Presumably this is operational tuning, yes?  If you attempted to tune
using scope/sig gen with the transformer connected I would have 
expected a difference. But in operation, The sparkgap should be 
leaving the transformer out of the ringing circuit (shorting it) - 
or do you have the primary capacitor connected across the transformer?
