Re: Tach needle calibration

[Dan Bubb <jdbubb@ix.netcom.com>]

The tach needle should point at zero when at rest. It has an internal
stop unlike the speedo that has a pin stop for the needle.
Other than getting the needle zeroed, I would think calibration would
need a specialist.

At rest, the needle now points to the middle of the water temp gauge, so I assume I need to reposition the needle.  Can anyone tell me where the tach needle should line up when at rest and/or how to calibrate the tack?
