in various parts of the car where, in
their opinion, the particular type
serves best AS stated previously, the
merit of the bearing used IS determined
by its design, construction and proper
installation.

While reading your motorists. columns
in the paper I noticed an article stat
ing that the four cycle motor IS more
economical in gas consumption than
the two cycle motor. VIII you kindly
explain this to me? am greatly inter-
ested in automobile matters and would
be thankful to you for any Information
on the abOVe.-Amateur
From a theoretical standpoint the
two cycle motor is supposed to be more
efficient on account OF the less number
Of working parts and complication
Also because the power impulse is de-
liTered to the crankshaft at every rev.
oIutiou instead Of at every second revo-
luton. 1t is a known 1act, however,
that the four cycle type motor is more
efficient, both from an economical ana
mechanical standpoint
In the two stroke motor II IS neces-
sarv to compress the gases IN the
crank case and admit same TO the
cylinder through port holes, AT the
same time that this operation taxes

mechanically operated and each 1unc-
ton of the motor is timed to q degree
that permits much greater eiIIclency,
Likewise. the mixing OF the gases as
well as the compression Of the gas is
better facilitated. From a fuel stand
point the four cycle type Is much more
economical than the two cycle type

G. J.
If you can have the parts properly
welded they should give you just as
good service as new parts. When you
have this work done you should nave
the blocks and pins fitted very Closely,
allowing just enough play Tor proper
fabrication. AS soon as these parts oe-
come slightly worn they depreclaue
very rapidly. This is due to the con-
slant pounding and twisting they are

ever, they are the most neglected parts

I am the owner of a 1912 car, which
gives me very little trouble, but 1 am
bothered with excessive smoke and
very bad odor when engine is first
started. This bad odOr, however, passes
away after the engine has been run
ming for a few minutes. Can you sug-
gest a remedy for this I am using
very good grade of oil. An immediate
reply will be appreciated. w. f.
The excessive smoke is probably due
to excessive oiling. Reduce the oil
supply as much as possible. Perhaps
YOU use too light an oil In motors
which are worn considerably 1t IS IS, o ct5I.
advisable to use an oil of slightly
heavier grade. providing you do not
care to overhaul the motor and install
any new parts
The bad odor is undoubtedly due to
the carbureter. When the motor IS cold
the mixture does not burn as thorough
" as when the motor is heated After
running for some time a more perfect
combustion Of the gas takes place
within the cylinder. It is possible that
you are using a slightly Over-rich mix
ture. Would suggest that the carbur-
eter be adjusted for a slightly Ieaner Z
mixture. If by doing this you expert /
