mga water temp gauge prob.

[dave houser <mgs4dave@tampabay.rr.com>]

Listers,
Just came back from a run in the 1960 MGA coupe of mine and noticed the 
temp gauge was on 120 degrees, barely off the mark. First time this has 
happened. Car has sat for a while, battery was dead and needed a charge 
to get her going again. What's the consensus of the group? Time to find 
a new gauge, thermostat stuck,....??
what should I try next? Aside from the gauge not working , what risk do 
I have if I keep driving this way?
TIA,
Dave Houser
