hllywdb / George:

Thanks for the advice. I take the fuel to the field in a 0.5 liter bottle, but didn´t know about disconnecting the fuel lines.

And now I remember that the last time I flew, it was on sunset and as soon as I landed (hard landing ) cleaned the plane and took it back home without checking if the engine had some fuel inside or remaining in the tank.

Regards

Claudio
