Well first off, unless you know the guy, it's hard to trust a previous owner. Who knows what could have really happened.
As for your problem, pop out the cluster and double check the wiring. I heard somewhere about splicing the tach wire to the CAS.
If you happen to have a friend with a 240, try using his cluster in your car. If that works you can just replace your whole cluster from a junkyard.
Or you can always get an aftermarket tach

Tachs only go out for a few reasons. Either the gauge itself is bad, the ECU is bad/wrong, the RPM input sensors/wiring going to the ECU are bad [Crank/Camshaft Position Sensors (which would trigger a check engine light)], or the wiring going to/from the tach is bad....always a good idea to use year specific ECU's....good luck!
