I recently bought a '71 rr (383 original points ignition) with a broken tachometer (stuck on 2000) and sent the entire cluster to Gary the Tachman in S.C for repair and calibration. I installed it yesterday and although the tac works, it is slow to respond when increasing and decreasing RPMs, sort of "floats". Is this normal behavior for an original 7000 RPM rallye tachometer? The only new replacement I could find was the 8000 RPM replacement and want to keep car as original as possible. Thank you!
