33nF was for a sync rotary gap not a static gap.  A 12/180 would need a
resonant value of 40nF.  A static gap LTR value of 56nF.  And a sync gap LTR
value of 104nF (close to 99nF).  Johnathon is correct that you can simply
multiply the capacitor needs to get to a match for a particular NST current. 
The static gap tables are at:
