Now, when I got checked out in my first low wing airplane, also a
cherokee, I was told to select the intended tank for takeoff just after
engine start, if necessary. that way, if there were something wrong with
teh supply from that tank, you'd know a looong time before you rolled.

The procedure our school use is to start the engine from the tank with the
least fuel, and use that tank to taxi to the point where you do your power
checks. Then you switch to the tank with the most in, and do the power
checks from there.

That way you've tested the feed from both tanks, and aren't fiddling with
the fuel selector for ages (the entire time it takes you to do the power
checks and get into position on the runway) before taking off, so you'd know
well in advance if you'd inadvertantly turned the fuel off or selected a
tank that couldn't feed fuel.
