On the BJ8 electronic tach, there is an adjustment, but it's not accessible
until you take the tach guts out of the case.  While I had the thing
disassembled to convert it to negative ground, I drilled a hole in the case
in line with the adjustment screw.  As a dust cover, I put a strip of
electrical tape over the hole.  Now, if the tach needs adjustment I can do
it without removing the tach from the dash.

(I think) all BJ8s have an electronic tach.  Mine read high until I
calibrated it--it's
a simple process; just adjusting a trim pot(entiometer) on the back.   I
think this
process is documented somewhere.

I'd try that before I'd "rebuild"--not sure there's much to rebuild in
there (esp. if
it's reading high).
