Motor Roy St !. Wood of Vancouver,
B. c., made this prize winning answer;
Noisy operation is generally the re
suit of some defect in the adjustment
of the various working parts OF the
motor The valve-tappets, for instance,
viii make an easily distinguishable
and rapidly recurring tick, which may
be materially reduced by adjusting
their heads until the space between tbs
latter and the valve stems is barely
sufficient to admit the edge OF a visit

Timing gears are at times RESPONSE

nature as that produced by an electric
starter. though not so loud. This may
often be eliminated by fitting new cam
shaft bearings, or even by using mucn

The crank and wrist pin bearings
of a motor. being subject to enormous
pressures, are apt to wear away 10
such an extent as to create knock

centers- This knock is of a metallic

More Suggestions

these valuable suggestions
Let US start with a premise and
work toward out O. T. D. Noise of

c0nditiOns-wear of parts or mal-ad-
justment Of parts in factory or in ser
vice In addition to these two, We
must consider early wear as due to
one. or both, of two conditiOns-im-

Of OIL supplied
Thus far the remedy is obvious The

your car or for mine. This is one way
whereby to choose oils. Or. ask advice
