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. 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. With the engine running,
slowly turn the choke cap clockwise until the choke valve begins to close. Now turn the choke
housing one notch counterclockwise (LEAN) and tighten the choke housing retaining screws. Periodic
readjustment of the choke will be required as the temperature changes throughout the year. After
each adjustment verify that the choke valve opens fully after the engine is warm.
SPECIAL CALIBRATIONS
The preceding calibrations and adjustments apply to carburetors used in general street applications.
In the following extreme instances, special calibration procedures may need to be followed.
Off-Road
Although the Edelbrock Performer Series carburetor was not calibrated with hill climbing and other
extreme off-road operation in mind, it can be made to perform superbly by substituting Edelbrock
#1465 spring loaded needle and seat for the original needle and seat. The spring loaded needle and
seat act like a shock absorber, reducing the possibility of flooding during off-road operation. After
installation of the new needle and seat you must reset the float level to 7/16" and drop the float drop
to 15/16 to 1" as outlined in “FLOAT ADJUSTMENT”.
High Fuel Flow
When evidence of fuel starvation exists, first ensure that proper pressure (4-5 psi minimum) is
maintained at WOT. If proper fuel pressure is supplied and fuel starvation still exists, it may be
necessary to change the needle and seat to a larger size (#1466). Do not make this change unless
absolutely required, as the smaller inlet is preferred for proper fuel control under most conditions.
High Altitude
Altitude has a direct effect on the operation of most carburetors. As the altitude increases, the air
becomes less dense so a carburetor, originally calibrated at low altitude, delivers too much fuel and
the engine runs richer. If the preceding tuning procedure is performed on an Edelbrock Performer
Series carburetor, a proper high altitude calibration will result. If the vehicle was calibrated at lower
