knock.
Causes Of Knocks
To find out If the trouble lies in the
circulating system feel first the top
and then the bottom of the radiator.
You will find that from the water
jackets to the top of the radiator the
water will be hot, while the rest OF
the system will be cold. II your car is
cooled by the thermo-siphcn system
be sure that there is water above the
top connection of the radiator; other.
wise IT will not circulate, but will
rapidly boil away.
Knocks are caused by loose parts,
but since there is always q certain
amount OF play in the various com.

cause of the knock may be too far
advanced spark. too rich or too lean
mixture, carbon deposit, lack of oil or
lack OF water.
AS soon as your motor develops a
knock investigate IL. There Is always
the danger Of its developing into some
thing serious. A loose bearing knock
will be particularly noticeable fwhen
the motor is slowing down.
Clutch troubles are most frequently
due to slipping. The clutch becomes
worn and begins to slip. and the more
it slips the more it wears. II the sur

be due to weak clutch spring.

You should remember, however. that
batteries require careful attention;
that the lamp bulbs should be Of the
proper candle power and voltage;
that fuses OF correct rating should be
used, and that wiring. especially the
terminals, should be frequently in
spected to see that everything is in
good condition. When your lights are
too bright the reason may be a loose
connection in the circuit bulbs Of
lower voltage than that required or
improper voltage regulation. The OBJ.

Lights which are too dim may be
caused by slipping generator drive,

OF too high voltage and also by run.
