1 Edelbrock Performer Series Carburetor Owner’s Manual 3/00 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.
2 Edelbrock Performer Series Carburetor Owner’s Manual 8/94 SECTION 1: THEOR Y OF OPERA TION 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.
3 Edelbrock Performer Series Carburetor Owner’s Manual 8/94 METERING SYSTEMS The Edelbrock carburetor has three (3) basic systems that meter fuel to the engine: The Idle System, Primary Main System, and Secondary Main System. By understanding the operation of each you will be better prepared to calibrate your carburetor.
4 Edelbrock Performer Series Carburetor Owner’s Manual 8/94 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).
5 Edelbrock Performer Series Carburetor Owner’s Manual 8/94 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.
6 Edelbrock Performer Series Carburetor Owner’s Manual 8/94 TRANSIENT CONTROL SYSTEMS In addition to the three (3) basic Metering Systems, there are two (2) Transient Control Systems; The Secondary Auxiliary System and The Pump System.
7 Edelbrock Performer Series Carburetor Owner’s Manual 8/94 “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).
8 Edelbrock Performer Series Carburetor Owner’s Manual 8/94 EXTERNAL DEVICES The function of your Edelbrock Performer Series carburetor is also dependent on several external devices; the fuel pump and air cleaner. Fuel Pumps and Pressure Avoid extremes in fuel pressure.
9 Edelbrock Performer Series Carburetor Owner’s Manual 8/94 Air Cleaners Your Edelbrock carburetor was originally calibrated with a low restriction open element air cleaner configuration; a 14”x3” Edelbrock Signature Series unit.
10 Edelbrock Performer Series Carburetor Owner’s Manual 9/01 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.
11 Edelbrock Performer Series Carburetor Owner’s Manual 9/01 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.
12 Edelbrock Performer Series Carburetor Owner’s Manual 8/94 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.
13 Edelbrock Performer Series Carburetor Owner’s Manual 8/94 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.
14 Edelbrock Performer Series Carburetor Owner’s Manual 1/01 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.

16 Edelbrock Performer Series Carburetor Owner’s Manual Rev 1/01 * = Carburetor is certified to meet U.S. Coast Guard Requirements 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.

Instead, use the rule of: “2% leaner per 1500 feet” and the Calibration Reference Chart for your model carburetor.
