I've been searching the forums for repairing a Speedometer needle that jumps and wondering if you have the same "oil the wick" advice for this symptom? I notice as I drive, the needle jumps to 10-12 mph faster than I am actually traveling. When stopped, it sits at the 5 mph mark. Any advice is greatly appreciated! This is on a 54 3100 btw.
Have you lubed or replaced the cable already? Always try that first.
