Well Hartmut, I tell you (as always, in the best English I can :-) As I said before, I am making a checklist with all the things which, in my opinion, and with the help of all of you, should be carried out before next flight. I know very little about this plane (this unit), but has been told that the engine and carb were changed (actual engine is a C-90 and carb has also been changed twice). I also don't know if the header tank is exactly the same in dimensions as when new. So, as one (say one) of the things we are checking is the possibility of starvation of fuel in steep attitudes, I feel the need to also check this issue just to be sure that after modifications done to the aircraft it still has the same distance between tank and carb as when came out of the factory. That is the reason. In other words, basically, because of the little information I have about the plane. Hope I was clear enough with this explanation. Of course I think that this is not the problem at all, but I have to be sure, I have to verify that, and not only think that is OK. As a member of this extraordinary group, I have this great opportunity to ask you guys and that is just what I am doing, and as I said before, is always a pleasure to hear your opinions, really a pleasure.
If we happen to see that the distance is not correct, well, then relocation of tank/carburetor should be accomplish, but I think that this is not the case, but have to be sure. Regarding valves that could stuck, I already have that item in the checklist, you or someone said that before. Good, also gonna check for the possibility of p-leads wire shortcuts. To sum up, Is not that I am not focusing on the wrong thing, I am making a wide checklist of all the things I would like to check before next flight, that's all. Of course, priorities of all the items in the checklist will not be the same. A compression test is also in the checklist as you ore someone mentioned before. Good advice that of the engine health. Well, hope I was clear enough (it is always strange to write in another language, but have no idea on how strange all of my mails sound to all of you :-) Best regards, and thanks again for all of your help !!!

I am still wondering what the benefit of your intend is. Even if you are measuring let's say one inch off, what would you do with that data? Would you relocate the carburetor or the tank? Both locations are given facts - designed to the airframe, even if a inspired mechanic did some work on your aircraft, I doubt that your plane differs in this regard from other Ercoupes. Be advised that power loss can easily happen when valves get stuck or simply a wire shortcuts itself in a nose high attitude. If that wire happens to be the p-lead of one of your magnetos, you will feel it as loss of power. If your carburetor is clean and the float level adjusted properly and the fuel supply gushes down through your gascolator in a stream, the fuel supply to your carburetor is sufficient for any flight attitude. This is part of the aircraft design. No aircraft that cuts out an engine in a steep climb would have gotten approval from the CAA. I am tending to believe that you are focusing on the wrong thing in your analysis. Heck, you can just have a malfunctioning ignition switch that shortcuts the p-leads in a nose high attitude. Did you do a compression check on the engine? I would make sure first that the health of the engine is not compromised before jumping to conclusions.

Thank you very much Bill for such an extraordinary method !!!! Now have to wait until someone can make the measure and told us the reading (remember, 415-CD with Marvel carb). Fantastic !
