When I was able to run it while visiting the Tesla museum some years
ago, I found that placing a larger topload on the secondary terminal
increased the spark length considerably.  Without the added top load,
sparking and heavy corona was plainly evident from the protective metal
plate at the top of the secondary winding.  If I can locate the photos I
took at that time, I'll post them on my web site.  They may be hard to
find - I've been looking for them for a couple of years with no luck. :(
