The way I'm going to approach this is to test on the ground, first or= der of business is to get a test prop that will allow a full rpm ground ru= n. Then
going from simple to complex, change plugs, change the intake runner,= separate ignition primary and secondary wires, doing one step at a= time
to see if I can isolate the problem.

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.
