THE practical method usually
used IN removing storage battery
terminals IS to drill a hole through
the terminal into the center Of the
post, then pry off the terminal with
fiat file or scrswdriver. Use a =
drill for one inch posts, and IS drill
for q Inch posts.
5-The practical carburetors in use
by the average cars OF today are
quite similar in construction and
operation They are composed OF the
following parts. Gasoline inlet, con-
troled by choke valve, float cham

ventura tube or mixing chamber,
spray nozzle, auxiliary air inlet, con-
troied by a seating disc valve. a main
air inlet. controlled BY a disc operated
usually from the dash and a gas out

buretor through the fuel inlet, flows
to the float chamber The float rises
when Il automatically closes the inlet
valve connected to IL, shutting off the
flow on suction stroke OF each
piston In the engine. the gasoline IS
drawn in yapOrized form into the
mixing chamber through the spray
nozzle. which vaporizes it and mixes
with it air drawn throug the main
and auxiliary air inlets. The charge
is sucked into the cylinder from the
mixing chamber, past the throttle
disc and gas outlet The amount OF
each charge Is regulated according

the amount Of air regulated by ten
sion OF the spring which holds the
auxiliary valve firm, and amount Of
suction IS controlled by speed OF the
engine together with the space left
open by the throttle disc Most car
buretors have a drain at the bottom
OF the float bowl. used for flushing
out sediment which may collect in
the carburetor. Some carburetors
have warm air passages surrounding
them. connected with the exhaust
manifold or pipe The purpose Is 10

The system Of insurance for au-
tomobiles is based on cooperation OF
the Insurance companies. their total
experiences, rather than those OF the

The reduction OF collision or accident
premiums can be accomplished by
the addition and constant carrying Of
approved bumpers, as a protection

10-Automobile driving shafts are
OF two kinds usually, the enclosed
shafts and those not enclosed Open
shafts mostly use two universals, and
enclosed shafts but one If no uni
versals were used, strain to the
shafts would result. because the rear
