This is due to "global gravity change," an increase in gravity here since the '80s holding down the needle.   

My guess anyway, and it's effecting my weight too! 

I have the same problem and I'm going to break the instrument cover  banging on it if I don't get it fixed.  This is the real fix:  www.overseas-spedometer.com.  About $85 plus shipping, and I'll get the 10% over speed error adjusted too.

Subject: Speedo needle sits still sometimes

I've got an 84 Vanagon with a fairly recent Speedo cable.  I've had the Speedo needle not move till I knock the face of the pod a few times, more frequently lately.  Is there a known fix for this "loose needle" syndrome?
