#2 Full tanks increase fuel pressure, a poor seal on the
carb float needle valve will leak and fill the bowl, which
then over-flows. The tanks have about 10-15% free space
even when full to allow parking on non-level surfaces before
the tank vents begin to drain.

Hold the phone, here.

You mean fuel tanks can build up pressure with functioning vent lines?
Hummm.

If it is a bad (plugged) vent, then I'm not going to fly it until *that*
detail is fixed.
