how can i tell if my automatic choke is staying on when it shouldn't?

What is worth checking as well is the rivet that secures one end of the
heater element to the 12 volt connector.
If that rivet works loose you may very well have 12 volts to the heater but
you will loose ~3-6 volts . What I do is get a punch (about a 3/16 inch
end) in a vice, locate that on the end of the rivet inside the choke cover
and give a GENTLE tap to the outside of rivet. Not too heavy, you dont want
rivet
to cut through the heater wire
