This is really just a switch, which should either be open or closed 
(infinite or zero resistance.) However there were several different 
switches used in different years which switch at different temps.

Russ likes to disable them, but the one in my 73 has always been 
fine. I don't think it is possible that your CSV is worn out, but it is 
possible that you have the wrong switch. Could that have been 
changed at some time?   

It's also possible that someone cranked up the fuel pressure at 
some time and this pushes you over the edge in richness. And 
then there is the possibility that your voltage regulator is worn out 
and running things rich, although that should not affect the FI when 
starting, other than the fact that your battery will not be getting a 
full charge. A weak battery cranking the engine slowly is more 
likely to flood.
