Hey guys, I'm in the process of breaking in my losi xxx nt, and it seems very sluggish. I'm not talking about it takes a while to get up to speed, I'm talking about going about 15 mph the whole time. It is about 80 degrees, but no matter how much I lean it it doesn't seem to want to get up to speed. Factory of the HSN is 2.5 turns and I've leaned it down to 2. I know it's not good if you lean it too much, but how lean can I go. Or is leaning it even going to fix my problem. Thanks for your help. Will

I am using o' donnel fuel too, and I know that is supposed to be run lean. How lean though?

I think i figured it out. The slipper nut was too loose, but now that I look at the directions, it says loosen 5 turns after break in. Could this be right?? It seems that it will do what it was doing before. (I feel pretty dumb talking to myself.. LoL)

Tighten up your slipper till the engine is broken in then tune carb and slipper for performance. The diff will probably need a setting adjustment after a couple tanks also.
