11. For electric choke hookup, attach the bayonet end of the long electrical lead supplied to the positive terminal on the
choke cap. The other end must be connected to an ignition activated 12-volt source. The distributor side of the
ignition coil is NOT a 12-volt source. It is a 7-9-volt source after cranking.
WARNING: Connecting the choke cap to the ignition or ignition coil could result in unacceptable choke operation,
poor fuel economy, and possible engine misfiring, since the voltage delivered to the spark plugs will be
severely reduced by the drain imposed by the choke cap. Suitable ignition activated 12-volt sources are
most electrical relays, as well as the leads to accessories, such as windshield wipers. DO NOT connect
this wire to the original equipment (O.E.) electric choke source. This may not be a 12V source.
12. A 12”choke ground wire is provided (in the kit) and needs to be attached to a ground source on the intake manifold. The
.25” male spade terminal will attach to the negative terminal of the choke cap (see Figure 7). Use the 3/8” ring terminal to
attach the wire to the manifold. NOTE: Holley® recommends grounding to the intake manifold. An anodized surface is not
a good conductor of electricity and a proper ground may not be achieved.

13. Check the voltage source with a volt-ohm meter to ensure proper voltage and choke operation.
14. Start the engine and check the fuel lines and inlet fitting for possible leaks.
NOTE: The recommended fuel pressure is 5-7 psi.
15. Recheck to ensure that all existing vacuum hoses are attached properly. Plug any fittings not used.
16. With the engine at operating temperature, set the idle speed to the manufacturer’s specifications (see page 9 for idle
adjustment).
17. Shut off the engine and readjust the throttle operated transmission linkage, if necessary. On installations that have a
kickdown-actuating switch on the passenger’s side of the firewall, it might be necessary to readjust it according to the
manufacturer’s service manual.
FORD APPLICATIONS WITH AUTOMATIC TRANSMISSIONS: With the engine off, push the transmission kickdown rod
rearward until it stops and hold it in position. Push the throttle lever rearward to its wide-open throttle position and adjust the
transmission kickdown screw to come in contact with the transmission kickdown lever tang.
WARNING: With the engine off, recheck the assembled linkage for sticking and/or proper return to the idle position.
18. Place the air cleaner gasket (supplied) on the sealing flange, and install the air cleaner.
19. With some air cleaner configurations, it may be necessary to use an air cleaner spacer to provide adequate clearance
between the carburetor and the air cleaner. Holley® offers such a spacer (Holley® P/N 17-13). Depending on the overall
height, obtain the proper length 1/4 x 20 stud and install in the carburetor airhorn. Close the hood slowly to ensure
adequate clearance between the air cleaner stud and the hood.
WARNING: Inadequate clearance between the air cleaner and the throttle lever could result in throttle sticking and
uncontrolled engine speed. Check the clearance between the throttle lever and air cleaner for proper
operation. Check the clearance between the air cleaner and the hood before closing the hood completely.
MAINTENANCE WARNING: Fuel system components, including fuel lines and the carburetor, should be inspected periodically
to ensure no fuel leakage and to ensure the soundness of the hoses. Today’s clean emissions engines provide higher
temperatures in the engine compartment. These high temperatures promote faster aging of non-metallic materials.
