INTRODUCTION

A  carburetor  is  designed  to  meet  the  particular 

requirem ents  of  the  engine,  transmission  and  vehicle  and 
although  they  may  look  alike,  they  are  not  always 
interchangeable.  Refer  to  carburetor  part  num ber  an d /o r 

specifications.

This  section,  divided  into  sub-sections  by  carburetor 

model,  covers  the  repair  procedures  for  the  various 
carburetors,  assembly  and  disassembly  procedures  and 
internal  carburetor  adjustment.  A lthough  illustrations 
showing  bench  operations  are  used,  most  single  operations,

when  not  part  of a general  overhaul,  should be  performed  (if 
practical)  with  the  carburetor  on  the  engine.  Typical 
illustrations  and  procedures  are  used  except  where  specific 
illustrations  or  procedures  are  necessary  to  clarify  the 
operation.

Refer  to  Passenger  C ar  or  Light  Duty  Truck  Service 

M anual  Section  6C  for  external  carburetor  adjustm ent 
procedures.

MODEL  1 ME  CARBURETOR

DISASSEMBLY

Place carburetor on  a holding fixture to prevent damage 

to  throttle  valve  (Fig.  6C-1  and  2).

Air  Horn 

Removal

1.  Remove  choke  vacuum  break  diaphragm   hose.

2.  Remove  vacuum  break  diaphragm   assembly  from  air 

horn  by  removing  two  attaching  screws.  These  screws  have 

a  tapered  head  and  do  not  use  lockwashers.  Remove 
diaphragm  plunger stem from diaphragm  to choke lever link. 
(Fig.  6C-3).

CAUTION: 

Screw that retains  vacuum  break lever

 

to  choke  shaft  is  installed  with  thread  torque

 

retaining compound.  It is not necessary to remove

 

this screw and lever unless choke shaft replacement

 

is required.

3.  Remove  fast  idle  cam  attaching  screw;  then  remove 

fast  idle  cam  (Fig.  6C-4).

Remove choke rod from choke coil lever on end of choke 

shaft.

4.  Remove  electric  therm ostatic  coil  assembly  from

choke  housing  by  removing  (3)  screws  and  retainers.

5.  Choke  coil  housing  need  not  be  removed  from  float 

bowl  unless  replacem ent  is  necessary.  To  remove  choke 
housing, remove three attaching screws from float bowl. Two 
screws  have  lockwashers  and  the  one  facing  the  choke 

housing  has  a  tapered  head  for  locating  choke  housing.

6.  Remove  four  remaining  air  horn  to  bowl  attaching 

screws  and  lockwashers  (three  long  and  one  short  screw).

7.  Remove air horn by lifting and twisting back towards 

choke housing so that the choke coil lever link will disengage 
from  the  choke  coil  lever  at  the  choke  housing,  invert  and 
place  on  clean  bench.  A ir  horn  to  float  bowl  gasket  can 
remain  on  bowl  for  removal  later  (Fig.  6C-5).

Disassembly

1. 

If required,  the  choke  valve  and  choke  shaft  can  be 

removed  from  air  horn  by  removing  the  screw  that  retains 
the  vacuum  break  lever  to  the  choke  shaft.  Care  should  be 
exercised  when  removing  this  screw  because  it  is  retained  in 
place by thread  torque retaining compound.  Remove the two 
attaching  screws  from  the  choke  valve,  then,  remove  the 
choke  valve  and  choke  shaft  from  air  horn.

NOTE: 

The  choke  valve  screws  are  staked  in  place  so
