Precicio drill bit set for calibration
Excellent way to find if the jets have been enlarged or original , and if they are open

Idling
I couldn’t get my carb to idle bellow 1k rpms. These bits helped me get carb to idle by drilling the idle tubes and down channel restrictors . Now I idle at 750rpms no problem. And thank you Quadrajet power for making a YouTube video on how to do this.

Handy to have, hard to find.
Handy to have, even for just cleaning out dirty orifices, or using for size verification.
