Hi Steve,
I'm not sure if you received an answer to your question.

If you change the cap size, you must retune the primary to resonate with 
the secondary's resonant frequency, regardless of breakrate.

If you designed your primary turns for the 0.097uF cap size (meaning, it 
resonates with the secondary), and then you change the cap to .024uF, you 
will need to increase the turns on the primary so that L1 and L2 are 
designed for the same resonant frequency.

Take care,
Bart
