What TO Do in Case of Trouble


metal. A good proportion Of them are
made OF cork so treated that they VII!
not readily become gaso!ene-iogged;
Even at that, cork cannot be considered
exactly the best material for the pur-
pose, because its buoyancy varies. A
cork hoat from constant use becomes
logged 70 q greater or less extent, ana
It's buoyancy decreases accordingly. On
the other hand, II IL has not been IN use
FOR some time and Is left dry the pro-
tec,ing varnish may crack and chip on
not only causing the float TO become
readily logged, but also causing Mood

T. is wise 70 look over the earburetor
Aoat once in a while 70 see whether It
needs attention.
Watch the operating mechanism, too,
for il is necessary that the toggle lev
ers. and in fact all mechanism which
makes I'd your carburetor, should work
freely. so that none Of the moving
parts bind or jam. There is also a
possibility that flooding will result II
the carburetor happens to be one OF
delicate design and requires that II DC
kept level.
Having covered the flooding subject,
now let us give liberation 20 the
opposite difficulty, the starved carbu-
rotor. Constant back-firing may be the
trouble, for example: Eight out or ten
times a lean miXture will be found 20
be the cause. although this is not al
ways the case. The first thing to do
is to see If the gasolene IS turned on
full, if at all. This may seem fool
ish precaution, but not infrequently a
careful driver turns off his gasolene
when he puts up his car for the night
and fails to remember to open X
when he starts off on tour. OF course,
it may happen that vibration VIII
change the position Of the tap while
driving and the gasolene be turned on
Another cause of insufficient gasolene,
reaching the carburetor Is chokeo
fuel pipe, and if stralner or inter
ing arrangement Is not fitted 70 the
car steps should be taken TO add one
as soon as possible, as much trouble
may be saved by so doing.
II also will happen that the air vent
IN the ton of the gasolene tank OF
in the cap becomes clogged. This mas
often caused car to stall at most
inopportune moment, and should there

with water. and starving may be traced
70 a chokage of the filter. There Is
also a possibility of small passages
in the carburetor being filled with sedi'
ment. and in order to take time by the
forelock il is advisable that these b6
cleaned out from time to time 70 pre-

Beware the Choked Jet.
/ The most frequent trouble in regard

particle Of dust or dirt having become
lodged in the tiny passage. If this mas
occurred the jet should be removed foi

Manipulation with these tools is Liable
to cause two things. The needle may
break off in the jet and leave you il
a worse state than before, while the
awl will enlarge the opening OF the jet
and the entire balance of the car
buretor will be upset
Many foolish mistakes can be made
in attempting to diagnose carburetol
troubles. These should not occur, since
there are really only two requirement
necessary for one to ascertain the dit
ticulty. They are a good knowledge
of the particular carburetor used an'
common, ordinary horse sense. If
csrburetor floods it cannot possibly b.
due to a chokcd gasolene pipe; simi
