Hello everyone,


I now have about 75 hours of flight time on my EX2 and everything is going well. I enjoy beautiful weekly flights in the Italian Alps.


I had a small technical problem this week about which I'd like to get your opinion.


Usually, I park my plane in the hangar with the fuel selector closed and leave the mixture on "cut-off". When I go flying, I open my fuel selector to "both" and start my external. This week, after opening the fuel selector, fuel began to flow severely from under the carburetor. The leak worsened when I moved the mixture back to full-rich, and stopped when I put the fuel selector back to off. The leak occurred 3 times and then stopped.


I opened everything, checked all the drains and opened the gascolator; there wasn't the slightest trace of dirt in the fuel. The leak has not recurred.


What could be the transient problem that caused this fuel leak?


Thank you for your help and best wishes for 2024!

Y.
