ED: No, that happened to Kevin Lee, but it is interesting to hear all experiences about this problem to discover which the origin of the fail could be, or possible origins, or possible combination of causes that could produce it. When this happened to my friend, the plane was in a steep angle of attack and steep angle of climb. Daniel

That seems backward to me. I *think* it only happens when the plane is light and can climb at a very steep angle (steep actual climb plus steep angle of attack). I’ll have to wait and see if someone can give you the height “d” from the bottom of the nose tank to the carb inlet as measured with the plane level. I have no way here to calculate or measure it.

You wrote:"Only if your plane is very light, flying solo, and the weather is cold so the engine is extra powerful, is it possible to get the nose so high that fuel does not flow properly to the engine. Not all Ercoupes can get the nose this high. As soon as the nose is lowered, power returns." This is exactly what I was waiting to hear !!!!!!!! It is hard to believe that this could happen, but we think that this could be the reason why the power went down soon after take off, when in a steep angle of climb (that was the case). It is the first time I hear this, and I insist, it is hard to believe to me that this could happen to a plane, but of course, physically possible. So, now talking about this issue, I attach a drawing I made, so if any of you can tell me the distance showed in the graphic (I called "d"). My friend's Erco Engine is a C90 and carburetor has been changed, so, perhaps is something wrong with that distance. Best regards, and thank you very much again for all of your help !!!
