The thermo switch and cold start valve are On or Off (binary) devices, plus they only do 
something while the starter is turning the engine, so they have no effect once the engine is 
running.

The AAR and both temp sensors are all analog, so their effects vary smoothly over a rather 
wide temperature range. In the case of the AAR, it's supposed to be fully closed by the time 
the engine oil reaches 122 F and fully open somewhere between zero and 32 F. So by 85 F it 
should be well into throttling down. This probably explains why your engine no longer lopes 
now.
