Andrew, 

Since I didn't see any other answers, I'll jump in... the Crane ignitions
suggest a .035 gap with a stock coil, up from .025 with the stock
electronic ignition.

A wide gap makes it harder to start especially after the plug electrodes
get worn and rounded.   New cars often specify .040 to .050.   With the
extra output of the Sport coil you may get away with it.
