Recently had the carbon removed
from my cylinders, but even after thai
when running about fifteen miles per
hour on top gear when want to pick
up quickly with my spark retarded be
low halfway the motor knocks very
hard. What is the cause2
The fact that your motor knocks
when the spark is halfway advanced
when YOU are accelerating from a
speed of fifteen miles an hour on high
gear does not indicate that there Is
ANYTHING wrong with your motor. Try
retarding the spark further under these
conditions and see If the car does not
run all right. The idea to keep In mind
when using the spark lever Is to set 1t
at the point just below that at which
the motor will knock under the partic-
ular conditions that the motor Is OPP
Grating under at any given time.

and three quarts of oil when up to the
pet cock lever, and have a dash sight

but when have the amount of oil !
speak Of the motor smokes. How can
stop it smoking and still know that !
have enough oil to Iubricate the motor?
The manufacturer of this motor
should have set the oil level at the cor
rect height. Therefore we would not
advise doing anything to change the
height of the oil in the crank case until
you have made sure that the trouble
Is not elsewhere. Smoking may be
due to loose fitting piston rings, worn
pistons or worn cylinders or all of
these combined. Poor oil might also
be causing the motor to smoke, or 1t
may be that the cooling system is not
working properly, with the result that
a large quantity Of the oil Is consumed
because the motor runs hot. If smok-
ing does not seem to be caused by any
of these conditions it might be well to
reduce the level of oil in the crank
case, but before taking such a step
turer Of the car or with some good re-
pair man.
My motor stops when throttle is
placed in certain notch on quadrant.
When running slow around corners or
over crossings and on speeding up,
when the throttle reaches a certain
notch on the steering gear quadrant,
the motor either stops or jerks about
six or ten yards. What is tho cause
Of this?
Probably with the throttle In a GER
tain position some part of the throttle
mechanism short circuits the ignition
current. With the "a running move
the throttle lever until the motor starts
to miss or stop; then stop the ar and
look for the trouble. 1t Is also posi-
BILE that the movement of the throttle
interferes with the operation Of the
carburetOr. See that the air valve is
not affected. If the throttle and the
auxiliary air valve are connected up.
or If the throttle in any way controls
the flow Of gasoline from the Jet or
jets, this mechanism should be care
fully inspected.

grades on second the car checks up as
if the pbrakes had been applied. Then
again it will gain speed; then slow up
as before. What is the cause?
The peculiar action Of your car is
due to temporary disarrangement of
some part of the ignition or carbure.

the trouble must be caused either by a
short circuit or a loose connection. In

tive insulation at which points the
bare wires may be grounded On the
metal parts of the car, thus detecting
the current from its regular path. &C

any that are loose. After doing this
the motor should run all right If the
trouble is with the ignition. If the

motor to run irregularly you must be

that 1t Is due to a sticking Of the aux

the mixture Is too lean, trouble may
be the result of any of the following
causes: The auxiliary air valve may
