Need cold start help to get your race car warmed up and keep it running? Allstar Performance has just the thing--adjustable idle kits. They allow you to adjust your idle speed from inside the cockpit! All items mount inside the foot box to stay clean and away from the carb itself. They're designed to work with throttle pedals that have a flat surface on the arm, similar to how Allstar's bracket bolts to the foot box, and easily adjust against the top arm of the throttle pedal. Once your car is started, simply turn the adjustment knob to the desired idle setting. These kits come complete with an adjustment knob, a 5 ft. cable assembly, a mounting bracket, and installation hardware. Throttle pedals are sold separately.
