Re: Tach rebuild

[Theo Smit <tsmit@home.com>]

To add to the fray:
Enof, you should calibrate the tach at medium RPM, not idle. With the way
the tach works (rebuilt or not) there is only one possible calibration
point, and everywhere else what you get is a function of the tach's overall
balance and bearing condition. In any case, calibration at idle is the most
likely to give wildly inaccurate readings everywhere else. Make sure that
the RPM reference you're using is known good at the calibration RPM.

Good luck,
Theo
