I've had problems with jumpy, inaccurate tachs on older models.  I've tried
adjusting them with the little screw on the back but once on the road it may
read about 500 rpm too high or low or jump up and down about 500 rpms but
not consistently.  I can't find any poor connections.  The models involved
are a 71 BGT and a 69 Midget.

Erich.........

Can't help with the rear end noise (could be many things) but the tach
problem is not the cable - it doesn't have one. Yours is an electric tach.,
and it appears to suffer from the same symptoms as most of the tachs fitted
to 77 - 80 MGBs. Dunno why, they just are slow to start working.......

As for your problem with your wife wanting to use the car, just tell her
that until the tach problem is resolved, it could mean the car might break
down at any moment, anywhere, for no apparent reason.............
