The tachometer on my B21 sometimes over states the RPM. The tachometer maxes out at 3,000 rpm. When it is working correctly full throttle is below 3,000 rpm. When it has the issue it will read way beyond 3,000 rpm when the throttle is over 1/2. Initially this was intermittent but it has become more common.
Can you suggest where I should start looking to diagnose this?
Thanks in advance for all advice.
