View the Installation & Troubleshooting DVD supplied in the box. This video shows you how to install the carb on a variety of
•
intake manifolds, how to check linkage and vacuum line hook-ups, set the idle speed and mixture, and help you diagnose any
potential trouble spots.
Please note that the Installation & Troubleshooting DVD is not supplied with "As-New" (remanufactured)
•
carburetors. The entire content of the DVD is available on the Video section of the Edelbrock website (http://
www.edelbrock.com/automotive_new/misc/tech_center/install/tech_vids.shtml). Please also visit the Edelbrock
website to view the complete Owner's Manual, carburetor calibration reference carts and other technical
information not found in these instructions.

If your engine has a rough idle or hesitates off-idle, adjust your mixture screws and check your vacuum line connections. Be
sure that 1/4" vacuum opening at rear of carburetor is connected to either power brake booster or vacuum modulator
(automatic transmission), or plugged with 1/4" pipe plug supplied with this carburetor. Adjust the idle mixture screws
by turning in (clockwise) until engine runs rough. Back off screws until engine begins to idle smoothly, then back off another
1/4 turn or until engine is idling smoothly at maximum idle rpm. Vacuum lines must be connected to the correct port. If the
distributor has timed vacuum advance, the distributor vacuum hose should be connected to the passenger side (timed) vacuum
port on the carburetor. If it has full vacuum advance, it should be connected to the driver's side (full) vacuum port.

If flooding occurs it may be caused by: 1) dirt or debris stuck between the needle and seat; 2) the floats are out of adjustment
or 3) too much fuel pressure. First, take off the top of the carburetor and remove any dirt that may be in the needle and seat.
Use a fuel filter to prevent this problem in the future. Turn the top over to set the float level at 7/16". See page 8 for more
information on the float level. Make sure fuel pressure does not exceed 6.5 psi. Flooding is not a symptom of a faulty carburetor.
•
If fuel drips from the throttle shaft, this is caused by excessive pumping of accelerator pedal with engine off or heat soak.
