1984 Buick Electra Carburetor Air Horn Screw Tightening Sequence Diagram (1-13)

This document is a photographed scan (displayed on a screen) of a line-art diagram showing the top view of a carburetor casting — most likely an air horn or throttle body/float bowl top — with thirteen numbered screw locations. The numbers 1 through 13 are placed next to screw symbols around the casting, indicating the recommended tightening (torque) sequence: the two center screws (1 and 2, shown blackened for emphasis) are tightened first, followed by the screws working outward (3, 4, 5, 6, 7), then the perimeter screws (8, 9, 10, 11, 12, 13). No actual torque values, text legend, part numbers, or vehicle/year identification are printed on the diagram itself. A reader can learn only the order in which the fasteners should be tightened, not the torque specification. The scan was uploaded to the gallery of a 1984 Buick Electra and classified as a torque spec document; the diagram is consistent with a four-barrel carburetor (e.g., Rochester Quadrajet style) air horn screw sequence, but nothing in the image confirms or contradicts the claimed vehicle application.
