Anyone know what this is? It's next to the blower motor, and I'm having trouble finding out what this online. It's an '86 Tercel 4WD.

It sets the idle when the air conditioner is running, I think. I don't have the stock carb and messed with it earlier in the month. When set low, the AC kicked on earlier in the rpm range and vice versa when set higher.
