Quadrajet Power
APT wrench
$5.99
This tool has been selected to fit over the APT (adjustable part throttle) screw in the Quadrajets with internal APT. Both computer controlled, and non computer carbs. Remove plug from air horn and adjust your part throttle mixture. These mixture screws were factory set. Moving the screw down (clockwise) creates a leaner part throttle mixture. Be sure to use our APT plug to keep the inside of your carb clean from dirt. Note: this sale is for the single APT adjustment tool only. Other items in picture are examples of items needed.
US-sourced parts. Orders ship same or next business day from Boerne, Texas.
