Introduction
The Ford Model 2100 is a single stage two barrel carburetor used in Ford applications starting in 1957. This manual covers the 1958-1975 Ford
applications, including the 2100D model (cover illustration). The 1957 model has a unique accelerator pump system and is not covered.
The Model 2100 was variously referred to as a Ford, Autolite or Motorcraft
carburetor. It consists of two main body sections, both cast of aluminum: the
throttle body and the air horn (float bowl cover). The choke housing and venturi
cluster insert are made of zinc. Most model 2100 automatic choke carburetors
used an internal choke pull down piston inside the choke housing as a vacuum
break to open the choke on start-up. Model 2100D carburetors use an external
choke pull down diaphragm mounted on the air horn behind the choke plate.
Some 2100D carburetors also used an external choke pull off mounted on the
passenger side of the carburetor.
In general, the complete carburetor number was only found on a metal tag attached to the air horn. In many cases, part of the carburetor number is also stamped on the driver’s side of the carburetor near the front mounting stud. This can sometimes be used to identify the unit.
Ford Carburetor Number Decoding
All Ford carburetors have the basic part number ‘9510’; this not normally included in parts listings for carburetors.
For example,
C4DF-9510-AB
is a carburetor used on a 1964 Ford Falcon with 260 CID motor, and is usually referred to as C4DF-AB.
“C” means 1960’s
“4” means 1964
“D” means Falcon (called the Model Basic Design digit)
“F” means the design came from the General Parts division of Ford (called the Engineering Component digit)
“AB” identifies the particular carburetor design.
Decade Code
B = 1950’s
C = 1960’s
D = 1970’s
Model Basic Design Digit (3rd character in the number)
A = full size Ford
D = Falcon
E = truck (also T)
F = foreign
G = Comet or Montego
H = heavy truck
J = industrial or marine
L = Lincoln
M = Mercury
O = Fairlane or Torino
S = Thunderbird
T = truck (also E)
U = van
V = Lincoln
W = Cougar
Y = Meteor (Canada)
Z = Mustang
Engineering Component Digit (4th character in the number)
E = engine group
F = general parts
Note that only options relevant to the carburetors covered by this manual are
listed. Also, the carburetor number generally indicates the model or division for
which it was originally produced. Thus a carburetor with the third digit for
Mercury might also be used on a Ford. In some cases, a carburetor number is
used in more than one year. The date is then the year for which it was first
designed.
An additional number is cast into the driver’s side of the throttle body. This is the venturi diameter in inches. A common size for smaller engines is 1.08 (inches); this would indicate the carb came from a 289 or 302. A 1.12 or larger carburetor would usually be from a larger engine, such as a 390.
Restoration Tips
Finishes
The throttle body and airhorn are finished in natural aluminum. Cleaning in acid
can darken the finish and should be kept to a minimum. Blasting with very fine
(#8) glass beads followed by a chromate dip will restore the finish.
The choke housing, venturi cluster and (in most cases) the power valve cover are olive-green chromated zinc.
Airhorn screws are 10-32 Fillister head slot screws through the late 1960’s; some
later models used Phillips head. The finish on the screws is clear or yellow zinc.
Problems
The 2100 uses a steel throttle shaft which may wear into the aluminum throttle
body.
If necessary, bronze bushings can be installed to restore the proper clearance. This requires special tools and is generally a job for a professional. The bushing size is 3/8” ID, 7/16” OD and ½” long.
Occasionally, the underside of the throttle body is distorted. The body should be
checked along both diagonals with a straight edge and machined flat to prevent
air leaks, being careful to remove the minimum possible amount of material.
The power valve cover, when made of zinc, is almost always distorted. This
results in an air leak causing premature operation of the power system and a rich
mixture. It should also be planed flat; a belt sander or large file may suffice.
