Enough supplies included to install bushings on 3 Quadrajet carburetors. Bulk 10-pack bushings are available separately (Q4311).
Most Quadrajets have worn primary throttle shaft bores. This excessive clearance allows unfiltered air to enter the engine and since the carburetor "doesn't see" this air, it can't compensate for it with the proper amount of fuel. A worn shaft can cause an erratic idle and light throttle issues.
