Try some ice cold medium or retracted gap plugs gapped to .015" to .0= 10". This will show up a secondary ignition problem. If the problem goes= away, the voltage at the plug is too low for conditions. Mazda plugs are= too high a heat range
 
For climb and high load 12.7 mixture (or richer) on the (Heated) Fuel= air gage, and or 1600 degrees on the EGT.
 
You can also try pulling off just a bit of throttle to see if that cl= ears it up.
Also indicative of a secondary ignition problem.
 
Be sure primary ignition wires are run well away from secondary ignit= ion wires, and away from each other.
