Have you checked all your grounds and fuses? If so on to the tach filter. $29 at www.rodneydickman.com or $59 at Ecklers for one that looks like the original.
It is mounted on the intake between the carb and the dist. It's a small round object that looks like a condensor.

Dont know what your does or what the fix is but my tach works for a little while and then gets hung around 2k rpm. Once the car is warmed up, it frees itself and then works normally.
