Its not the oil that causes this situition and it is not how much fuel that you run through it. Break-in most certainly helps the engine run better. No doubt about it, but a perfectly fine engine will not exhibt the problems people are having and they ARE real problems that needle settings won't get rid of fully. Needle settings help I'm sure, but won't get rid of the problem. It's more than likely it is the fuel pooling problem, but I do not see how break-in helps eleviate that. It does help all parts to mate up however.
MustangFan you need to send your engine back to DA. There is no reason to put up with a pain the in the butt like that sounds like it is.

I have not ran my DA yet, but there is one here at my field and it has ran like a Swiss clock from the first time it was flipped and now about 5 gallons later runs no different than it did the first tank except it has even more power. Idles very low and responds instantly and you can hover it forever and try to get it hot and goose it and it goes up like the Space Shuttle so it sure isn't gettnig hot. That is what a DA 50 is supposed to do. Anything else and something is wrong with it. The needles were very easy to se as I set them for the guy. That thing is as reliable as the sun coming up every morning. Hopefully mine will be too and if not I will give DA a call. They have always treated me like their long lost brother.
