The whole point is not after the engine is running, Its before its running, I suppose you are going to attempt fuel the airplane upside down too?

To have this problem and not fix it when its so simple is just nonsense. To be someone who is supposidly a designer and designs in this problem is anal in the extreme for the majority of sport airplanes.

You can post an repeat yourself all you want it does not make the practice of being required to start a typical sport airplane upside down any less dangerous or completely pointless when the problem is so easily fixed in most cases.

To the original poster if you are still there fix the problem, lower the tank and forget it.
