I removed the fork this morning and inspected the strut which was dry =
inside.
Bled off the pressure and removed the little valve stem piece thingy, =
collapsed the strut and no oil came out.
I added a bit more than 1oz of fork oil which was just enough to have =
the oil flow from the valve with the strut collapsed.
Worked the nose wheel side to side and could hear some air inside so =
kept doing this as well as collapsing/extending the strut. After a =
while, no air bubbles could be heard. But I have one observation and =
don't know if it's normal or not since I don't know how the dampening is =
accomplished inside. With the wheel centered or in any other position =
right or left, I can move the wheel perhaps a degree or two either side =
and don't feel as much dampening as I do when turning the wheel further =
left or right. Seems like a dead or null zone either side of where the =
wheel is positioned. I'll check again in the morning and then pressurize =
the strut and then see how it feels.

My tire pressures are 60 on the mains and 55 on the nose as recommended =
by a well known Lancair GURU...
Thorough inspection of the engine mount shows all normal and wheel =
bearings are correctly loaded.
