I am having some difficulty with my new evo engine. It says it comes pre set. However, the low speed adjustment can easily be knocked around by pumping it on something. I think thats what I did.

Heres's the problem. When running wide open sometimes it slowly dies. I adjust the low speed needle and something else will happen, like it will die right off, or it will studer and act likeits going to die until I bring it back to idle. Some times it runs perfect wide open for for 10 15 seconds, then I slam it to idle, back up, down and it don't hesitate, then all the suden at full throttle again, it will studder and die.

The directions arent that clean. It says if the engine studders, smokes, then dies when giving throttle quickly its too rich. Then is say if the engine dies when giving throttle quickly, its too lean. Well, thats a fine line. Its hard for me to tell the two scenerios apart. It seems it smokes just a tad sometimes. Anyway, I'm trying to adjust it and I am not sure of a way to determine which way to go to get it right. I would hate to have to dead stick land on my first flight. I would probably dead stick it right into something I shouldn't.

Is there any place on the net, or do you have any suggestions and a quick way to determine which way to go, lean or rich. I assume the problem is in the low speed becaues it was factory set and the high speed looks pretty secure, as in I can mess it up by "bumping" it.

Thanks,
