1403-1413 Perf Series Carburetor Owner's Manual.qxd 3/31/2006 12:04 PM Page 1 INTRODUCTION Your Edelbrock Performer Series carburetor was calibrated using Edelbrock Performer, Performer RPM, and Torker II Power Packages. The carburetor metering was developed on Edelbrock engine dynamometers, chassis rolls, and a variety of development vehicles.
1403-1413 Perf Series Carburetor Owner's Manual.qxd 3/31/2006 12:04 PM Page 2 SECTION 1: THEORY OF OPERATION BASIC ENGINE REQUIREMENTS The spark-ignition 4-cycle engine burns a mixture of AIR and FUEL. The air is controlled by the driver’s operation of the throttle. The fuel is mixed with the incoming air by the carburetor. The Ratio of AIR to FUEL is the AIR/FUEL Ratio (A/F). This is a ratio by WEIGHT; if 12 pounds of Air are combined with 1 pound of Fuel the A/F is 12:1, or more commonly, A/F = 12.

1403-1413 Perf Series Carburetor Owner's Manual.qxd 3/31/2006 12:04 PM Page 4 Fuel is drawn through the Idle System (Figure 2) by the intake manifold vacuum that is communicated at the Idle Screw Port (8) and Transfer Slot (7). Fuel in the bowl passes through the Primary Main Jet and Metering Rod Restriction (1) and into the Primary Well (2).
1403-1413 Perf Series Carburetor Owner's Manual.qxd 3/31/2006 12:04 PM Page 5 The fuel flow rate in the Main System is proportional to the air flow rate; as air flow increases - from either an increase in throttle opening or an increase in engine speed at the same throttle opening the fuel flow also increases by nearly the same degree. At higher engine loads, such as in a heavy part-throttle acceleration, there is a need for a richer mixture.
1403-1413 Perf Series Carburetor Owner's Manual.qxd 3/31/2006 12:04 PM Page 6 Secondary Main System: The Secondary Main System (Figure 5) delivers fuel only when the secondary throttle blades and air valve are open. It ensures that fuel delivery varies with air flow. The Secondary Throttles (1) begin to open when the Primaries are about 65% open. The Primary and Secondary Throttles arrive at the WOT stop at the same time. Air flow through the Secondary side is controlled by Air Valves (2).
1403-1413 Perf Series Carburetor Owner's Manual.qxd 3/31/2006 12:04 PM Page 7 “bog” or “flat spot” on secondary opening, it is necessary to add fuel by an auxiliary means during the time the secondary is in the transient phase. This is accomplished by placing a small Discharge Nozzle (2) at a point just under the Air Valve (1). The air flow past the edge of the Air Valve creates sufficient pressure drop to pull fuel out of the Auxiliary System.
1403-1413 Perf Series Carburetor Owner's Manual.qxd 3/31/2006 12:04 PM Page 8 The pump plunger is not driven directly by the throttle, but through an intermediate Pump Drive Spring (4) that extends the duration of the “pump shot” past the time the throttle stops moving. The Edelbrock Performer Series carburetor has an external pump lever with three hole locations for link attachment providing three distinct pump delivery curves. This is further explained in “Calibrating The Pump”.
1403-1413 Perf Series Carburetor Owner's Manual.qxd 3/31/2006 12:04 PM Page 9 Air Cleaners Your Edelbrock carburetor was originally calibrated with a low restriction open element air cleaner configuration; a 14”x3” Edelbrock Signature Series unit. It was also evaluated for proper metering and vehicle performance using a variety of other air cleaner designs and will perform as intended with nearly any reasonable air cleaner design.
1403-1413 Perf Series Carburetor Owner's Manual.qxd 3/31/2006 12:04 PM Page 10 To help you calibrate your carburetor, a CALIBRATION REFERENCE CHART has been designed for each model of the Edelbrock Performer Series carburetor. These charts (pages 18—31) each consist of two sections: A Calibration Table and a Rod/Jet Reference Chart. After reading the Calibration procedures, the next step in calibrating your carburetor is to look at the Calibration Table for your model carburetor.
1403-1413 Perf Series Carburetor Owner's Manual.qxd 3/31/2006 12:04 PM Page 11 Changing Components Metering Rod and Step-Up Spring changes can typically be made in less than five minutes and without removing the carburetor. First, loosen the Step-Up Piston Cover Screws (See pg. 32) and twist the Step-Up Piston Cover Plates to the side. The Metering Rods and Step-Up Springs can now be removed and replaced if necessary.
1403-1413 Perf Series Carburetor Owner's Manual.qxd 3/31/2006 12:04 PM Page 12 Long Duration Camshaft If the engine has a fairly radical camshaft it may require an excessive amount of throttle opening for idle and/or have low idle vacuum levels. Either condition can lead to poor levels of adjustability and erratic idles. • Another fix for the above condition is to run as much spark advance as possible at idle.
03-1413 Perf Series Carburetor Owner's Manual.qxd 3/31/2006 12:04 PM Page 13 Case 2: Slower than base calibration Go to 1 stage lean Primaries and 1 lean Secondaries and perform acceleration test #3. • If test #3 is the same as base calibration, go back to the base calibration. • If test #3 is faster than base calibration, go to 2 stages lean on both the Primaries and the Secondaries.
1403-1413 Perf Series Carburetor Owner's Manual.qxd 3/31/2006 12:04 PM Page 14 CALIBRATING THE POWER MODE STAGING The Step-Up function, which moves the Metering Rod to the Power Mode, is controlled by the Step-Up Spring. The base calibration has a spring which “stages” rich at 5” Hg.

1403-1413 Perf Series Carburetor Owner's Manual.qxd 3/31/2006 12:04 PM Page 16 The length of time during which the choke will stay closed is determined by the position of the choke cap. As the choke cap is turned clockwise the choke will stay closed longer. To properly set the choke turn the choke cap to the leanest notch on the choke housing, loosen the choke housing retaining screws, and run the engine until normal operating temperature is reached.

Instead, use the rule of: “2% leaner per 1500 feet” and the Calibration Reference Chart for your model carburetor. For example, with a #1405 at baseline calibration (location #1 on the chart) and intended operation at 6000 ft.
