Tachometer pegging gauge now/FIXED
Just purchased a B21 with mechanical tach and hr cable . Found cable broke on engine side , replaced . Tach now works but seem to peg and bounce the needle past the numbers , a lot when rpms up . I know old vehicle speeds and tachs worked on magnetic pulling the needle on a clock spring to work . Is this a instrument problem or drive problem ? Searches here did not show this kind of problem .
