Try NGK B9EV B9EGV  Gold Iridium or B9EVX Platinum. These are thin

wire

center electrode, last 50 to 100hrs on 130 Leaded fuel. B10 are

colder for

trailing.
If the wire burns away they still keep going.

Ian, I'll try a set of these next time around. If they don't foul with
lead, then problem solved!

Seems like different plug designs would be more or less susceptible to
lead, but I know nothing of the reasons behind the design of different
spark plugs and their applications.

I don't know about the lead fouling, but I'll comment about starting
after flooding.  I'm using the B9EGV in my 20B, and on a couple of
occasions during the dyno runs we had seriously flooded the engine.  I
was amazed at how quickly it cleared and started.  I had recalled horror
stories (I think Ed Andersen) about the aftermath of flooding the
engine.
