Answer. to Last Weeks Questions.

I The spark lever is for controlling
the ignition timer or breaker which
causes quick impulses of high tension
| current to pass through lnsulateo
wires to the spark plugs. When the
spark lever is retarded the timer Is In
position where the contact points
separate and send current to the
plugs just at or little past peglh-
ming Of power stroke of each piston.
When spark lever is advanced the
timer moves to a corresponding po-
sition, creating impulses before eacn
piston reaches beginning of power
stroke, when the engine develops more
power and speed.
| g. Under normal driving condltiohe,
such as roads which are fairly leVeI
| the accelerator Is considered better
for controlling the throttle than the
| hand lever at the steering Wheel.
When the accelerator is used, leaving
| the hand lever in a set position. tne
hands of the driver are free to operate
gear shift, emergency brake lever ana
| the steering wheel; a quicker get
away can be attained and the engine
can be slowed sooner. The mana
throttle lever should only be used on
good-sized hills and for starting and
testing the engine when the car is at
! the curb.
| g. Were you ever unable to start
your engine because the starter failed
| to respond. and, upon searching Ior
| the hand crank discovered that you
/ left the crank in the garage. Ii you
never have had his experience be pre-
pared, for you probably will encount-
! er some such difficulty sooner or later
The question is to start the engine,
and the solution Is to make the car DO
| the work. There are several ways OF
turning that engine over, the easlest,
perhaps. being to coast down an, mi,
| or grade, If you are fortunate enough
| to be on a hill, placing the gears IN
high speed and holding the Gluten
disengaged until the car gains sum
cient momentum to revolVe the ehsill
when the clutch is engaged. Ine ie
milton. of course should pe T;s, sWs,' me-
| on. If you are near hill, enlist tne
services of some kind-hearted penes-
trians to push your car to the hllltop'
when YOU can proceed the same as before.
The greatest problem. and one winch ~
calls for the largest amount OF %oiH; 20
| to start the engine on level road. you
can either place your gears IN nigh
switch on the ignition, disengage the
clutch and have the car pushed along the
road to start, or by jackipg up a rear Wheei

or truck to tow your car while IN gear.
| No doubt this latter is the surest way 10
get the engine in operation. Here a
nrecamtion: il YOU are successful in
starting the engine by revolving rear
wheel do not hold the wheel after giving
| 1t a turn. The engine may peenl run, u,

letting car off the jack to the road.
| 4. II your car hasn't power enough 10
negotiate hill even in low gear. as a
last resource try backing up the mn.
You may. be surprised to find that the
car will climb the grade without much
effort, the reason being that reverse
speed is Of the lowest gear ratio OF all
transmission speeds.
| s. A carburetor primer sometimes
called the carburetor "tickler' is small
rod or lever about the same size as the
| adjustable needle valve. and is located
| in the float bowl and connected in some
way to the float. The primer rs Is usea . 10 10
| allowing the float to rise with the gaso-
line as it enters the carburetor, for the
purpose of giving a heavier charse OF
! vapor to cylinders for starting the en-
CINE when cold. When operating the
primer hold it down until gasoline starts
| to flow from the top of carburetor, when
the float chamber is filled to capacity.

I. To separate water from gasoline
strain the gasoline with wire gauze or
chamois. If there is anv water mixed
with the gasoline it cilI remain in
the strainer.
s. Knocking in an engine is most
commonly caused by loose bearings.
carbon in cylinders causing preigni-
tion and knocking at high spark,
oDening the throttle too quickly or
driving with spark too far advanced.
9. Many drivers unfamiliar with
car make the mistake of not opening
the throttle lever tar enough and of
advancing the spark lever too far.
Wondering why the engine will not
run, and also what causes the back
kicking and funny noise when the
starter button is depressed. they do
not realize that each explosion in
cylinder, being timed too soon, is
working in opposition to the starting
motor by driving the pistons back
down and revoIyiuo the eppipa be
