My carburetor has troubled mo by
flooding when the engine of my car is
not running. What is the cause of this?
| have been told to turn the float
valve in it's seat and so scat IL perfect
ly, but this does not help any. Have a
great deal of trouble making the motor
hit evenly when first starting up. The
engine never has pulled. very well or
hills. Can you tell mo Wfiat Is wrong?
The leakage in your ,carburetor is
possibly due to the dirt In the gasoline
having lodged under the needle valve
and holding it partly opened, or else
the valve itself is not seating properly.
Our advice in this instance would be
to disassemble the carburetor for the
purpose Of a thorough cleaning and
also reseat the needle valve. To do
this properly place. a small quantity OF
white lead on the tapcred portion of
the valve; then replace the valve and
spin few turns by the use of a screw
driver. Remove the valve. clean off
the white lead and when replacing
hold valve firmly down in its seat and
tap the stem lightly with a hammer.
1t also would be well to adjust the
float so that it stands at about one
eighth of an inch below its. proper
level.
The trouble experienced in getting
the motor to hit evenly when first
starting up no doubt is due to 9improp-
er handling of the carburetor dash ad-
Justment. When starting the motor,
especially IL it has been standing for
any time. it is advisable to move the
lever regulating the dash well down on
the starting side of the dial, which
practically shuts off the air passage
and allows certain amount of raw
gas to be drawn into the cylinder, and
after the motor becomes warm the le-
yer gradually can be moved back to-
ward the running side of the dial to
a position on which it is found the mo.
tor runs best under ordinary condi-
tons. f
The lack of power mentioned may be
due to the valves not seating properly
or being incorrectly adjusted, and it
would be advisable for you to have
these gone over-ground in, IL neces-
sary-and when adjusting leave a
0.006 inch clearance between the end
of the valve stem and the face of tap
pet adjusting screw when the valve is
properly seated. This adjustment
should be made when the motor is cold.
1t also would be well to note whether
the clutch is holding properly, as, If
this slips on hard pull, naturally the
full benefit of the motor power is not
being obtained. 81. $50.
Cylinder No. 2 on my four cylinder
car leaks compression between the
piston and the cylinder into the crank
case, while the other three cylinders
are as good az new. Would fitting the
defective cylinder with new piston
rings cause the compression to be more
than the others and perhaps start vi
bration? 3E
1t is impossible to say whether the
No, 2 cylinder would be benefited
greatly by the use of new piston rings,
because the leak might be due to bad
scoring from the cylinder. in which
case it would have TO be rebored. II
it is due simply to uniform wear the
fitting Of new piston rings. and more
particularly the nonleaking type Of pis-
ton rings. probably will prove rem
edy. However. this leak may be caused
by the slots In the piston rings coming
In line. In which case new rings will
not be necessary and you swili need
only to space the slots In the various
rings so they do not come in line.
