HOLLEY REPLACEMENT CARBURETOR           

GENERAL INSTALLATION INSTRUCTIONS

To preserve warranty, these instructions must be read and followed thoroughly and completely both before

and during installation. Holley Replacement Parts Division cannot and will not be responsible for any

alleged engine or other damage, or other conditions resulting from misapplication of the carburetor

described herein. 

WARNING! This carburetor is NOT desiqned for use with ANY automatic overdrive transmissions. If

used on an automatic overdrive vehicle, SEVERE transmission damage WILL result.

Prior to and after installing your replacement carburetor, manually operate the throttle lever and choke

mechanism. Check for any throttle binding or other malfunction. Also, make a visual inspection of the

carburetor, looking for bent levers, missing parts or any possible shipping damage. Because this replacement

carburetor is designed to fit a variety of applications, It may provide more vacuum fitting tubes and/or hoses

than the original carburetor. Some provided small parts might not be needed in various applications.

REMOVAL: 

Before disconnecting the various hoses, linkages, and springs from original carburetor, it's advisable to tag each in

some manner, so as to avoid confusion during installation of your replacement carburetor. Be sure to trace each

line from original carburetor to its component, such as the distributor, then label that line. In the event that any

components are strange or unknown, use a numbering system that corresponds each line to its component.

1.  Label and disconnect all vacuum hoses and electrical lines from the original carburetor. Disconnect the fuel

line and retain the clamp.

WARNING! Carefully protect the open end of the fuel line, so that no foreign particles can enter. Wrap the

end of the fuel line with a clean lint-free cloth.

2.  Remove the carburetor hold down nuts. Loosen and remove the old carburetor.  Place it over a suitable

container and turn it upside down, in order to drain all the remaining gasoline from the fuel bowl.  WIPE UP

ANY SPILLED FUEL TO MINIMIZE A FIRE HAZARD.

3.  Clean the gasket surface thoroughly. Place a clean cloth over manifold opening to prevent any foreign

materials from entering engine.  Protect all exposed ends of lines and hoses from dirt contamination.

CAUTION: Dirt entering the engine will impair vehicle performance and can cause expensive engine

damage.

INSTALLATION:

1.  Place the new carburetor next to original carburetor.  Transfer any solenoids or dashpots from the original

carburetor to new carburetor (if applicable).

2.  Place your new carburetor and gasket on the manifold and tighten down the hold down nuts.

CAUTION: Overtightening the carburetor hold down nuts can result in a warped or cracked carburetor

throttle body. The hold down nuts should be tiqhtened down progressively in a criss-cross

pattern, first by hand, and then with the proper wrench. This procedure will prevent vacuum

leaks, while avoiding damage to the carburetor.
