Sorry BIG typo in the website. The caps are .068 uf not .68.
May total tank capacitance should be .0104 uf.
So this brings us back to square one with my poor performance 24 in
discharges. I get a tune for my system with Win Tesla at about 22 turns.
The coil seems to tune to its max at 20.5 turns.I just reran the numbers an
realized that Win Tesla Was giving me to many turns / in on the secondary.
Here Are the new numbers for my coil.

Transformer: 15/60
Primary ID: 8.5
Primary wire DI: .25 Spacing .25
Number of turns 22. Tap currently at 20.5
Secondary OD: 6.25
Wire Gage 26
turns / in about 45
length 26 in
Topload:
Toroid Tube Diameter (IN)

Toroid Diameter Tube Center-to-Center (IN)
24"
Tank Cap
.0106 uf

Alex,
I ran some quick numbers on your coil - which is similar in size to mine. I
got primary turn 19.5 for the tap point, which is not far from what you have
found. If the caps are good, I would suspect either the transformer or the
primary spark gap is the problem. What kind of coupling do you have? I have
the bottom turn of my secondary just even with the top level of the flat
primary coil.
