55101_Instructions
Remove air filter from carburetor and determine the
type of automatic choke on the car. There are two
basic types:
Integrated
choke
If automatic choke thermostat is an integral part
of carburetor body and uses a black cap or plastic
or metal disc, it is an integrated choke. Follow the
first set of instructions for integrated choke.
Non-integrated
choke
If a rod connects the carburetor choke shaft to
the thermostat mechanism which is located in
the intake manifold, it is a non-integrated choke.
Follow the second set of instructions
for non-integrated choke.
INTEGRATED CHOKE
INSTALLATION
INSTRUCTIONS
STEP 1:
Remove the black plastic cap or metal disc. If a
heat tube is attached to the choke cap, remove
and discard it. Do not remove if it is attached to
the carburetor body. Save all screws, retainers,
clamps, etc., for use in installing this kit. Make
sure the choke shaft and choke butterfly operate
smoothly. If not, clean with choke cleaner.

Disclaimer: It is impossible in these instructions to account for all possible circumstances or situations that you may experience when
attempting to install this product. Please consult with a qualified auto technician before attempting to perform any work you are not qualified to
do. Automobiles can be hazardous to work on; be sure to take all necessary safety precautions. Failure to do so may result in property damage
or personal injury. Certain motor vehicle standards and performance requirements may apply to your motor vehicle (such as Federal Motor
Vehicle Safety Standards by the National Highway Traffic Safety Administration). Be sure that your work is performed in accordance with such
standards and that you do not disable any motor vehicle safety feature.
STEP 2:
Determine which of the two plastic caps included
in this kit best fits your carburetor. Discard the
one you will not need. On some carburetors, the
flanges of the cap fit between the three set pins.
On others, the flanges will fit securely within the
carburetor body.
STEP 3:
Breakaway line
Activator lever
Activator shaft
R-clips
Activator shaft
Choke butterfly
Crimp tight
with pliers (do
not remove)
Choke
tang
Insert the actuator shaft in the new plastic cap,
with the activator lever inside the cap. If you are
using the larger cap, insert the activator shaft
assembly (first illustration) in the cap as shown
in the second illustration and set depth. If you
are using the smaller cap, the activator lever will
have to be shortened at the break-away points
as shown in the first illustration. This is done by
grasping activator lever with pliers above break-
away line and then bending back and forth until
the excess portion breaks away. Do one side at a
time. Set the depth of the activator lever within
the cap so it will catch the choke tang in the
carburetor (third illustration), but not so deep
that the activator will bind on the choke housing.
Once the exact position has been determined,
remove the shaft and install the inside R-clip.
Then place the shaft in position again and install
outer R-clip (second illustration).
