Thanks for the info Vaughn.  It's really not a problem most of the
time.  My local flying I always burn mogas.  I'll just go back to
hotter plugs on leading.  May try the TCP next time I travel, if
I can't find a fuel stop with mogas/80.

I don't think it's temperature related due to lower direct-drive
RPM, as my temps actually run rather high.  Cruising at 5200 RPM
oil temp will still be 200 even when it's cool ambient.  I'm not sure
why, but I know I couldn't run 6500 if I had a redrive, because
my oil temp would be way over redline.

Just curious [Mr.] Mick,
What type of fouling was it? (lead, oil, etc)?
