causes this7 49,
You state that there is knock in
the gears when the motor is running
idle, but you do not say whether you
mean the timing gears or the gears IN
the gear boz. II 1t 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

Will you please tell me whether in
making connection between two wires
il is preferable to splice the wires or
loop the ends and hook the loops to.
sethsr7
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 insuIate, as Il
can be very readily wrapped with tape.
This joint makes a good electrical con
nectiOn and also ia more shexible than
the loop type. The main advantage Of
the loop joint Is that 1t Is not so easily
pulled apart.

The consumption Of current Is pro

stance, at coo revolutions twice as
many sparks are required as at 300.
However, no more current is required
to produce a single spark at 600 or
3,OOO for that matter than is required
at 300.
