[Healeys] Tach way off

[bjsbj8 at gmail.com (Bob Johnson)]

Using my digital tach to set the tach in the car, they line up really
well.both agree at 3500rpm and are close otherwise. However when c driving,
according to the chart I have, at 60mph, 4th od, rpms s/b 2550. Tach reads
5200. Anyone have any ideas. Moma rebuilt it about 5000 miles ago. Its never
been right on, but this is ridiculous. I use gps as speedo. A really neat
app from android market called ulysse speedometer. Even has hud display.
