Hey I'm a lurker I check this board everyday at least once since I joined. I don't usually post because I'm more into rock crawlers than anything else. But I seem to have engine problems on my Losi XXX-nt. The engine is a Nova rossi CX .12 non-pullstart race engine with slide carb. I drove it until last fall when I was romping through a very dusty bmx style jump course. The air filter came off and sucked tons of dust into the engine. So I disassebled the entire engine and removed every last scrap of dust. I sent the sleeve and piston away to get honed, polished, and resized. It came back like new I installed it in the engine, I lubed it with after run. I put a new glow plug in, cleaned the carb and set the needles to the factory specs. Oiled and put a new air filter element on. So new engine right? I can get it started but I can even idle through a tank. It just runs for a little bit then sputters and dies I thought maybe it was my tuning so I riched the high speed needle up a little. When its rich I can see a mist of fuel spraying out the pipe. Leaning the engine out does not fix anything but the fuel spray. I played with the idle screw for a while didn't seem to fix it. I though you know what? Maybe my nitro is old so today I went and picked up a new gallon of 20%, no luck. Also it seems to get really hot before it dies. I've checked the engine over several times and I can't figure it out.
