7 noticed a mechanic in wiring up my
car arranged for the cylinders TO get
their spark in 1884 order. Is JhaI
the way all four cylinder engines
no. A four cylinder motor must
either fire 1913 or 1-3-4-2, because
the crankshafts Of all four cylinder
motors are made so that the plsrOns
No. / and No. 4 travel in unison, and
No 2 and No. also On unison at $50
degrees from No. 1 and No. 4. II mas
been found by experiment that there
is less vibration in this arrangement
than there would be if No. / and No.
piston worked together directly oppo-
site No. 2 and No. 4. The camsnafr
construction decides the above order
Of firing. The ignition wires must be
placed in accordance

Ny two cylinder car has been run
about 5000 miles. Lately I had il
overhauled, and since then have had
trouble with Overheating- The eX-
haust pipe gets red hot and the water
boils after running a few miles What
do you suppose is the trouble? R. K
Either the valves are timed late or
the spark is timed wrong. If the
valves are timed properly and the
spark is set right the motor should
not overhead, as you state. The con-
dition of the exhaust manifold sug-
gests either valve or ignition timing

Advise me what the compression IN
pounds per square inch on the aver
age car.
Does the compression increase as
the speed Of the engine Increases
Has the use of fiber for timing gears
proved satisfactory? c. j. B.
The average compression is about
IS pounds to the square inch.
The compression increases Slightly
with the speed, due mostly to greater
heat efficiency.
If properly constructed, fibre and
bronze gears viii work well. The
tendency of late design, however, is to
eliminate fiber altogether.

After the engine of my car has been
running for a little while the carbu-
rector runs dry, but it only does this
when 7 start up the engine the first
time in the day. Otherwise it never
gives me any trouble on the road
either driving or running idle The
auxiliary tank on the dash remains
full, and the hole in the cap is quite
clear I have opened up the valve
that shuts off the gas from the car
buretor a little more, but it does not
remedy the trouble. have taken the
but find nothing to stop the gas from
flowing. Can you assist me in Iocat-
ing the trOuble2-OWner
Would suggest that you inspect
carefully the float valve and pivots Of
float. Also note whether float sticks.
1t is possible that overnight. cOrrOsion
Of the parts causes them to stick for
a time when first starting. Since
your trouble disappears after motor
has been running a few minutes, this
seems the most probable cause Of your
trouble.
