Do NOT touch anything inside the cap...or even blowing it clean with
your mouth...all it takes is that one tiny drop...
Do NOT hose off, pressure wash, etc around the dist, wires and plugs
Replace the wires with spiral wound SS *WIRE* that has an inductive
core that the wire is wound around. One of your leads could have gone
bad, going bad or been pulled to frey/break the carbon filled fiber
glass 'wire' conductor.
Use spark plug grease on both the cap and spark plugs
DO NOT do this while your hands are dirty. A finger print can become
the carbon track after one flash over
Check your coil...it maybe over voltage and/or have you gone to an
after market coil and/or system? When I had kit capacitor ignitions...some
times it would do this if everything was NOT perfect
Consider modifying your spark-plugs to have less resistance to the
jump over on the center to ground...or more correctly...takes less
voltage to jump employing the corona effect

PS...I'm not a fan of platinum plugs...they are just good enough
and are mainly for that 100,000 mile change interval...
