You have asked a classic question about a classic problem. There is a
simple answer. You're in the wrong hole! You're in the Bungee hole!  I ran
into the same problem you have some years ago. It was a fellow flying a
65HP coupe off of a short field in front of Leonard Page's house(Arkansas
Chicken Ranch Fly-in). Same situation, same concern as you. I raised his
tail(like a horse) and sure enough the top of his push rod was in that
forward hole.The geometry of
the arrangement increases elevator up travel.

In the early coupes elevator trim was achieved by means of a Bungee Spring
connected at the top to that forward hole and at the bottom to the
aircraft
frame and controlled by a crank on the planes panel. This spring exerted
an
adjustable and opposite force on the yoke, thus offsetting the effect of
out
of trim forces. (I'm sure there's a better way of saying that). I believe
most, if not all, of those devices have been removed in favor of the
better
trim tab. Move it to the other hole but check your measurements after you
do. There's a great temptation with the "D" models to retain the "C" model
elevator adjustment. 
Good Luck......Cliff
