CARBURETED FLOAT ADJ. TOOL ESSENTIAL NEW TOOL PACKAGE

A new essential float positioning tool package, J-34817, has been released for making float adjustments on Quadrajet, Dualjet, Varajet and Monojet carburetors. The float positioning tool, J-34817-3, permits more accurate positioning of the float at the correct checking location than was possible previously, using two fingers. Separate bending tools for each of these carburetor models are supplied in the package to assist in this float level adjustment. (Only GMC and Chevrolet Truck dealers will receive the Monojet float bending tool, J-34817-30).

This tool package is also available as part number BT-8426 from Borroughs Tool and Equipment Corporation, 2429 North Burdick Street, Kalamazoo, Michigan 49007.

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.
