[T2] auxiliary air regulator question

[doktortim at rockisland.com]

Put it in the freezer for half an hour. Should be not quite fully closed
at zero degrees f. At room temp 70 degrees or so, should be about half or
more open. Then hook it back up to the wires and turn on the key, or just
feed it direct from a battery. In about 2 minutes from the freezer should
be fully open.
