over a stretch of rough pavement, By a
continuous hammer jar communicated
up through the column. What adjust
ment or remedy would you suggest in
order to take out this lost m6tion and
thus eliminate the latter?
Adjustments are usually provided on
the steering gear for putting the proper

gear by moving the eccentric pushing
on the worm gear shaft. This Is done
by removing the steering arm from the
end of the worm gear. loosening the
clamping screw ON the steering body or
chuck and making the proper adjust

axle, knocking the wheels out Of align

mention.

valve timing Of a gas enslne7
There is no such thing as the most
efficient timing on a gas engine. The
ideal timing for any two motors will
not be the same. The reason for this
is that the manifolds, piston displace-
ment and various other factors have a
marked influence on the proper timing.
Will you kindly tell me what 10 a
good, practical preservstive dressing
for automobile tops-something that
will not in the end do more harm than
good2
The material which you use In your
most desirable I'm keeping 1t In good
condition. If it Is mohair, CASTLE soap
and lukewarm water are best. The
other tops, which are patented fabrics
or imitation feathers. etc. will have To
be taken care of according to the sub
stance Of which they are composed.
None of them, however, will be harm
ed and most OF them benefited by the
CASTLE soap and water treatment.
My car will not fire regularly on the
rear cylinder. have had the valves
ground, the carbon removed, new pis-
ton rings fitted, but still there is no
compression on the rear cylinder. What
10 the matter?
The poor compression may be due to
improperly adjusted or poorly timed
valves. This is a common cause. and
very often after grinding the operator
forgets to readjust the tappets. Cylin-
der leaks may be causing the trouble.
Perhaps the leak Is around the spark
plug or the cylinder plug openings. A
little paste stove blacking on the
threads win prevent leaking at these
places. Do not use too much Of the
paste, but Just enough to owe the
threads lightly. The piston rings ends
may be in line and thus cause the gas
to escape in the lane made by the rings.
The piston itself may be loose or the
cylinder worn a little.
Are there any boron cutouts or our
rent regulators used in the electrical
equipment Of automobiles?
The use of the element boron for
cutouts and regulators for electrical
has been tried out, and, in
fact, many experiments are being made
on 1t at the present time. but 1t has
yet proved satisfactory. The quail
ity of boron in having the resistance
increase with Its temperature due to
the passing of an electrical current
through IL would seem to make II ideal
for use in regulators. especially since
1t has a fixed point at which the cur-
rent does not further increase. 1t
