Intersting. I wonder iof some one wired the thermo time switch to activate the cold start valve. This is not stock. you can check the 1973.5 diagrams here to verify.

In my car, you pull the hand throttle up all the way to start. When you do this, two things happen: You get a very high starting rpm; and it closes a microswitch that provides power to the cold start valve. Power is only on the microswitch when you crank the engine as the power source is the same one that tells the starter motor to crank.
