Screw driver handle has flexible coiled metal shaft to allow safe and easy idle mixture screw adjustments. The end of flexible shaft has a magnetic socket allowing the bits to be held securely and easily changed for various applications.
QuadrajetParts.com modifies the socket depth of the GM bit to allow this handy tool to also work on additional idle mixture screws that require a deeper socket, other tools on the market will not fit the deeper style mixture screws. We did this to make this tool more handy, as this one tool can now be used for many styles of Quadrajet and 2G idle mixture screws.

Handle is hollow and has a screw on cap that allows for convenient storage of bits in handle. Four removable bits are included to allow adjustment on various styles of Rochester idle mixture screws:
