Edelbrock 1805 Thunder Series AVS 650 Carburetor Man. Choke
The Thunder Series' unique Qwik Tune Secondary Air Valve allows for limitless calibration of the secondary circuit with simple hand tools. No extra parts required for secondary tuning.
These carburetors have all of the performance features of Edelbrock's Performer carburetors, with an added twist--the Qwick Tune secondary air valve. This air valve can be easily adjusted to kick in the secondaries early or late--no extra springs are needed. These CNC-profiled, ball-burnished aluminum carbs feature black accented hardware and GM/AMC throttle linkage.
Also included with every Edelbrock carburetor is an owner's manual. These manuals consist of two sections: Section 1, Theory of Operation and Tuning Procedures, will help you to develop your own individualized calibration. Section 2, Tuning Procedures, will take you through a step-by-step procedure that will enable you to achieve a desirable calibration. For added ease of tuning, a calibration reference chart for your model of carburetor will be included.
