Why would I need the microswitch then? Unless the hand throttle era cars required that the CSV ran longer than the later cars. If I simply disable the AAV/AAR/Decel setup and plan to feather the gas with my foot for 30 seconds on cold starts, will I need the microswitch?

On hand throttle cars, the micro switch served a similar purpose as the thermo switch. The cold start valve (actually a solenoid) receives power via the start circuit but in hand throttle cars, the
ground connection to the solenoid is via the micro-switch--pulling up on the lever grounds the circuit to the solenoid allowing it to spray. When the lever is down, the ground connection is open and the solenoid will not spray even when the starting circuit is energized, unless you push down on the gas pedal to (again) operate the micro-switch and ground the solenoid. That same function is performed by the thermo-time switch on your current set up, and if you keep it, you will not need the micro-switch on the throttle body. However, to allow more incoming air for cold starts that is currently done through the AAR, you will need to still pull up the lever or feather the pedal, as you currently do.
