades.
Perhaps their engines had power
enough. failure to climb the hill possi-
bly, being the result of incorrect use of
the aforementioned controls. The
success of hill climbing depends upon
the drivers confidence in his engines
ability, plus a good running start be-
fore the hill is attempted. Before
starting to climb speed up the engine.
advancing the spark fully at the same
time. A good rate Of speed should be
attained, and when the foot of the hill
Is reached set the hand-throttle control
at the steering wheel to about two
thirds or more advanced. keeping the
foot of the accelerator. When part of
the hill has been travelled retard the
spark to about three-fourths open or
little less and keep 1t there. With
controls in this position the engine will
do its best without being overtaxed or
impossible to climb every hill on high
gear. but If the hill is too great the
limitations of power will soon be man.
ifested by steady reduction of car
and engine speed and pounding and

drivers fail to clear an average sized
hill with their cars in high gear is be-
cause they open the throttle too wide

car starts up the grade. They also

2. Spark coil trouble is sometimes
| caused by carelessness in washing
; the car. II the coil was soaked with
| water 1t would not function properly
| causing misfiring. The remedy is to
remove the coil and heat slowly un-
! til dry. Care must be used that the
| coil does not become too warm, as it
| would be ruined by the insulation
t, within becoming soft. The drying
process requires from half to two
days at even heat.
g. You can tell If your headlight
or spotlight bulbs are in focus or
| not in focus by noting the direction
! of the beams from the rehectors. II
the bulb of lamp Is to the left of
the refiector's focal center the beam
will be thrown to the right. and II
bulb is to the right the beam will
be to the left. The same rule ap-
plies to the bulb being above or be-
low the center Of the reflector.
4. When nut cannot be removed
with an ordinary wrench and any
effort to remove it would merely re-
suit in. rounding the corners. try
heating a wrench which will fit.
placing it on the nut and allowing
1t to remain for a period. The nut
should then be removable with no
trouble. as the heat will expand it
before the bolt to which it is Sc
cured is warmed.
5. To remove a wheel. tightly secured
to its axle without the aid of wheel
puller. remove the hub cap. place a
piece Of wood. with one end against the
