Hi, well, I see brown liquid coming out from the pipe when I turn the model on the side. So I guess it is rich.

hmm, I can try increasing the idle even higher, but it already tried to drive away even at this setting. I have to grab the remote and pull the brakes every time as soon as it starts.

Do you think the problem is with the HSN? I am just thinking: if it stall on lower RPM (usually, when I break and the RPM is decreased), maybe it's the LSN, that's set too rich. What do you think?
