If the crankshaft Is out Of alignment
so that 1t Is noticeable in engine oper-

repaired, If that Is possible, or have n
new shaft installed. You can over
come the difficulty for awhile by TAX
ing up the misallgnment In the bear

sprung, the trouble will return.

a change of oil.
When my car is standing and tho On
CINE is running with the brakes set
there is q knock in the gears. What
causes this7
You state that there IL a knock In
the gears when the motor Is running
idle. but you do not say whether you
near the timing gears or the gears In
the gear box. III Il Is the timing gears
that are making the noise the trouble
must be caused either by the gears
being loose on their shafts or else the
bearings are loose. In order to find
where the trouble Is 1t will be neces-
sary to go Owe the motor. If the knock
is In the gears In the gear box 1t must
be caused by loose bearings.
Will you please tell me whether in
making connection between two wires
II 10 preferable to splice the wires or
loop the ends and hook the loops to-
gether?
Splicing the wires has the advantage
Of making a joint that Is compact.
Such a joint takes up very little more
space than the wire itself, and a spliced
joint Is also very easy to ~insulate, as 1t
can be very readily wrapped with tape.
This joint makes a good electrical con-
nection and also Is more flexible than
the loop type. The main advantage Of
the loop joint is that 1t Is not so easily
pulled apart.

for ignition constant or do different en-.
CINE speeds or different road conditions
cause Il to varyf
The consumption Of current Is pre-.
portional to the motor speed. For in
stance, at GOO revolutions twice as
many sparks are required as at 300.
However. no more current IL required
to produce q single spark at 600 OF
1900 for that matter than il required
at 800.
