Ok, so I am new to 914 ownership, but not to Porsche ownership. I seem to have discovered an interesting issue. The tach needle sometimes just starts "bouncing". Does not seem to be related to any other maneuvers - braking, lights, etc...
Any thoughts? |

Dirty points or bad tach ballest. Replace the points and condenser, reset the dwell and the timing. If the needle still bounces, replace the tach with a nice rebuilt one
