That is correct.  My college TR3's speedo never worked, my our 
neighbor who had a TR3 told be the trick. Now that I have a speedo 
that works, I can also verify it.

BTW, when I received my latest TR3, I had the same behavior in the 
speedo.  When  I adjusted the trip meter it started to work.  So you 
may want to play with that adjustment a little to see if that changes 
anything.  My felt like it was stuck in the adjust position.
