FYI - Refer to the attachments in this post and the next two posts:
"All 1968 and some 1969 Chevrolet equipped with the Quadrajet 4-barrel carburetor have a type of fast idle cam that could crack and eventually separate from the carburetor. If this occurs, a section of the cam could become lodged in the throttle linkage and cause the throttle to be held in a partially open position. If this should occur while the vehicle is in motion, the vehicle will not slow down when the driver removes his foot from the accelerator pedal. While this is a remote possibility, if it does occur, the driver should shift the transmission into neutral, apply the brakes and bring the vehicle to a complete stop.
Install a new type fast idle cam on vehicles involved in this campaign in accordance with the instructions in this bulletin."
Applies to all 1968 and 1969 prior to LOS VIN L-523411 and Norwood VIN N-599752 (approximately mid-February 1969).
