Clapp Oscillator Circuit

I am building the circuit described in this lab:  wiki.analog.com/university/courses/electronics/comms-lab-clapp-osc

Can someone please tell me the rule of thumb for selecting the choke inductor, L2?

My oscillator is designed to oscillate at 16 MHz.

Values I'm using are:

C1 = C2 = 1nF

C3 = 10 pF

L1 =  10 uH

 

If I choose the wrong value of L2, the circuit wil not oscillate.  For example, L2 = 10 mH does NOT work. 

 

Thank you
