I think it holds idle for a little bit and dies. I would fly for a bit and then cut to idle as Iturned to land, would always be a deadstick. Makes it hard to 3D when you can't trust the motor, he he!
It's hard to do anything when you can't trust your motor.
I just started working with my YS110. The instructions Igot were just like you mentioned, peak idle, drop to 4000 and adjust reg, then drop to idle and adjust low end.
Did you use a tachometer? In checking yesterday, my low end held steady for about 20 seconds, then finally started surging. So make sure you are using a tachometer and giving the engine time to develop it's habits. Iam going to guess you are rich, somewhere. Check everything again with a tach, giving each step time to develop habits and burning off extra fuel and let engine cool between steps.
