Billa.. I've had a couple of DA 50's (great engines), and each time when the bogging began after starting and large needle changes were needed, the carb screens were clogged. One time, the large screen and the small screen under the brass plug were both dirty. After cleaning, both engines ran great again.
Just curious and in case I missed it, you said your friend flew a whole session with the DA running perfectly. Did you mean 1 flight or 1 day. The reason I'm asking is, one day my 50 ran great for a few flights and then started to bog. Looked at the large screen in the carb and it had clear gel(stuff) clogging it. I talked to MFuess about it and he said my fuel probably had moisture in it. Cleaned the screen, fuel tank, and threw out that fuel. Runs perfectly. Bottom line, most cases for me have been the screens in the carbs.
