Il have Buick, model C-37 and
would like to ask few questions
concerning same:
/. When / press the accelerator
there is kissing or sucking sound
and the enigne will not respond This
only happens at times. The vacuum
system seems to work o. X. as there
is plenty of gas getting to the car
burctor.
2. The engine will run fine for
while, when it will begin to fire in
the muffler and seems to buck with
every explosion. This only happens
occasionally or when pulling hard.
Can you tell me where my troubles
are? I thank you in advance for
same. AN AMATEUR.
l. The air valve may be out of ad-
iustment or the stem caught by grit
Work out the grit by pouring gaso-
line down along the stem and moving
the valve. If this does not remove
the trouble. adjust the valve spring
to make it stronger.
2.rhe bucking and explosions are
due to one or more cylinders miss.
ing explosions. This may be due to
air-valve troubles, as above, or com
preston or ingition troubles. Only a
thorough search can reveal the cause

Would it he possible or advisable
to fasten some device to the brake
rods, so that the following driver
would know when to keep clear Of
MY car? 1t would, of course, be il
Eliminated at night, and as that Is
The most dangerous time red light
would be the best. Please tell me
what you think of the idea.
T. X. B.
Many such devices, including indi
,ators to show which way the car is
yoing to turn have been tried ou,
nd proved satisfactory However
none Of them seem to have taken the
ancy of owners or drivers, so ap-
oarently the time is not yet ripe for
such device.

Occasionally Il small spurt of gas
3line runs out of the air tube on my
facuum tank, particularly when start
ng up, Sometimes ] notice pop
ing sound at the carburetor. These
roubles are of recent development. 7
would thank you for any suggestions
Tor locating and remedying thes,
troubles. j. NJ. T.
Evidently one of your inlet valves
leaks causing a popping-back at the
arburetor and a pressure in the vacu-
I'M tank which causes the gasolin,
run out at the top. Warm up en-
gine, then stop it and test compress
iion. Note carefully if inlet valve Of
weak cylinder is touching valve lift
II, holding it open. 1t should just
clear it, If valve does not touch lift
II even when hot, remove it and Sc
{ it is bent or needs grinding.

IN My 1916 model .Ford motor.
when throttled down TO eight miles
IN hour or less, jumps as if one OF
.wo cylinders were missing, and if
5aekfires badly. have tried regulat
ing mixture to overcome trouble with
out much success except to accelerate
motor beyond the speed where the
trouble occurs and to cause trouble in
other directions. My cylinders and
plugs are clean and free from car
bon; magnet coils and wiring are in
apparent good order and adjustment.
(2) What causes one cylinder (No, 4)
to collect greater amount of carbor
than the remeaining three? e. H. B,
(1) The fact that the engine jumps
and gives muffler explosions shows
that the cylinders are not firing prop
erly; break IN Umer wire or
cracked core in a plug might cause
this. Locate missing cylinder and Try
changing the coils around, then the
timer wires, and last the spark plugs
If the trouble follows the change It
should be easy to locate. (2) Tho pis-
ton rings may be worn or broken OF
the connecting rod dip more freely
into the oil than it should This could
only be determined by a thorough
overhauling Of the engine.

is there any advantage in having
the clutch connected to the emerg-
ency brake and foot brake so that
setting the brake disconnects the
clutch and makes it easier 10 stop the
