[Healeys] speedo stuck at 78 MPH

[Bob Spidell]

re: "As the needle is stuck, it sounds like the movement/bearing is sticky."

Yep. Hence the 'tap the face of the gauge trick' (for dramatic effect, 
if nothing else).

Side note: I've taken several speedos apart and actually got one or two 
back together. I expected to see an alleged 'jeweled bearing,' but as 
far as I could tell it was brass-on-brass (the brass needle spindle 
against a brass pocket). No Swiss watch stuff.
