[TR] 1972 Triumph TR6 spark plug question

[Chip19474 at aol.com]

Craig,
 
I'm assuming that the car runs well after the tune-up.  I don't think  that 
"cold plugs" would suddenly cause the motor to run so cold that the temp  
needle barely budges.  If the motor runs well through the gears with the  
choke in, idles nicely, doesn't seem to be putting out any soot at the 
tailpipe,  and the plugs look to be firing cleanly, I'd first suspect the temp gauge 
 circuit back to (and including) the temp sender.
 
It could be that in the process of tuning the car, the wire to  the temp 
sender was disturbed.  Also, how is the fuel gauge  responding?  There's a 
device known as a voltage stabilizer wired into the  temp gauge and fuel gauge 
circuits.....if the fuel gauge is reading a little  funky, you may want to 
check (replace is more likely) the voltage  stabilizer.  
 
I haven't seen many temp gauges go completely bad....not always accurate  
but seldom do they just quit.  The temp senders do tend to get a bit  
out-of-wack after some years.  If your engine is running well, I'm guessing  it's 
the sender/sender wire.

My  concern is after the jets were corrected and the car tuned, the 
temperture  gauge barely comes out into the white part of the  gauge
