.1uf is too large for a 15/30. Best cap is a .007 to .008uf range. You will 
not get great sparks form a 4" ball. Better if you use an 8" or so. 
Sometimes black plastic components such as primary blocks can conduct, and 
drain  power out of your system. Make sure that you are not loosing power 
there.
You may also need a few more turns on the primary for the secondary size 
that you have.
