How To Adjust A Edelbrock 1406 Carb. Start the engine and let it warm up for a few minutes. I ran it first with the stock jetting, and the hesitation was *much* worse.
The carter/edelbrock afb and avs carburetors are decent right out of the box, but learning to tune their fuel metering system will make them really come aliv. Step 2 locate the two adjustment screws on the front of the edelbrock carburetor, just below the nameplate. Close the left screw all the way.
Step 2 loosen the screws, but do not remove them. Once you verify there is no leak, then use the edelbrock procedure to set the idle mixture and then the idle speed. Start the engine and let it warm up for a few minutes.
Is your fast idle speed too high? Remove the wing nut that holds the air cleaner onto the top of the carburetor and set the air cleaner out of the way. Check the graph for the 1406 and look in the middle of the graph.

You don't have to have the engine cold to set fast idle. On the right side of the carburetor, locate a black, round disc held in place by three screws. This 1406 is my first edelbrock, and it went on my brand new 383.
Step 1 place the vehicle's transmission in park and open the hood. I checked float level and set it per the manual before installation. Step 2 locate the two adjustment screws on the front of the edelbrock carburetor, just below the nameplate.
