Rick and CarloSW2,
I like Iridium plugs in a small engine - several im my experience have gone 150k+ miles before needing change.
Plus, if I'm correct, won't larger gap size help FE to a small extent at low RPM?

By piston soak, are you referring to a SeaFoam treatment?

Kudos on the improvement, especially in January.
