making II impossible to adjust cor
rectly. Try turning down the ad-
justing valve. while the engine is
running, until the carburetor back
fires or the motor slows down ap-

engine runs best. If this does not
increase the mileage have the car
buretor inspected at a service sta
ton. See that your ignition is timed
correctly and make sure that you
run with spark advanced at all times

Motor Department - My differen-
tial on rear axle has developed a
peculiar humming or singing noise
that is very annoying. 1t does not
seem 10 be so noticeable very early
in the morning and disappears on
rainy days. Can you suggest a
remedy7 J. o.
The trouble probably is In the ad-
jutment OF drive pinfon with ring
gear on differentiai. This f. due to
wear, which may be removed by
careful adjustment. Do not move
IL over so far that II Will bind, as
the increased friction will make the
car lose power. For the present a
heavier grease will help slightly.
This is shown by the fact that there
is less noise when the grease is cold.
Motor Department. have a 1918
Buick car which has been run less
than 500 miles since It was over
hauled two months ago. The en-
CINE runs finely when going over 10
miles an hour. but IL knocks and
pulls the :ar in jerks when going
about 10 miles an hour in high.
Could you tell me what the trouble is
and how TO remedy It? Thanking
you in advance. A L
Such a trouble is difficult to locate,
as 1t may be due TO improper mix
ture or 20 some ignition trouble.
Improper mixture may be due to
some part Of the carburetor being
out of adjustment or a leak in the
inlet manifold. Ignition trouble may
be due to a loose wire, poor contacts
or a short circuit in the distributor
that becomes troublesome at certain
speeds. These will require inspection
and adjustment by an experienced
man First be sure that the trouble
Is not caused by defective plugs or
dirty distributor points. These
should be cleaned and properly ad-
justed-
