The wire to the tachometer might be picking-up some high voltage radiation from the spark plug wires and/or coil.
1. Shield the tachometer wire (not easy).
2. Route the tach wire away from any high voltage wire.
3. Use a resistive high voltage wire from the coil to the distributor.

If the coil has a plastic body, this might be part of the problem.
