i tested 100 pf the voltage is about 1 volts when i put 20 pf for c13 and c14 the output is 0 volt but there is another problem when i connect the quartz the output is 0.6 volts
You have to increase the total value of C2 / C3 / C4, ie put only C2 = 1pF, if not enough it increases to 2pF until the output voltage is in the range 3 - 6V (non-critical).
Remember that with two or three capacitors in series the total capacity is less.
