on 355-D and a .004 in feeler gauge on 370-D and
452-D engines will just go between the throttle
butterfly valve and the carburetor body with the
valve in the closed position. The kicker adjustment
is made by setting the choke lever in the open
position and turning the kicker screw until a .017

on 370-D and 452-D engines will just go between
the throttle butterfly valve and the carburetor
body with the throttle in the closed position.
All other service work on the new carburetors,
such as their removal and disassembly and the replacement
of parts is the same as on the "C" series
12 and 16 cylinder engines.
Automatic Choke
All cars are equipped with a semiautomatic
choke (Fig. 41), which permits a more efficient
choking of the carburetor during the warming up
period than is possible by the manual choke control.
When the engine is cold before starting, the
semiautomatic choke is automatically in the choke
position, i
The
manual choke on the instrument panel
should be used as necessary when starting a cold
engine but should be pushed in immediately after
the engine starts. The purpose of the semiautomatic
choke is to keep the engine from stalling
Fig. 40. Cool fresh air for the carburetor is secured
through a passage in Ihe radiator casing
Fig. 41. The purpose of the semiautomatic choke is
to keep the engine from stalling and to prevent
popping back into the carburetor during the warming
up period
and to prevent popping back into the carburetor
before the engine has reached the proper operating
temperature. As the engine warms up, the thermostat
starts to open the choke so that when the
engine has reached its correct operating temperature,
the semiautomatic choke is in the full
open position.
Gasoline Tank Filler
The gas tank filler on the Series 10 and 20 cars is
located in the lefc hand side at the rear of the body.
The Fleetwood cars have the filler located on the
top of the left rear fender. This filler has a double
curve where it goes down from the center of the
fender through the side of the wheel housing, then
through the rear floor down into the tank. The
filler is protected from stones and gravel thrown
up by the wheel by a specially constructed stone
guard which is fastened to the fender and the side
of the wheel housing.
On the Fleetwood cars, the inside of the filler
neck is protected by a cover which is bolted to the
rear floor and inside of the wheel housing. A
rubber ring is also used in the wheel housing to
keep out dirt.
