Tachometer
I have a bouncing tachometer in a '69 912 which I can't figure out. Here are the symptoms.
1) Tach works fine when coasting (clutch is in) or in neutral at any RPM.
2) Tach bounces when in gear after 3000 rpm and gets really bad around 4000 rpm. Generally this gear has to above 2nd.
Ideas?
