Replacement Rochester Quadrajet carburetor tension (windup) spring is used to provide tension to the secondary air valve. Factory spring is known to break when wound too tightly. Replaces broken or weak original spring. Handy to keep a few of these springs in your tool box for when the original spring does break.
