I know those things quite well. In my experience, they are VERY 
unstable inductors. They are horribly temperature sensitive and were 
never designed to be part of a frequency-determining network. They 
work OK as an RF choke in certain circuits, but I would never attempt 
to use one in a VFO.

What is the value of the inductance which you need?
