Of course everyone thinks their plane is wonderful, but every plane has at least
one annoying 'feature'. I don't want to hear about cabin width or cruise speed,
but that minor gremlin you would fix if money was free and time replaceable.

In my plane, the overflow vent vents too much and full tanks cause it to
drip. Yes, I know how to fix it, and probably will next annual, but right now
it bugs me.
