Has anyone found a way to calibrate the tachs. I see a small adjusting screw on the back of my 204470321 speedster tach. See pic.
Is that for calibrating? My tach won’t go over 5800 rpm. I checked the arm and it moves freely, not sticky. I swapped it with another tach and confirmed it is indeed the tach, the engine clears 7000.
