| (a) A strong solution Of aIkaIi and
water is good to remove foreign mat
ter from water jackets. The sOlu-
ton should not be allowed to remain
In the motor longer than 20 minutes
! CD There are several causes for over
heating when climbing hills. The cool
/ ing system may pc defective, the cyln-
| qers may be carbon1zed5 there may be
{ insufficient fabrication, or possibly the
[ spark Is not advanced sufficiently.
{ Many cars VIII overhead when elm bling
/ hills and not overhead under other con-
( diuons- When a car is climbing a hill
[ on the lower gears the motor is turning
| over very fast while the rate Of speed
| Of the car is slow The rate Of speed
| OF the car has great deal to do with
/ the cooling OF the motor For example,
l when the car is travelling in high gear
| approximately Is miles an hour the mo-
/ tor is turning over reasonably slow
| and the cooling area due TO the air
I pressure on the radiator is largely in
creased In climbing hills in low gear
I the motor turns over very fast at full
/ InrOJtle, ana the cooling area IS consld-
I erably reduced, due to the speed OF the
I car being slow. 1t is true that the ian
/ revolves at speed prOpOruonate to the
1 engine speed nevertheless the additl n
I al cooling effect attained by a slight
! wind pressure determines more or less
| the temperature Of the motor. This
seems rather small factor to cause the
| overheating, but when you consider
! that the cooling system is designed to
keep the motor at a temperature just
/ below the boiling point under normal
{ conditions, you viii appreciate that
[ very little VIII produce Overheatfne
I when the motor Is worked hard Often
4 a rich carburetOr mixture viii produce
OVerheaLing under normal conditions.
| Co Usually the space between the tap
pet roo and valve stem Is ABOUT l-b4Ih
OF an inch,s or enough to allow for e1-
pans1on and contraction. This ADJUST
| ment IS made when the cam OF the cam
I shaft is in no way acting upon the push
rod Each valve stem should be ad-
= 5usted in a like manner.
/ I'D 1t Is impossible to state the slow
est speed YOU should obtain when the
! motor is full throttIed- This depends
entirely upon the gear ratio.

Ny car has not the power that a motor
| Of its size should have, although the
| car has just been Overhauled- She runs
I beautifully up TO a certain speed from
/ there on she slows down instead Of
picking up, no matter what carburetOr
adjustments The only thing that I
can find out is the acting Of my aux
11ary air valve in the carburetOr. She
mas steady pull up to a certain speed,
then she starts to Flap up and down
A Kuhn.
Your trouble seems to lie in the car
I buretOr adjustment The spray nozzle
may be too small to furnish sufficient
gas at high speeds Also the air valve
It is possible that by using a stronger
| air valve spring your trouble may be
remedied Would suggest that you in
| air valve and readjust carburetor to
meet the new conditions.

I have been running a heavy motor car
for some time. / have had two acci-
! dents with my machine while shifting
the lever from first speed into second
| speed Now, while the lever would
| shift over into second speed. the first
would chop back from neutral What
much gas2-M SchofieId
| The ball lock which holds the first
| speed gear in the neutral position IS
evidently faulty, and does not perform
its proper function. Two speeds meshed
| at the same time viii prevent the trans
/ mission shafts from turning. in which
case the teeth Of the gear must break.

l wish to light my car with four
candle power buIbs-twO side lights and

cells would you advise ?-Owner
/ 1t is possible TO use dry cells for the
! purpose YOU speak Of, but they would
] prove neither economical nor satisfac-
| tory. Assuming that you use six-vOlt
/ four candlepoWer lamps, you VIII find
] that the three lamps viii use almost
/ an ampere OF current, which would
/ mean that a set of dry cells in first
lighted very long 1t would also be nee
I esSary to use at least six dry cells
/ connected in series to light them at
all. and after once having exhausted

have to be replaced While the initial
cost Of storage battery is rather high,

hours or more and can be reCharged
