#### MODELS AFFECTED: ALL WITH VARAJET AND QUADRAJET CARBURETORS

The material known as Dag 213 has been used during production of some Quadrajet and Varajet carburetors to enhance the sealing of the secondary throttle valves. This material is removed from the throttle body when soaked in carburetor cleaner. For those service related personnel who have inquired about its availability, one source for the material is Mr. G. A. Werner, P.O. Box 922, Rochester, NY 14603.

The material is available in various quantities, from a two ounce container up to one pint.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
