I typically have the plate closing about a third of the stack, then vary it about 1/2" or so each way to tweak the temp. That gets me about 10*.
The air intake plate should be about a half inch out and you should never have to adjust it. Sounds like you have too big of a fire. It really doesn't take much fuel to maintain temp.
