I, out of curiosity, opened the cowl last night just too see what the engine looks like and if they removed the weights which was infront. Guess what - they were all still in there! I almost flipped - that explained why the plane so nose heavy...I'm going too discuss it with them when I take the plane tommorow so that they can cut a extra opening for airflow too the engine (I don't have a dremel tool). I also saw that the line going from the fuel tank too the muffler was torn and totally off the pin - I don't know if this hapened after, in, or before the flight on Saturday. If that line disconnects in flight - what will be the consequences? No back pressure or not really any difference? I did cut the line behind the tear and put it back.

LOL I have this akward feeling they didn't balance the plane after putting on the 61.

Oh on the topic of the CG (where too balance) - I found it made a difference as too where you put your fingers - When we first balanced the plane - if you hold your fingers near the fuse it balances with little weight in the front. As soon as you balance it with your fingers at the wing tips it was way tail heavy and you needed too add a lot of weight (this is what we did)
