Jay, mine has a pointer on the top of the thing where the knob is.
The pointer moves forward and aft as you turn the knob. Mine's a '65
Six. I'm sure it can be adjusted, I just don't know the procedure.
Probably involves taking the trim screw assembly apart. Check the
maintenance manual.

My club bought an Archer a while ago which had screwed up rudder trim.
No matter what you did with the knob, you had to apply *left* rudder to
keep the ball in the center in cruise.

Various mechanics poked at it and couldn't fix it (didn't stop them from
billing us, though). We finally convinced one guy to actually take the
damn thing apart. Turns out some previous repair job had been botched
and the wrong part was in there. I don't remember the details, but he
got the right part and we were good as new. Before that, we were
starting to think of all sorts of crazy things like the wings were
screwed on crooked.

Rudder trim on a Cherokee is pretty simple. It's a jackscrew with some
springs pulling on the rudder bar. It shouldn't take a rocket scientist
to make it work right.
