Wojtek, Your 2 post on these engines are merely 6 hours apart. The first one you are excited about getting an engine and running it and then less than 6 hrs later you are telling all of us that jet joe is a piece of sh&t. I am still on the sidelines on this one and unless someone who ACTUALLY has one of these engines and ACTUALLY has run it and experienced the problems post here i am not inclined to belive your post as of yet.
