Thanks for the impedance clarification. That is what I meant about the use of 75 pF. These have 64 K (z)ohms at 23 kHz.
For this to work, I would try a Jfet, remove R1 and use something in the MOhms range for R2 (anything 1 to 10 MOhms may work) and use a bigger value for the source (ex...
The Colpitts oscillator uses a COIL. That is what gets you a gain greater than unity to oscillate. The junction of the two capacitors works as a midpoint tap when resonating with a coil. Thai is a 2:1 relation from base to emitter. A crystal does not do that. You have no gain here. You can try...
