bon. Have tried several kinds of oils
claimed to be of good quality, of medi-
UNI thickness, but still have carbon.
Have to remove it two or three times a
season. Can you give me any ideas on
this subject?
We have had no experience with
peroxide Of hydrogen, but since it is a
compound that is very similar to water
we doubt that its action is very much
different, and since water is SO much
cheaper it is preferable. 1t would not
hurt the motor. We have been inform
ed by several motorists that water fed
through the carburetor while the mo-
tor is running is an excellent carbon
remover, although we cannot vouch
method is simply to speed the motor
up a slight amount above idling speed
so that there will be no danger Of
stalling and then pour the water into
the carburetor In fine stream. If the
motor starts to slow down the rate Of
pouring should be reduced.
The only difference between water
and hydrogen peroxide is that the lat
ter has twice as much oxygen in 1t as
the former, and when the peroxide Is
heated 1t gives off the excess oxygen
and becomes plain water, and just how
this might affect the removal of the
carbon is problematical. Before at
tempting to theoriZe on this point it is
well to draw attention to the probable
reason that water acts as a decarbo-
nizing agent. The water in the mix
ture that comes Ia contact with the
carbon moiStens it, and when the ex-
p10sion occurs this water is suddenly
converted into steam, thus loosening
some Of the carbon. The peroxide I'M
doubtedly intensif1es this action. In
other words, it should be possible to
feed less peroxide than water to &C.
complish the same result. It is hardly
probable that the peroxide has any
chemical action on the carbon, although
1t is barely possible that when the
oxygen is released from the peroxide
it attacks the carbon and forms car
bon monoxide or dioxide.
Possibly your trouble with carbon is
due to too rich mixture and not to
the oil you use. If your motor is be-
coming old it might be well to use a
heavy oil.
have 1910 car which has magnetic
only for the ignition system. find il
difficult to start tho motor this year, al
though last year had no trouble. Can
you tell me what is the matter?
When starting On magnetic the spark
lever should be advanced. If this is
done and your engine does not start
easily, then clean and readjust the
platinum points on the circuit breaker.
Since you have 1910 car and have
used it considerably we should advise
your having the magnets remagnet-
lied.
How can the wear in the worm on q
steering gear be taken up7 Through
the new processes of welding can the
cogs be filled up and dressed down to
proper size?
Usually the wear can be taken up by
adjusting. Examine your gear for
nuts that might be used for this pur-
pose and turn them first one way and
then the other to see what effect is had
on the lost motion. Before this is
done the front axle should be lacked
up so that any change in the adjust
ment can be more easily noted.
Your suggestion to weld extra metal
on the gear Is not good one, although
it could be done. The objection is that
the method is too costly In this case,
although there are times when 1t may
be used. You must remember that aft
er the metal is welded on the surface
is rather rough and must be machined.
This would be just as expensive and
not nearly as satisfactory IS making
new worm.
If you cannot find the adjustments
you should take it to a repair man, but
be sure that he is a man with a repu-
tation for good work.
What effect does wheel base have on
the amount of toe-in for front wheels?
What effect does the diameter of the
wheels have? What, If anything else,
affects tee-in2
Neither wheel base nor wheel diam
eter affects the amount Of toe-in. The
wheels are toed In because there Is
then no danger OF their becoming toed
out. Il the wheels were perfectly
straight to begin with wear in the
steering mechanism would cause the
wheels to toe cut, thus producing a
strain on both tires and steering mech
anism. To prevent this condition the
wheels are toed in, so that wear in
the joints or elasticity of the parts
will not be sufficient to allow the
wheels to toe out.
