I have two evo 46's.

In the beginning they were great! No complaints at all.

Now neither one of them run worth a crap. One has been crashed and is in rough shape, so that one is excused...

I just bought the other one early this spring. It ran great at first.

Now not only will it now run correctly, it has developed a nasty "knock".

I never run it lean, I should send it back.

However, I appreciate your warnings of not getting a more complicated engine to run, it is not my lack of understand of how the engine works that is the problem.

I have and several people at the club including the club president try to trouble shoot this engine and all come to the same conclusion I do. WHAT IS WRONG WITH THIS THING!

Maybe I just have a lemon, because my first one never gave me any problems untill I power drove it into the ground.

I think I am going to just buy another evo engine that I will replace the one that was crashed and I will send the other one back for the experts to look at.

I have to drive an hour to my club's field, so I can only go on the weekends. It is so frustrating to drive all the way there and fight the engine all day. For once, I would like to fly! This has been happening every weekend for the past 3 weeks!

Thanks for the help guys,

Wings
