Yes, it gives you more fuel which assists in more complete combustion. But
only while cold.

You should use The Knob whenever your engine is cold, or even not-so-cold as
long as it reduces white smoke.

That's normal. I use The Knob for as short as possible to get good power,
then it goes off.

Especially at 7200 feet of altitude, the rules are strictly situational.
Using qualitative judgements like "good" and "bad" are useful in these
situations.

Me too. That leak is a real bitch. Plan on control not elimination. I park
over a block of 2x10 lumber and have a piece of 1/16th cable hanging down to
prevent drops from blowing on my hatch on long trips.
