A little follow up on this.
A fact on the Healey that I forgot to mention is that the gauge on the car
does not return all the way to 90, bit sticks at 120. It moves smoothly up
from that point, but does sometimes stick on the way down, but a tap on the
gauge drops it back down.
I have also assumed that the temperature would still be correct as the
expansion in the tube that moves the needle would push it to it's maximum,
which is where the concern of accuracy was. I have been assuming that the
return spring was dirty and a cleaning would help this.
I had on the shelf what I "knew" to be good dual gauges (both black face
Smith GD1501/14's). I just boiled a pot of water and put the bulbs of each
into it. One gauge reads 220 while the other reads 212. I called APT and
they said that they don't just calibrate they only do full rebuild at $165
YIKES!!!
Does anyone just clean and calibrate?

Steve,
What do I need to do to check this? Does it have to go Nisonger Instrument,
APT Instruments, or MoMa's to get the gauge recalibrated?

My recommendation, then, would be to check the accuracy of the temp gauge
before doing much else.
