More on the tach

[Dennis <mg-dennis@mindspring.com>]

Getting back to my tach this evening I dissasembled it.  I find that
there is an adjustment pot and I'm able to calabrate it to a dwell/tach
meter.  The needle will intermitently start swinging, usually above
3000.  I know for about $100 I can send it to a rebuilder.  But what do
they do to it?  What usually needs to be done to it to get a steady
needle?
