Product Description
Nice aluminum tool, easy to grip and turn and doesn't take up much space in your tool box. Various colors, will be shipped random.
Your order is for a single tool (1).
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.

APT Adjustment Tool
The tool did what it was suppose to do. I did make a commit that there was more play in the large slotted end than I had expected.

APT Adjustment screw tool
I bought this for my Rochester qudrajet carb and it works perfectly! It is heavy and durable and well worth the money!

Versatility of APT tool
The tool not only works for the APT but also for adjusting the Idle Jet screws on the 'Marine' Q-jets. The idle screws on Marine Q-jets use a 'flat end' just like the APT.

Makes fine tuning a breeze.
Good little tool that every Quadrajet owner should have when freshening up a Q-jet.

APT Adjustment Tool
A near perfect fit. If the tip were maybe 1/4 inch longer it would engage the rich stop as soon as it was installed in the air horn. It works perfect to get the right travel of 4/32 for this application. Thanks
