[Healeys] Healey 100-4/6 Tach

[Bob Spidell]

Tried that. Will try rerouting the sleeve.

I'm pretty familiar with the speedos, having a drawerful and actually 
getting a couple to work halfway decent. A cracked odo or tripmeter 
drive gear will give a fixed-interval bounce based on speed, and the 
cable loading-up and unloading is also fairly rhythmic, but my tach just 
goes crazy. It seems like the needle needs to be damped somehow.
