Speedometer Gauge questions

Greetings,
I'm getting ready to get put my Super on the road, but am hoping to address I have. The speedometer gauge has stopped working...in fact the needle is still pointing at the 20 km/h mark when stopped. If I recall correctly, it appeared "sticky" when traveling at higher speeds and would then slowly return to 20, but it would never track actual speed. What has me puzzled is that the odometer is working correctly and tracks distance properly. I haven't taken the gauge cluster out yet, but I believe that both the speedometer and odometer use the same cable as their "input".

I read the thread about greasing the cable, but since the odometer is working, I don't think this will solve my problem. Do you think this is just a bad gauge that will need to be replaced to fix the issue?

I appreciate any insight anyone can provide....

Sounds like the cable is OK, but the speedo is bad.

Yes the speedo and odo work off the same cable. Probably the cable is turning OK, which is mechanically connected to the odo, but magnetically connected to the speedo, and something in the speedo mechanism sounds stuck.

You can verify the cable is turning OK by disconnecting it at the top, and while the trans is turning (driving or otherwise), feel if the cable insert is turning.

In addition to the shop mentioned, Palo Alto Speedo here in Calif is a good place, though expensive. The cleaned and serviced the tach and speedo on my Super, and made up a cable for my Giulietta.
